Theoretical concepts and measurement prospects for BSM trilinear couplings: a case study for scalar top quarks
Henning Bahl, Johannes Braathen, Georg Weiglein
After the possible discovery of new heavy particles at the LHC, it will be crucial to determine the properties and the underlying physics of the new states. In this work, we focus…
HiggsTools: BSM scalar phenomenology with new versions of HiggsBounds and HiggsSignals
Henning Bahl, Thomas Biekötter, Sven Heinemeyer +4
The codes HiggsBounds and HiggsSignals compare model predictions of BSM models with extended scalar sectors to searches for additional scalars and to measurements of the detected H…
New Tools for Dissecting the General 2HDM
Henning Bahl, Marcela Carena, Nina M. Coyle +2
Two Higgs doublet models (2HDM) provide the low energy effective field theory (EFT) description in many well motivated extensions of the Standard Model. It is therefore relevant to…
Report of the Topical Group on Higgs Physics for Snowmass 2021: The Case for Precision Higgs Physics
Sally Dawson, Patrick Meade, Isobel Ojalvo +78
A future Higgs Factory will provide improved precision on measurements of Higgs couplings beyond those obtained by the LHC, and will enable a broad range of investigations across t…
External-leg corrections as an origin of large logarithms
Henning Bahl, Johannes Braathen, Georg Weiglein
Obtaining precise theoretical predictions for both production and decay processes of heavy new particles is of great importance to constrain the allowed parameter spaces of Beyond-…
Tripling down on the boson mass
Henning Bahl, Wen Han Chiu, Christina Gao +2
A new precision measurement of the boson mass has been announced by the CDF collaboration, which strongly deviates from the Standard Model prediction. In this article, we study…
Snowmass White Paper: Prospects of CP-violation measurements with the Higgs boson at future experiments
A. V. Gritsan, H. Bahl, R. K. Barman +15
The search for CP violation in interactions of the Higgs boson with either fermions or bosons provides attractive reference measurements in the Particle Physics Community Planning…
New physics effects on the -boson mass from a doublet extension of the SM Higgs sector
Henning Bahl, Johannes Braathen, Georg Weiglein
Recently, the CDF collaboration has reported a new precision measurement of the -boson mass, , showing a large deviation from the value predicted by the Standard Model (SM)…
Constraining the CP structure of Higgs-fermion couplings with a global LHC fit, the electron EDM and baryogenesis
Henning Bahl, Elina Fuchs, Sven Heinemeyer +5
CP violation in the Higgs couplings to fermions is an intriguing, but not yet extensively explored possibility. We use inclusive and differential LHC Higgs boson measurements to fi…
New constraints on extended Higgs sectors from the trilinear Higgs coupling
Henning Bahl, Johannes Braathen, Georg Weiglein
The trilinear Higgs coupling is crucial for determining the structure of the Higgs potential and for probing possible effects of physics beyond the Standard Model (SM). F…
