WebJ/psi particle, type of meson consisting of a charmed quark and a charmed antiquark. It has a mass of 3.1 GeV/c2, which is about 3.5 times larger than the mass of a proton. The particle was first detected in 1974 by two groups of American physicists working independently of each other, one headed by Burton Richter at SLAC (Stanford Linear … WebThe B-meson contains a b-quarkand the least massive variety has a mass about 5.6 times that of a proton. The table summarizes the properties of the B variety which contains the b-quark along with an up or down quark. The more exotic varieties Bsand Bccontain the b-quark along with a strange or charm quark respectively.
