Cosmology of Multi-Singlet-Scalar Extensions of the Standard Model
Aleksandra Drozd, Bohdan Grzadkowski, Jose Wudka
An extension of the Standard Model by extra scalar singlets was considered. Theoretical (unitarity, vacuum stability, triviality) and cosmological (dark matter relic abundance, dir…
Constraints on Two-Component Dark Matter
Subhaditya Bhattacharya, Aleksandra Drozd, Bohdan Grzadkowski +1
We study 'Higgs Portal' 2-component Dark Matter scenario with two interacting cold Dark Matter (DM) candidates: a neutral scalar singlet () and a neutral Majorana fermion ().…
Diagnosing CP properties of the 2HDM
B. Grzadkowski, O. M. Ogreid, P. Osland
We have investigated a Two-Higgs-Doublet Model (2HDM), focusing on CP violation. Various scenarios with spontaneous and explicit breaking of CP have been considered. Some features…
Two-Component Dark Matter
Subhaditya Bhattacharya, Aleksandra Drozd, Bohdan Grzadkowski +1
We study an extension of the Standard Model (SM) with two interacting cold Dark Matter (DM) candidates: a neutral Majorana fermion () and a neutral scalar singlet (). The sca…
