A Deep Dive into Baryon Asymmetry -- the C2HDM

Margarete Mühlleitner, Johann Plotnikov, Rui Santos +1

In this paper, we present our new implementation of the computation of the baryon asymmetry in the code BSMPT. It is based on the WKB ansatz generalizing the transport equations to…

NMSSMScanner: Efficient Scans in the NMSSM Parameter Space Proof of Concept

Rafael Boto, Thi Nhung Dao, Felix Egle +4

We present the first version of the new scanning tool NMSSMScanner that allows to perform efficient scans in the complex multi-parameter space of the Next-to-Minimal Supersymmetric…

Reassessing CP Violation in the C2HDM with Machine Learning

Rafael Boto, Karim Elyaouti, Duarte Fontes +5

We provide a study of the parameter space of the complex 2-Higgs Doublet Model (C2HDM), focusing on signs of large CP-violating couplings of the 125 GeV Higgs boson with the fermio…

BSMPT v3 A Tool for Phase Transitions and Primordial Gravitational Waves in Extended Higgs Sectors

Philipp Basler, Lisa Biermann, Margarete Mühlleitner +3

Strong first-order phase transitions (SFOPT) during the evolution of the Higgs potential in the early universe not only allow for the dynamical generation of the observed matter-an…

Distorting the Top Resonance with Effective Interactions

Felix Egle, Christoph Englert, Margarete Mühlleitner +1

Interference effects in effective field theory (EFT) analyses can significantly distort sensitivity expectations, leaving subtle yet distinct signatures in the reconstruction of fi…

Double and Triple Higgs Production to probe the Electroweak Phase Transition

Lisa Biermann, Christoph Borschensky, Christoph Englert +2

The production of three Higgs bosons could be a stretch goal for the LHC and a strategic case for future colliders. In this work, we analyse the phenomenological prospects of (neut…
