| 英文摘要 | The decay of Lambda(b) --> Sigma(c)((*)) pi/<(nu)over bar> processes is calculated in the framework of heavy baryon chiral perturbation theory with the help of the 1/N-c expansion. The decay rate distributions over nu . nu' where nu and nu' are the four-vector velocities of Lambda(b) and Sigma(c)((*)), respectively, and over the pion and lepton energies, are given. The decay branching ratios amount to about 1.21(0.971)% for Lambda(b)-->Sigma(c) pi/<(nu)over bar> and 0.798(0.640)% for Lambda(b)-->Sigma(c)* pi/<(nu)over bar> by using the baryonic Isgur-Wise function predicted by QCD sum rules (large N-c QCD). |
