Jan 11, 2012 · What exactly is $p_T$? Is it simply momentum, but with the component parallel to the main beam projected off? Also, why is $p_T$, as opposed to $p$, an important characteristic of a …

Chirality is a fundamental property of a particle; particles which differ in terms of chirality can be viewed as an entirely different type of particle. It refers to how a particle's quantum mechanical wave function …

I know classical physics, quantum mechanics, special relativity, and basic nuclear physics. I would like to get into some particle physics. Where can I find a good introduction? It might be usefu...

In that configuration, the only way to reduce the field energy is to bring the charges closer together, so there is a force in that direction, i.e., of each particle directly toward the other. The energy density of …

8 Particle physics has a set of elementary particles , some of which have zero mass. In this table the general public has heard of the electron and maybe the photon. The mass of the electron has been …

So that decaying particle has a decay constant which is the sum of the decay constants for all of the possible modes of decay. At the moment of decay the decaying particle chooses one particular mode …

Sep 16, 2022 · See this answer which is somewhat technical (undergraduate-physics-major level). When you add quantum mechanics, you get particle-like behavior of the field, and each particle …

Mar 26, 2021 · For single-particle quantities the usual convention is to use lower-case letters and symbols. It's probably fair to say that term symbols are most commonly used in atomic physics, and …

From my understanding of the standard model, I understand that there are 19 or 20 free parameters that we need to put in by hand as, and I'm guessing here, there is as yet no theoretical basis for

This was a statement given in my class: " Strangeness is conserved in the strong and electromagnetic interactions, but not in a weak interaction " But could someone please tell me how we differentiate …
