Hello; I'am asking about the best textbook or refrence in particle & high energy physics ?

Ok. So I literally just created this account, but I need to ask you all something. I'm a junior in undergraduate college. I am pursuing a double major in English-Literature, and Philosophy. I have always been interested in physics, specifically astronomy, astrophysics, particle physics, etc...

I'm a senior undergrad and will be applying to grad school soon. The field I'm interested in is experimental high-energy physics. There are already about six schools I'm looking at applying to, but I'm wondering if anyone has any advice about possible safety schools. My overall GPA is about...

Hello everyone. After some time of using the internet for entertainment purposes, I decided it would be good to actually learn from it. I saw Sagan's Cosmos for the first time, and got very hooked up with Particle Physics. I'm trying to understand but I'm having trouble getting the hang of...

Are there any areas of Chemistry that are dedicated to the study of elementary particles e.g.the Standard Model?

If a Meson is a Hadron that contains a Quark and an Anti-Quark which are both Fermions then why are Mesons a type of Gauge Boson?

Hi, I'm Marc. I'm 14, from the UK and I love Particle Physics and Nuclear Physics. I was just wondering about how much Maths and what areas of Maths I would need to accumulate the knowledge for, in order to do A-level and eventually University Physics, specifically Particle Physics. Could...

Electronics , Nuclear and Particle physics , which one has the most importance today life?

Is there a version of Mach's Principle in Particle Physics? If yes, does it hold true? A version could possibly look as follows: certain properties of a particle can be attributed entirely to the existence of other particles ( for instance, can the charge of a particle be attributed to...

Hi everybody, Just recently I got an epiphany (or a crazy idea, I don't really know which one) that I want to pursue a masters, with the emphasis of skipping my masters half way through in order to upgrade to a doctorate. The program that I am in (B.Sc in Medical Physics, 2nd year) does not...

True Background-Independent String Theory/Particle Physics Lee Smolin mentions in Trouble with Physics: "... it is not enough to have a theory with gravitons made from strings wiggling in space. We need a theory about what makes up space, a background-independent theory. As described...

And are reactions in particle physics reversible at all? If so, why don't we ever see Gibbs free energy used in particle physics equations?

Hello! I have difficulty trying with the interpretation of: (\frac{1}{2}) \otimes (\frac{1}{2}) \otimes (\frac{1}{2}) = (\frac{3}{2}) \otimes (\frac{1}{2}) \otimes (\frac{1}{2}) If I´m right this is the SU(2) irrep for isospin but what does this mean? Proton = Neutron?

Special Relativity is just a special case where spacetime is flat and fixed. Meaning it is not really a correct picture of reality because nature chooses curved spacetime that is background independent. So quantum particles shouldn't be occurring in a flat fixed background but a dynamic...

What is the difference between particle physics and nuclear physics? Two areas is often treated as a single region as "nuclear and particle physics". Some author of paper, however, distinguish sharply between the two regions. I want to know the boundaries of particle physics and nuclear physics.
