Results from LHCb in charmless $b$-baryon decay

Since mostly unexplored, the heavy baryon sector is an interesting field where to search for new physics effects. Recent LHCb results in b -baryon decays to charmless final states are presented based on p p collision data collected in 2011 and 2012 at centre-of-mass energies of √ s = 7 TeV and 8 TeV, respectively. The total integrated luminosity collected is 3.0 fb − 1 . New decays of b -baryons are presented and preliminary studies of CP violation are performed. The first evidence of CP violation in baryons is provided in Λ 0 b → p π − π + π − decays by means of the triple-product correlation technique. All the other presented CP asymmetries are compatible with zero.
