abstract
We present the C++ code BSMPT v2 which is an extension of the previous code BSMPT for the calculation of the strength of the electroweak phase transition in extended Higgs sectors. The new version BSMPT v2 includes the features of BSMPT and extends the already implemented models (the 2-Higgs-Doublet model (2HDM) in its CP-conserving and CP-violating versions and the Next-to-2HDM) by the Complex Singlet Extension of the Standard Model (CxSM). The major upgrade is the implementation of the computation of the baryon asymmetry of the Universe (at present for the C2HDM) in two different approximation, called the FH and the VIA approach. Furthermore, the possibility of varying the renormalisation scale in the loop-corrected effective potential has been added. These changes and further smaller modifications are described in this manual. Additionally, a detailed explanation of the procedure for the implementation of new models is given, which has also changed with respect to the previous version.

The cS2HDM unifies a pseudo-Nambu-Goldstone dark matter candidate with electroweak baryogenesis in a two-Higgs-doublet plus complex singlet setup, featuring naturally suppressed DM-nucleon scattering and CP-violating Higgs interactions under flavour alignment.
The Aligned 2HDM supports strong first-order electroweak phase transitions that yield LISA-detectable gravitational waves together with LHC-accessible signals from additional neutral and charged Higgs states.
New BSMPT implementation of baryon asymmetry computation using WKB transport equations with moment truncations and VEV profile solving, validated in the C2HDM with uncertainty and GW interplay analysis.
