H-COUP: a program for one-loop corrected Higgs boson couplings in non-minimal Higgs sectors
Shinya Kanemura, Mariko Kikuchi, Kodai Sakurai +1
We describe a numerical calculation tool H-COUP written in Fortran, which provides one-loop electroweak corrected vertices for the discovered Higgs boson in various Higgs…
Extracting the mass scale of a second Higgs boson from a deviation in couplings
Simone Blasi, Stefania De Curtis, Kei Yagyu
We investigate the correlation between a possible deviation in the discovered Higgs boson couplings from the Standard Model prediction and the mass scale (…
Radiative corrections to Higgs couplings with weak gauge bosons in custodial multi-Higgs models
Cheng-Wei Chiang, An-Li Kuo, Kei Yagyu
We calculate 1-loop radiative corrections to the and couplings in models with next--to--simplest Higgs sectors satisfying the electroweak parameter equal to 1 at tr…
Gauge invariant one-loop corrections to Higgs boson couplings in non-minimal Higgs models
Shinya Kanemura, Mariko Kikuchi, Kodai Sakurai +1
We comprehensively evaluate renormalized Higgs boson couplings at one-loop level in non-minimal Higgs models such as the Higgs Singlet Model (HSM) and the four types of Two Higgs D…
Muon specific two-Higgs-doublet model
Tomohiro Abe, Ryosuke Sato, Kei Yagyu
We investigate a new type of a two-Higgs-doublet model as a solution of the muon anomaly. We impose a softly-broken symmetry to forbid tree level flavor changing neutra…
Effects of custodial symmetry breaking in the Georgi-Machacek model at high energies
Simone Blasi, Stefania De Curtis, Kei Yagyu
The model proposed by Georgi and Machacek enables the Higgs sector to involve isospin triplet scalar fields while retaining a custodial symmetry in the potential and thus…
