ABSTRACT: In high energy physics, form factor is a function that describes the internal structure of a composite particle. It serves as a mathematical tool to model how a particle interacts with another particle, based on its internal distribution of charge or other properties. Consequently, form factors play a crucial role in hadronic decays. However, reading form factor data and implementing it in the numerical calculations of the hadronic decays and interactions can significantly slow down the computational performance. This paper presents a comparative study between two computational approaches: the transitional tool Mathematica and a custom C-code designed to read and implement form factors in numerical calculations for any hadronic decay or interaction. To test the performance of the C-code, we use the decay channel

as a case study, comparing the computational speed of Mathematica and the C-code in calculating the differential decay rate for this process. The results demonstrate that the C-code is over 64 times faster per data point than Mathematica. The C-code is available on GitHub (https://github.com/darkfiresmith96/Lattice_QCD). We also present a web interface for user input, enhancing accessibility and ease of use.
