论文摘要
使用重型夸克扩展到$ {\ cal o}（1/m_b^3）$，以$α_s$ $α_s$的领先顺序研究，对纳入美容重子的包含半衰减。参考了$λ_b$，检查了两极分化的衰减重子。标准模型的延伸有效的哈密顿式诱导$ b \ to u \ ell {\barν} _ \ ell $ transitions（$ u = u = u = u，\，\，\，c $和$ \ ell = e，\ \ \，\，\，μ，\，τ$）被认为是D = 6 = 6 = 6 = 6 = 6 = 6 = 6的半蛋白质的左手中的左手中的左手手术。描述了新操作员在几个可观察物中的影响。
Inclusive semileptonic decays of beauty baryons are studied using the heavy quark expansion to ${\cal O}(1/m_b^3)$, at leading order in $α_s$. The case of a polarized decaying baryon is examined, with reference to $Λ_b$. An extension of the Standard Model effective Hamiltonian inducing $b \to U \ell {\bar ν}_ \ell$ transitions ($U=u,\,c$ and $\ell=e,\,μ,\,τ$) is considered, which comprises the full set of D=6 semileptonic operators with left-handed neutrinos. The effects of the new operators in several observables are described.
