pions

Physique; La physique des particules

Pions are the lightest mesons. They are composed of up quarks, down quarks, and their anti-quark counterparts. Pions of charge +1, -1, and 0 are denoted pi + , pi - , and pi 0 , respectively.

positron

Physique; La physique des particules

the anti-matter partner of the electron. It is identical in all respects to an electron, but it has positive charge.

One of the constituents of atoms. Along with the neutron, the proton can be found in the nuclei (centers) or atoms. Protons have a positive electric charge, and are composed of two up quarks and a ...

chromodynamique quantique (QCD)

Physique; La physique des particules

The theory of the strong interaction. It describes the exchange of gluons between quarks.

dimensions quantiques

Physique; La physique des particules

As yet undiscovered dimensions of space-time that convert force particles to matter particles and vice versa. Such dimensions are predicted in theories with supersymmetry or superstrings. The pair of ...

gravité quantique

Physique; La physique des particules

At very small distances, the principles of quantum mechanics are necessary to accurately describe physical phenomena. Developing a theory that incorporates both the principles of quantum mechanics ...
