Standard Model of electroweak interactions of particle physics, the weak hypercharge is a quantum number relating the electric charge and the third component
In particle physics, the hypercharge (a portmanteau of hyperonic and charge) Y of a particle is a quantum number conserved under the strong interaction
a quantum number called weak hypercharge, YW, which is −1 for all left-handed leptons. Weak isospin and weak hypercharge are gauged in the Standard Model
The J/ψ (J/psi) meson /ˈdʒeɪ ˈsaɪ ˈmiːzɒn/ is a subatomic particle, a flavor-neutral meson consisting of a charm quark and a charm antiquark. Mesons formed
