Description
In this poster we present the study of Λ-hyperon to proton transition in Lattice QCD. We use the computed form factors from LQCD, and apply it to a number of problems. For example, we compute the decay rate of the electron semi-leptonic decay, and by combining it with the experimental data we obtain $V_{us}$. Furthermore, we use this decay channel to search for possible physics beyond the Standard Model, such as scalar and tensor interactions. Finally, we apply the same form factors to describe neutrino scattering and compare the predicted cross sections with measurements from several experiments.
