单词 hypercharge
释义 hypercharge
A quantized property of baryons (see elementary particles) that provides a formal method of accounting for the nonoccurrence of certain expected decays by means of the strong interaction (see fundamental interactions). Hypercharge is in some respects analogous to electric charge but it is not conserved in weak interactions. Nucleons have a hypercharge of +1, and the pion has a value of 0. Quarks would be expected to have fractional hypercharges
