Particle physics Definition and 509 Threads

hello all It's probably already been noted but... have people seen the paper hep/th-0810.3328? "A simple introduction to particle physics"? It looks like a very nice introduction to the maths behind the development of particle physics for advanced undegraduates and experimental...

I plan to study particle physics especially about the quantum field theory but i don't know how to start with. I have studied mechanics,modern physics,electromagnetism using Serway Physics for Sciencetist and Engineers.I have also studied Waves and Vibrations using H.J Paind Book and also...

I'm a 14 year old, living in Ireland. The country where many great authors and poets have come from. Unfortunately not nearly enough particle physicists. So my question is: How do I learn as much as I can about particle physics. There's only so many books you can read before you start to just...

Hi, I am new to the area of particle physics and I am still in high school and I was wondering if somebody could answer a few questions that I have. 1) Where is a good school in Canada to go to for particle physics 2) Can for example 8 up quarks be combined together using strong nuclear...

Where do you see Particle Physics/CERN heading in the next 50-100 years? What will come after the LHC? What research will come after the completion of the ATLAS, ALICE, CMS, and LHCb experiments? How will the discovery of the Higgs Boson impact research in other areas of physics, both...

Hi, I'm sorry if this is in the wrong forum. I've been interested in science for while a white, most notably theoretical physics. In the end, I decided to go for a degree in Computer Science, but haven't lost my interest in physics. With the introduction of CERN, I'd be interested if...

I am interested in physics. Everything about the universe excites me. I have a teeny tiny understanding of physics and the universe, though any equations I memorized during my school days have long since been forgotten. My question is; Does every particle have its own resonance frequency...

Does anyone know where to find the standard model of particle physics shown by Brian Cox in his LHC TED talk (found around 6:35 here: http://www.youtube.com/watch?v=_6uKZWnJLCM)? I'm looking to print out the equation but can't find it anywhere. Thanks

Hi, as well as applying to US gradschools (you may have seen some of my other threads...) I also intend to apply to UK places (I would ultimatley prefer to go a US gradschool, but I need some insurance incase I mess up the PGRE, and don't get accepted anywhere, or anywhere half decent). I'm...

Okay, so I'm going to be a senior in high school and it's time to start thinking about college. My interests are astronomy/astrophysics, particle/ quantum physics, and nuclear physics. This is cool and all, but I can't decided on which one or combonation of them to major in. I have a love for...

Any suggestions on text which could better my understanding of the mathematics governing particle physics? I am in my fourth year of my B.A.Sc. engineering physics degree, so I have a fairly strong math background as is. Thanks in advance.

Hi: I've heard that in electromagnetism, there is a system of units called Lorentz - Heaviside system, and that in particle physics, tis system is used insted of the gaussian or the SI. Why do particle physicist use this system? and by the way, How do we go from the Gaussian...

TASI 2008 (Theoretical Advanced Studies Institute in Elementary Particle Physics at the University of Colorado in Boulder) is almost wrapped up, and they're getting videos of the lectures (and slides) online faster than I expected. You can find them here, and it looks like they'll all be up by...

hello everybody.. I'm new member of this forum.. i would like to know what kind of mathematics knowledge is required to understand the mathematics of particle physics? because, i can't understand any math done in classical physics, particle pysics. i interpret particle physics as the study of...

[SOLVED] Particle Physics, perhaps a classification problem Homework Statement How are the classes of particles classified? The Attempt at a Solution Classes of particles should be bosons, leptons, hadrons and baryons. First, I had the idea that the particles are classified according to...

Homework Statement Hi 1) I read the following article: http://pdg.lbl.gov/2005/reviews/passagerpp.pdf On page 12 of the .pdf there is a figure, figure 27.8, which shows how a charged particle deviates from it's path when scattered by the Coulomb force that comes from the nuclei of the matter...

I'm following An introduction to the Standard Model of Particle Physics. Are there any solutions to the problems? Is there a better book to follow? Would appreciate, tx. JP

Couple of spicy questions: 1. If we new particles position to 99.9999...% or 100%, could the particle move at any speed including speed of light or even faster? 2. If a particle would have probability cloud 1 light year wide and we measured and found a particle at one end and few seconds...

if i read griffiths particle physics book will I have enough knowledge of the subject material to start reading peskin and schroeder's qft book or will I still have to learn graduate mechanics and electrodynamics first before starting on that. If I do need to look at graduate mechanics and...

Hi, so I am currently an ug, and I've been offered positions to do particle physics research. The thing that is turning me off is that it's mostly computational work in C++. I don't know how much i'll enjoy working at the computer all day, but the idea of studying what makes up matter is...

at what level is griffiths particle physics book at, what does it expect you to know as a prerequisite?

Yes, I know I'm sad, but anyone with a knowledge of particle physics might find this funny.

Homework Statement A hadron has the quark content \ u \ d^- .Find the baryaon number,charge,spin and strangeness of this hadron.Can you identify this hadron? Homework Equations The Attempt at a Solution baryon number=(1/3)+(-1/3)=0 [u is particle but d bar is antiparticle] charge=...

