We also separate the cases where (a) it may be invisible but not a dark matter candidate, or (b) it may decay showing a displaced vertex.

WebThe D Meson is the lightest particle which contains a charm quark, and therefore is a good example for the study of decay by quark transformation by the weak interaction. An interesting example of a particle interaction which involves the D meson was observed in a bubble chamber at SLAC in 1982 (K. Abe et al., Phys. Rev. Lett. 48,1526 (1982)).
