### Description

In view of the recent discovery of $\Xi_{cc}$ by the LHCb collaboration the study of doubly heavy baryons is becoming relevant. In this work we discuss the prospects of the observation of such states with excited $cc$-diquark (S and P excitations) by the LHCb experiment. P-wave excitations of a diquark in $\Xi_{cc}$ are expected to be quite narrow since their decay into the ground state is suppressed as $\Lambda_{QCD}^2/m_c^2$. The relative yield of S-wave and P-wave excitations for the LHCb kinematics has been estimated as 50% and 5% respectively.
