Current, Pion and Photon Transitions between Heavy Baryons

I discuss the structure of current-induced bottom baryon to charm baryon transitions, and the structure of pion and photon transitions between heavy charm or bottom baryons in the Heavy Quark Symmetry limit as $m_Q\rightarrow\infty$. The emphasis is on the structural similarity of the Heavy Quark Symmetry predictions for the three types of transitions. The discussion involves the ground state $s$-wave heavy baryons as well as the excited $p$-wave heavy baryon states. Using a constituent quark model picture for the light diquark system with an underlying $SU(2N_f)\otimes O(3)$ symmetry one arrives at a number of new predictions that go beyond the Heavy Quark Symmetry predictions.
