Description

In this poster we present the results of a lattice QCD comput-ation at $N_f = 2$ for the processes $B_{s} \rightarrow D_{s}^{(\star)}$, and their form factors parametrization in the heavy quark limit $\mathcal{G}$, $h_{A_{1}}$, $h_{A_{2}}$ and $h_{A_{3}}$. This study is in line with the research of new physics in the B sector, which is motivated by recent tensions reported in lepton flavor universality tests, the so-called B anomalies. Our strategy to deal with systematic effects on lattice calculations reveals promising for forthcoming steps of our work performed with simulations at the physical point.
