G. Belanger, Neil D. Christensen, A. Pukhov, A. Semenov
TL;DR
SLHAplus is a library designed to simplify the implementation of new physics models in computational tools for particle physics, supporting model input, diagonalization, and integration with popular software.
Contribution
It introduces a versatile library with SLHA reading and diagonalization functions, compatible with CalcHEP, micrOMEGAs, LanHEP, and FeynRules, enhancing model implementation efficiency.
Findings
Facilitates easier implementation of new models in physics codes.
Supports multiple software tools for model analysis.
Streamlines the process of extending the standard model.
Abstract
We provide a library to facilitate the implementation of new models in codes such as matrix element and event generators or codes for computing dark matter observables. The library contains a SLHA reader routine as well as diagonalisation routines. This library is available in CalcHEP and micrOMEGAs. The implementation of models based on this library is supported by LanHEP and FeynRules.