Homework Statement Consider the combination of an electron with positron(I) and an electron with proton(II).The possible processes are: (i)formation in positronium in (I) (ii)formation in Hydrogen ataom in (II) (iii)annihilation of each other and gamma emission in (I) and (II) both...

I saw a recent question submitted where the person was seeking answers to particle physics due to the debilatating illness of OCD (obsessive compulsive disorder). I wondered whether somebody could answer this question in relation to airborne particles. In for example an work/office...

Quantum field theory or particle physics what first? Hi at present I am confused whether i should try obtining a firm conceptual understanding of QFT before jumping to particle physics or whether aa very brief overview of QFT is enough ?

My first post! Bear with me here - I'm a weekend warrior of particle physics and am just learning because it amazes me. In my journey through nuclear fusion and quantum theory, I first learned that our sun isn't big enough to overcome the Coulomb barrier between two protons necessary to...

Homework Statement Tertiary neutrino and muon beams can be formed using pion -> muon + neutrino decays from a high intensity, high energy secondary pion beam. Consider a secondary pion beam of 100 GeV/c momentum and assume that the neutrinos have a mass of a few eV. Within what angular cone...

I have this weird question where the thickness of the material is given in \frac{grams}{cm^2}. And it's not wrong. What does it mean ?

On this forum, quantum field theory (QFT) is a part of this subforum (Quantum Physics), while particle physics is a subject of another forum. These two topics - QFT and particle physics - are clearly separated. On the other hand, most textbooks on QFT are also textbooks on particle physics...

I'll be starting my PhD this fall, and I intend on entering the field of Theoretical Particle Physics. I was just wondering what I could do to get a head start in the next two months that would help me secure some positions for research within the school. I figure I'd need to pick up a book on...

I'm starting an MSc in theoretical physics this October, and at the moment I'm considering specialising in Condensed Matter or Particle Physics, both of which look quite interesting. I was wondering which one had better career prospects. I suspect it's easier to get a well paid research job in...

I forget the problem exactly but the general solution is good. I believe it was a neutral pion decaying into two photons I don't know the numbers but I'm given momentum and it's gigantic, some GeV, opposed to the wussy pion mass so it's way relativistic I could do the first part easy, it...

I attended a string theory lecture this afternoon at the Joint Particle Physics 2006 meeting in Hawaii. One of the string theory parallel lectures caught my eye: Can string theory make predictions for particle physics? Washington Taylor, MIT The appearance in string theory of a wide range...

Book question -- Nuclear and Particle Physics Has anyone out there read BR Martin's new book: "Nuclear and Particle Physics, An introduction" ?? There is no review in Amazon and I was wondering if it is any good?

Hi all, I'm a rising sophomore in college and intern at SLAC. I'm trying to pick up a little bit more of a background in particle physics so I can analyze rare B decays. I've read a few books that have covered particle physics, but I've just picked up the flavor of it (no pun intended). I'm...

With any luck, sometime soon you can read this paper on the arXiv: Aristide Baratin and Laurent Freidel Hidden quantum gravity in 4d Feynman diagrams: emergence of spin foams The idea is that any ordinary quantum field theory in 4d Minkowski spacetime can be reformulated as a spin foam...

Need "particle physics" Refrence hi:smile: actually , i am looking for a good book that i could down load freely throw the internet . i am studying physics at Damascus univ , Syria >>> thanks

Anyone know of any specific colleges that offer degrees in one or both? I haven't seen many with degrees in Particle Physics. Thanks!

I heard from a particle physics lecture that no one (till now) knows what charge is. We know the interactions of things with charges and more or less its connections with other things, e.g. through electrodynamics, but no one can say what charge is. It is the same with time. I think something...

group theory is an integral part of particle physics and one needs a good understanding of this before one switches on to reading particle phy ...please give me a good reference for this ... i m new to both group theory and particle physics ...thosugh i 've read about the historical evolutions...

Here's the problem: " A particle is in its first excited state with energy Ea, before it decays to its ground state with energy Eg by emitting a photon with an energy hbar*omega (omega = 2Pi*frequency) Why will the photon energy be smaller than DE= Ea - E? Show that: hbar*omega = DE...

What's the best particle physics book for a bigginer? Thanks.

Im wondering if anyone could help me on what math to study for particle physics. So far I have taught myself calculus (differential calc through vector analysis), differential equations (ordinary and partial), and I am currently studying linear algebra, and abstract algebra. I really want to...

What technologies can be considered as offsprings of particle physics? (both everyday-life technologies and others).

Did I say Particle Physics? I shouldn't have said that. I don't know much about it. But still, what I came upto recently was this :- I read somewhere that unstable nuclides can disintegrate in several ways, beta decay and positron decay being two of them. In beta decay, a neutron gets...

like the title thanks

1) What percentage of incident photon radiation passes through 5 mm of material whose absorption coefficient is 0.7 mm^-1? What is an absorption length? I am lost here. Any input ...some mathematical formula for the absoprtion coefficient...would be a great help to me. 2) Why is the mean...
