Description
In BSM models often many choices for the renormalization scheme (RS) for the BSM particles (masses and mixings) are possible. Several of them lead to numerically unstable results. However, for a given parameter point in a BSM model it is a priori not known which RS leads to stable results, which makes the implementation of higher-order corrections in BSM models into automated codes complicated. We present a new and simple method to test the RS's for BSM parameter points, and to determine which one leads to stable results. This will facilitate the implementation of higher-order corrections to BSM processes into fully automated codes.
