Abstract

The process $\Lambda_b \rightarrow \Lambda_c \ell^- \bar{\nu}_\ell$ serves as a tool for exploring new physics, with contributions from scalar, vector, and tensor hadronic currents in various models. These form factors are derived from the quark model or lattice QCD. This work introduces a C-code for efficiently reading lattice QCD form factors for these currents, significantly outperforming a previous Mathematica-based approach, with a speed improvement of over 64 times per data point. The code, available on GitHub $(https://github.com/darkfiresmith96/Lattice_QCD)$, also features a web interface for user inputs.
