The phenomenology of Axion Relic Pockets
Wafaa Khater, M. C. David Marsh, Charalampos Nikolis
Axion relic pockets are phase-transition remnants consisting of regions of false vacuum stabilised from collapse by a hot axion gas. Axion relic pockets can comprise dark matter, b…
CP violation in H^\pm \to W^\pm Z: A physical approach for the 2HDM
Wafaa Khater, Odd Magne Ogreid, Per Osland +1
We investigate CP violation in the process H^\pm \to W^\pm Z within the framework of the two-Higgs-Doublet model (2HDM). Amplitudes are expressed transparently in terms of physical…
Tree-level unitarity in Higgs inflation in the metric and the Palatini formulation
Asuka Ito, Wafaa Khater, Syksy Rasanen
We calculate the tree-level amplitudes for electrically neutral scattering for the Standard Model Higgs doublet non-minimally coupled to the Ricci scalar. We consider both…
Dark matter in three-Higgs-doublet models with symmetry
W. Khater, A. Kunčinas, O. M. Ogreid +2
Models with two or more scalar doublets with discrete or global symmetries can have vacua with vanishing vacuum expectation values in the bases where symmetries are imposed. If a s…
Prospects for charged Higgs searches at the LHC
A. G. Akeroyd, M. Aoki, A. Arhrib +25
The goal of this report is to summarize the current situation and discuss possible search strategies for charged scalars, in non-supersymmetric extensions of the Standard Model at…
Consistency of the Two Higgs Doublet Model and CP violation in top production at the LHC
Abdul Wahab El Kaffas, Wafaa Khater, Odd Magne Ogreid +1
It is important to provide guidance on whether CP violation may be measurable in top-quark production at the Large Hadron Collider. The present work extends an earlier analysis of…
