Strong force Definition and 99 Threads

First, I did read this article on Byrons: https://www.physicsforums.com/insights/a-beginners-guide-to-baryons/. If the answer to my question is in there, I'm sorry, but I missed it somehow. Honestly, much of that article went over my head. Other than that, it's as the TLDR says. I have heard...

The strong nuclear force keeps the protons together. The larger the number of protons, the larger the nucleus, but the weaker the bonds between the protons as the radius of the nucleus increases and more unstable is the element. However, since the strong nuclear force originates from within each...

The binding energy per nucleon for each element has a specific pattern. It increases from hydrogen to iron and then decreases again. What is the fundamental reason why the binding energy per nucleon has this pattern? According to my investigation, the range of action of the strong force is...

My professor and the book I'm reading (Particles and Nuclei: An Introduction to the Physical Concepts by Povh et al.) says that "The emitted nucleons are primarily neutrons since they are not hindered by the Coulomb threshold" which means that a neutron has a separation energy lower than a...

To put it simply: Why do we have the strong force? If the goal of the fundamental forces (in a heavily generalized sense) is to bring particles to a lower state of energy, how is the strong force participating to this? Could it be due to atoms being a very stable configuration? If this is the...

Is there an experiment that shows strong force grows with distance?

I understand how the existence of quarks is inferred from the three particle-emitting cones or jets and by the quarks’ ability to deflect particles passing through the composite particle, but I don’t see how the existence of gluons is conclusively demonstrated by this rather than just being an...

So I am aware that the strong force is the strongest force with the electromagnetic force being the second strongest force. I am wondering how we go about the process of deciding which force is stronger. I am visualizing a helium nucleus; two protons, two neutrons. The two protons are...

Have there been any measurements of the strong force? Also its curve of the strength of the force vs distance

The (residual) strong force between nucleons can be desribed as - The exchange of a meson (from a nucleon to the other), as in picture b) - The exchange of a quark and an antiquark: in picture a) one nucleon "gives" a quark and receive an antiquark and it's the opposite for the other I do...

The deuterium exists only with the proton and neutron of aligned spin, which suggests that the residual strong force is greated with aligned spins, i.e. the binding energy is greater if the spins are aligned. On the other hand the mass of ##\Delta^{+}## is greater than the mass of proton ##p##...

Consider a scattering between two particles a and b that produces two particles c and d: d is stable, while c decays in two other different particles e and f. The first interaction is by strong force (time of interaction ##t_1\sim 10^{-23}s##, which is also the time of generation of c and d)...

Hi, I was wondering if there is a mechanism to explain how the strong force leads to an energy release when two light nuclei such as hydrogen fuse together. I get that the products of fusion have less mass than the reactants and that this "missing" mass is converted into energy in accordance...

I've heard that the weak nuclear force is stronger than the electromagnetic force at distances of 10^-18 m. I've also heard that the strong force becomes repulsive at a distance of 0.7 fm. So if two quarks got to a distance of <<10^-18 m which force would win, the strong force or the weak force?

Hi, Please could someone explain the differences between the strong interaction (force that hold nucleons together) and the strong force (force that holds quarks together) in terms of the exchange particles. I have been reading several online sources and there seems to be some disagreement...

I'm reading Griffith's Introduction to Elementary Particles and it says that when Yukawa proposed his theory of the strong force, it was an indication that the meadiator of that force must be a heavy particle since the force is a short ranged force. Why is that the case? I cannot get the...

In the electromagnetic interaction, opposite electric charges q attract each other. In the strong nuclear force, the proton p(uud) is attracted to p(uud) and the neutron n(udd), and n(udd) is attracted to p(uud) and n(udd). Both neutrons and protons have a hypercharge Y=+1, and 3rd...

In addition. 1. what is the presure of this force (alternativly wat is the efferctiv area it is acting on?...nucleai corrss section area?).

We can quantify the three other forces but not this one. Why?

Gluons are often depicted as fundamental particles in the Standard Model. But in looking at their mechanism, it seems they are not really fundamental particles in the sense that they are fundamental, indivisible, building blocks. They are mesons- a composite quark-antiquark pair, where their...

I read that hadrons are in colour singlet state and that gluons are not and that the colour singlet gluon is forbidden for the reason of making strong force a long range force otherwise (and that SU(3) has 8 generators and thus 8 gluons) but my question is: are mesons in a colour singlet state...

I apologize if this question seems like gibberish, Its been annoying me. I tried to ask this once but i didnt ask it properly. If there was a complex structure of sub atomic particles, and each sub atomic particle was in its individual space time vector, or eigenstate, and they where each...

When 2 protons fuse in a star, does the fusion rely on how strong the gravitational pressure is from the star so it gets past the strong force so the nuclei fuse or the temperature because of the pressure or both?

Why does STRONG FORCE fail regarding complex structures of sub atomic particles when wave functions collapse @ entangled superpositions. Why does it not continue to function keeping the particles bound yet unentangled with the observed Eigenstate being it was originally binding such particles @...

