Invariant mass

The invariant mass, rest mass, intrinsic mass, proper mass, or in the case of bound systems simply mass, is the portion of the total mass of an object or system of objects that is independent of the overall motion of the system.

J/psi meson

The (J/psi) meson or psion is a subatomic particle, a flavor-neutral meson consisting of a charm quark and a charm antiquark.

Kaon

In particle physics, a kaon, also called a K meson and denoted,The positively charged kaon used to be called τ+ and θ+, as it was supposed to be two different particles until the 1960s.

Momentum transfer

In particle physics, wave mechanics and optics, momentum transfer is the amount of momentum that one particle gives to another particle.

Phi meson

In particle physics, the phi meson or meson is a vector meson formed of a strange quark and a strange antiquark.

Quantum chromodynamics

In theoretical physics, quantum chromodynamics (QCD) is the theory of the strong interaction between quarks and gluons, the fundamental particles that make up composite hadrons such as the proton, neutron and pion.

Quarkonium

In particle physics, quarkonium (from quark and -onium, pl. quarkonia) designates a flavorless meson whose constituents are a heavy quark and its own antiquark, making it a neutral particle.

Strong interaction

In particle physics, the strong interaction is the mechanism responsible for the strong nuclear force (also called the strong force or nuclear strong force), and is one of the four known fundamental interactions, with the others being electromagnetism, the weak interaction, and gravitation.
