# 2HDMC — two-Higgs-doublet model calculator

## Description

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We describe version 1.0.6 of the public C++ code 2HDMC, which can be used to perform calculations in a general, CP-conserving, two-Higgs-doublet model (2HDM). The program features simple conversion between different parametrizations of the 2HDM potential, a flexible Yukawa sector specification with choices of different Z_2-symmetries or more general couplings, a decay library including all two-body — and some three-body — decay modes for the Higgs bosons, and the possibility to calculate...
