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…
The trap in the early Universe: impact on the interplay between gravitational waves and LHC physics in the 2HDM
Thomas Biekötter, Sven Heinemeyer, José Miguel No +2
We analyze the thermal history of the 2HDM and determine the parameter regions featuring a first-order electroweak phase transition (FOEWPT) and also much less studied phenomena li…
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-…
Interdependence of the new "MUON G-2" Result and the -Boson Mass
E. Bagnaschi, M. Chakraborti, S. Heinemeyer +2
The electroweak (EW) sector of the Minimal Supersymmetric extension of the Standard Model (MSSM), assuming the lightest neutralino as Dark Matter (DM) candidate, can account for a…
Excesses in the low-mass Higgs-boson search and the W-boson mass measurement
Thomas Biekötter, Sven Heinemeyer, Georg Weiglein
The CDF collaboration recently reported a measurement of the -bosos mass, , showing a large positive deviation from the Standard Model (SM) prediction. The question arises…
