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 …

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 …

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 …

Is there anything smaller than a quark? So far we have just discussed protons, neutrons, and electrons in class, so I am just curious.

Dec 31, 2023 · In nuclear physics, while studying gamma decay (Nuclear physics, Roy and Nigam, 1st ed, pp 450) I have read that the parity of photons depends on the type of multipole radiation they …

So atoms are formed from protons and neutrons, which are formed from quarks. But where do these quarks come from? What makes them?
