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

September 27, 2011 | W. Porod1 and F. Staub2
The paper discusses recent extensions of the SPHeno program to include flavor aspects, CP-phases, R-parity violation, and low energy observables. The program calculates the masses and couplings of supersymmetric particles in various models, including the MSSM with generation mixing and CP violation, seesaw mechanisms, and MSSM with bilinear R-parity breaking. It also extends decay routines to account for flavor effects and includes a set of low energy observables such as $B$-physics and lepton sector observables. The paper details the implementation of these extensions, including the use of SLHA2 conventions, and provides default values for various flags and error coding. Additionally, it describes the installation and implementation of new models using the SARAH package, and outlines future plans for further improvements and extensions.The paper discusses recent extensions of the SPHeno program to include flavor aspects, CP-phases, R-parity violation, and low energy observables.
