0031 // Description:Implementation of the Lb2Baryonlnu model
0032 // Class to handle semileptonic Lb -> p l nu decays using the using form factor predictions based on the quark model.  Here baryon can be Lc+, p, Lc*+, N*+.
0033 // Description: Routine to implement Lb->N*+ l nu semileptonic decays using form factor predictions based on the quark model.  The form factors are from W. Roberts, M. Pervin, S. Chapstick, (2011). arXiv:nucl-th/0503030v1.  The model can be used for decays to all N*+ states with J^{P} = 1/2^{+}, 1/2^{-}, 3/2^{+}, 3/2^{-} and, in addition, decays to p, Lc+, Lc(2593)+, Lc(2625)+
