Recoupling matrix elements and decay
arXiv:hep-ph/0602248 · doi:10.1007/BF01574179
Abstract
Recoupling matrix elements are evaluated, in the harmonic oscillator approximation, for all possible angular and radial excitations in processes where quarks recombine. A diagrammatic representation is given. Their use is demonstrated in calculating the transition potential for rho to two pions in a pair creation model.
