HiggsTools for LHC Run 3 and Beyond
Henning Bahl, Thomas Biekötter, Sven Heinemeyer +2
HiggsTools, including the subpackages HiggsPredictions, HiggsBounds, and HiggsSignals, is a toolbox for Beyond-the-SM (BSM) scalar phenomenology at the LHC. It provides BSM model p…
Precise predictions for trilinear Higgs couplings and Higgs pair production in extended scalar sectors with anyH3 and anyHH
Henning Bahl, Johannes Braathen, Martin Gabelmann +2
A central objective of future collider experiments is to probe the structure of the Higgs potential, which requires access to trilinear scalar couplings, in particular the self-cou…
Complementarity of di-top and four-top searches in interpreting possible signals of new physics
Henning Bahl, Philipp Gadow, Romal Kumar +3
Final states comprising two or more top quarks are important search channels at the Large Hadron Collider for scalar particles predicted in models of physics beyond the Standard Mo…
Assessing uncertainties in the determination of the trilinear Higgs self-coupling from single-Higgs observables
Henning Bahl, Philip Bechtle, Johannes Braathen +4
Circular colliders operating at energies below the di-Higgs production threshold can provide information on the trilinear Higgs self-coupling via its loop c…
Classifying the CP properties of the ggH coupling in H+2j production
Henning Bahl, Elina Fuchs, Marc Hannig +1
The Higgs-gluon interaction is crucial for LHC phenomenology. To improve the constraints on the CP structure of this coupling, we investigate Higgs production with two jets using m…
Impact of Interference Effects on Higgs-boson Searches in the Di-top Final State at the LHC
Henning Bahl, Romal Kumar, Georg Weiglein
The di-top final state is an important search channel for additional Higgs bosons at the LHC. In this channel, large signal--background interference contributions can strongly dist…
