| 英文摘要 | Within the framework of HQET, Lambda(b) -> Lambda(c)tau(nu) over bar (tau) and Omega(b) -> Omega(()(c)*()) tau(nu) over bar tau weak decays are studied to the order of 1/m(c) and 1/m(b). Helicity amplitudes are written down. Relevant Isgur-Wise functions given by QCD sum rule and large N-c methods are applied in the numerical analysis. The baryonic R-ratios R(Lambda(c)) and R(Omega(()(c)*())) are obtained. (C) 2020 The Author(s). Published by Elsevier B.V. |
