SPheno 3.1: extensions including flavour, CP-phases and models beyond the MSSM

TL;DR

SPheno 3.1 introduces comprehensive extensions to the spectrum generator, enabling detailed calculations of supersymmetric particle masses, flavour mixing, CP-phases, and low energy observables, including models beyond the MSSM.

Contribution

The paper presents new features in SPheno 3.1 for calculating supersymmetric spectra with full flavour and CP-violation, and supports models beyond the MSSM.

Findings

Complete 1-loop mass calculations with flavour and CP phases

Implementation of seesaw models and low energy observables

Extended SUSY Les Houches Accord compatibility

Abstract

We describe recent extensions of the program SPheno including flavour aspects, CP-phases, R-parity violation and low energy observables. In case of flavour mixing all masses of supersymmetric particles are calculated including the complete flavour structure and all possible CP-phases at the 1-loop level. We give details on implemented seesaw models, low energy observables and the corresponding extension of the SUSY Les Houches Accord. Moreover, we comment on the possiblities to include MSSM extensions in SPheno.
