Type: Parallel Session: QCD and hadron structure-B8
The axial f.f. is a fundamental property of the nucleon and a key ingredient of neutrino-nucleon cross sections. We have calculated this f.f. in relativistic ChPT at leading and next to leading one-loop orders, assessing the impact of truncation in the determination of LECs from recent LQCD results. The explicit Delta(1232) is crucial to reconcile the light-quark mass dependence of the axial charg ... More

We study Semileptonic $B_s$-meson decay ($B_s\rightarrow$ $K$ $l^+\nu_l$) using Covariant Confined Quark Model (CCQM) which has built-in infrared confinement. The transition form factors are calculated using CCQM in entire range of physical momentum transfer. They can be further utilized to compute the branching fractions of $B_s$ meson. Our preliminary results for form factors $f_+ (0)$ and \$A_+ ... More
