Description

Determining the form factors for Semileptonic Decay processes on the lattice is essential for understanding CKM matrix elements. Some of these decay processes are $\Sigma_b \rightarrow \Sigma_c$, $\Omega_b \rightarrow \Omega_c$, and $\Xi_c \rightarrow \Xi$, the later one is observed in experiments like Belle and ALICE. Meson decays are extensively studied on the lattice, however baryon decays on the lattice are still under development. In this project, we want to study the Form Factors of the aforementioned decays where we use Relativistic Heavy Quark Action to simulate the bottom quark, which enables us to treat it relativistically. This approach avoids the disadvantages of NRQCD, which suffers from tuning problem. For the light quark, we use the clover action. This study is conducted on the $16^3 \times 48$ ensembles generated by the MILC collaboration. The necessary steps involve tuning the parameters of RHQ action and calculation of the three-point function, which are depicted in this poster presentation.
