Hadronic production of double charmed baryons with excited diquark

Abstract We discuss the prospects of the observation of double heavy baryons Ξ cc , Ω cc with excited diquark (S and P excitations) in experiments at LHC. P-wave excitations of a diquark in double charmed baryons are supposed to be quite narrow since their decay into the ground state is highly suppressed. Relative yields of S-wave and P-wave excitations have been estimated within pQCD for the LHCb kinematics.
