One form of this interaction is governed by the CKM matrix. Because they decay by this interaction, charged pions have long lifetimes. Having charged- and neutral-current interactions, this force allows flavor change and, as discovered by Yang and Lee and Cronin and Fitch, breaks both P and CP symmetry. Research about this force garnered the 1979 Nobel Prize in Physics for Glashow, Salam, and Weinberg, who unified it with the electromagnetic force. It is mediated by heavy gauge bosons named W an

Research about this force garnered the 1979 Nobel Prize in Physics for Glashow, Salam, and Weinberg, who unified it with the electromagnetic force. It is mediated by heavy gauge bosons named W and Z. FTP, name this short-ranged interaction with a very small coupling constant.
