Abstract
One of the primary goals in hadron physics is to understand the structure, properties and dynamics of strongly interacting hadronic systems. This can be accomplished by employing contemporary analytical approaches, such as chiral effective theory and dispersion relation, and by developing computational techniques. In this talk, I will present how to perform high-order calculations within the framework of relativistic baryon chiral perturbation theory by using extended-on-mass shell scheme. A preliminary Mathematica package will be introduced, which is designed for efficient analytical calculation of loop amplitudes from Feynman rules, performing Passarino-Veltmann reduction and extracting power counting breaking terms. The computations of finite-volume corrections and two-loop chiral amplitudes will be discussed briefly as well.
