HDECAY: a Program for Higgs Boson Decays in the Standard Model and its Supersymmetric Extension
read the original abstract
We describe the Fortran code HDECAY which calculates the decay widths and the branching ratios of the Standard Model Higgs boson, and of the neutral and charged Higgs particles of the Minimal Supersymmetric extension of the Standard Model. The program is self-contained (with all subroutines included), easy to run, fast and calculates the decay widths and branching ratios according to the current theoretical knowledge.

WIMP-like Dark Matter Without Thermalization At Freeze-Out
Hidden-sector dark matter achieves standard thermal relic abundance via early decoupling with temperature-matched freeze-out, enabling WIMP-like cross sections without late-time thermalization.

Exploring non-equilibrium effects in sequential freeze-in
In a two-scalar dark sector, non-equilibrium phase-space evolution during sequential freeze-in alters the dark matter relic abundance by up to an order of magnitude relative to the standard number-density treatment.

Towards a Unified Framework for Pseudo-Nambu-Goldstone Dark Matter and Electroweak Baryogenesis
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 ...

Intrinsic Properties of Large CP Violation in the Complex Two-Higgs-Doublet Model
Global scans of complex 2HDM show Type-I models maximize gauge CPV near light-Higgs degeneracy with high eEDM, Type-II suppress gauge CPV but permit large Yukawa CPV and low eEDM via cancellations, plus hidden CPV in ...

Search for a resonance decaying into a scalar particle and a Higgs boson in the final state with two bottom quarks and two photons with 199 fb$^{-1}$ of data collected at $\sqrt{s}$=13 and 13.6 TeV with the ATLAS detector
Search for resonant X -> S(bb) H(gamma gamma) production finds no significant excess and sets 95% CL limits on sigma*BR ranging from 9 fb to 0.06 fb over mass ranges 170-1000 GeV for X and 15-500 GeV for S.
