Baryon decays to purely baryonic final states

Abstract The LHCb collaboration has presented first experimental evidence that spin-carrying matter and antimatter differ. The study looked at four-body decays of the $${{\boldsymbol{\Lambda }}}_{{\boldsymbol{b}}}^{{\bf{0}}}$$ Λb0 baryon. Differences in the behaviour of matter and antimatter are ass...
