Salam Tawfiq, Patrick J. O'Donnel, J. G. Koerner
Abstract
Light-Front quark model spin wave functions are employed to calculate the three independent couplings gΣc Λc π, fΛc1 Σc π and fΛ*c1 Σc π of S-wave to S-wave and P-wave to S-wave one-pion transitions. It is found that gΣc Λc π=6.81 MeV-1, fΛc1 Σc π=1.16 and fΛ*c1 Σc π=0.96 . 10-4 MeV-2. We also predict decay rates for specific strong transitions of charmed baryons.