How come gravity and electromagnetism have an infinite range, while the strong nuclear force dies out quickly? I understand that the weak force's bosons, the W+, W- and Z (neutral), have relatively large mass, and decay quickly, while the photon and the graviton (theoretical carrier of gravity)...

Are there strong interactional equivalents of synchrotron, bremsstrahlung and cerenkov radiation? Or for the weak/gravitational interactions? For example, will an accelerating bare quark emit gluons?

http://math.ucr.edu/home/baez/physics/Quantum/casimir.html http://abyss.uoregon.edu/~js/ast123/lectures/lec17.html The Casimir force is simply a pressure difference in the quantum foam exerting a force upon two plates, but is the strong nuclear force the same thing? Is it a pressure difference...

I'm a bit confused now i understand that when one observes a particle for example @ Eigenstate A all its superpositions collapse because they are entangled with A which leaves them no longer entangled. My dilemma and maybe you can help me, is that If you observe a complex structure of sub...

I may be misguided here but to my understanding, separate nucleons have a higher mass altogether than the combined nucleus as the potential energy gained from being separated (in the field of the strong force) is being manifested in more mass. If this is true, and if it's not I'd like to know...

Hello everyone, Why does the residual strong force arise? Hadrons carry no net color charge, so why are they experiencing the strong force?

Please can you help, I have seen an exam question which asks which interaction is responsible for the following ... Pi+ + proton >>>>> K+ + unknown particle X The options for the answer include both the weak and the strong force. The actual answer is the strong force. What I would...

hi, I've heard that protons has most of their mass from their electromagnetic and strong interactions between their quarks, but specifically, how does that make mass? and if so, what is intrinsic mass then? and pions has 2 quarks and strong and electro interactions, why doesn't it has mass...

Are there any particles which have a neutral electrical charge and are not affected by the weak or strong nuclear force? Thank you for your time and please excuse me if I'm being very ignorant!

What is the entropy of weak and strong force? Can we determine their entropy? If so, I would like to know the formula of determining this. Thanks:wink:

Consider ##\Sigma^0 \rightarrow \Lambda + \pi^0##. (Not Allowed) According to griffiths, this strong interaction is not allowed by 'Conservation of Energy'. I'm not sure why, as this simply shows an up and anti-up quark coming together, producing a gluon, where mass of gluon is mass of up and...

I wasn't sure where to post this, but about a week ago, I sat a test called GAMSAT which has a science section comprising 20% physics, 40% chemistry and 40% biology. Physics isn't exactly my strong point, however, the developers cite needing only high school level understanding (I stopped...

Please explain how is exactly strong force caused, I've come across various answers but haven't yet received a complete answer. What is the nature of the strong force? P.S: If this is the wrong thread, Please RE-LOCATE and do not remove please. :)

In an effort to clarify my question, allow me first of all to state what I believe I DO understand: All observed elementary particles are either fermions or bosons. Ignoring the Higgs boson (which gives other particles mass via the Higgs mechanism), there are four forces operating in the...

I heard that one of Euler's Beta/Gamma function identities models the strong force. I was just wondering how it did this. (This might be a stupid question) How do we measure the strong force, and how is it a function of two variables?

So I've been set a computational problem regarding applying the Shroedinger equation to quarkonium and I'm just trying to do some research around the subject because it's nothing like I've ever covered before and quite fascinating. There's quite a few questions that I can't find answers to...

The mass of the nucleons (and, by extension, most of the visible universe) is caused by the energy stored up in the force field of the strong nuclear force. Please Explain this to me in layman's terms. I would appreciate the help. (I am being polite because phinds said so). How does the energy...

I got to wondering about this the other day so I tried looking it up but I could not find anything. All j could find was that it had a maximum force of 10,00N. I tried to calculate the electrostatic force of a helium atom because if the strong force has to hold the atoms nuclei together jt has...

In the ψ below, there are 4 components for the Dirac spinnor times three possible color states for a total of 12 components for ψ? Are there low energy, weak field limits of the above that allow us to consider classical color counterparts of electric current densities and electric charge...

has anyone tried to merge gravity and the strong force mathematically? The two seem very compatible--the gloun is the only vector boson capable of causing a force to be applied between two similarly charged objects. Isn't it likely that there is some kind of gluonic field, which behaves...

Whenever people begin to explain the nuclear strong force, they relate it to electricity. I was wondering if color charges, besides also interacting with one another in a way that's analogous to electricity, can also interact in a way that's analogous to magnetism. I have asked some professors...

For an Ap Physics Homework assignment our teacher had us calculate the Nuclear Strong Force for a Helium nucleus with a diameter of 2 femtometers. However, the intention was to calculate the nuclear strong force by assuming that the nucleus is intact, in such a case the particles would not be...

what is the difference between strong force and residual strong force ?what is its range?

Hello everybody! :shy: What is the strength of the strong force between, for instance, a proton and a neutron separated by a distance on the order of femtometers (1fm and 2fm and 3fm) in Newton? Thank you in advance! ∞
