The Higgs vacuum uplifted: revisiting the electroweak phase transition with a second Higgs doublet

Journal of High Energy Physics, 2017
The existence of a second Higgs doublet in Nature could lead to a cosmological first order electroweak phase transition and explain the origin of the matter-antimatter asymmetry in the Universe.

A potentially detectable gamma-ray line in the Fermi Galactic center excess — in light of one-step cascade annihilations of secluded (vector) dark matter via the Higgs portal

Journal of High Energy Physics, 2020
We show the presence of a potentially detectable gamma-ray line in the Fermi Galactic center excess in light of the secluded (vector) dark matter (DM) model in which the hidden scalar, nearly degenerate with DM in mass, mediates the interaction of the ...

Scalar electroweak multiplet dark matter

Journal of High Energy Physics, 2019
We revisit the theory and phenomenology of scalar electroweak multiplet thermal dark matter. We derive the most general, renormalizable scalar potential, assuming the presence of the Standard Model Higgs doublet, H, and an electroweak multiplet Φ of ...

Scope of self-interacting thermal WIMPs in a minimal U(1) D extension and its future prospects

Journal of High Energy Physics, 2019
In this work we have considered a minimal extension of Standard Model by a local U(1) gauge group in order to accommodate a stable (fermionic) Dark Matter (DM) candidate. We have focussed on parameter regions where DM possesses adequate self-interaction,

Sterile neutrino dark matter in left-right theories

Journal of High Energy Physics, 2020
SU(2) L × SU(2) R gauge symmetry requires three right-handed neutrinos (N i ), one of which, N 1, can be sufficiently stable to be dark matter. In the early universe, W R exchange with the Standard Model thermal bath keeps the right-handed neutrinos in ...

Flavor physics within and beyond the Standard Model [PDF]

, 2010
I review recent progress in theoretical calculations related to the CKM unitarity triangle. After briefly discussing hints for new physics in B_d-B_d-bar mixing and B_s-B_s-bar mixing I present three topics of MSSM flavor physics: First I discuss new tan-

The rare and forbidden: Testing physics beyond the standard model with Mu3e [PDF]

SciPost Physics Proceedings, 2018
The upcoming Mu3e experiment aims to search for the lepton flavour violating decay \boldsymbol{\muposeeemath} with an unprecedented final sensitivity of one signal decay in \boldsymbol{\num{e16}} observed muon decays by making use of an innovative ...

Gravitational tests of electroweak relaxation

Journal of High Energy Physics, 2021
We consider a scenario in which the electroweak scale is stabilized via the relaxion mechanism during inflation, focussing on the case in which the back-reaction potential is generated by the confinement of new strongly interacting vector-like fermions ...

A tale of two portals: testing light, hidden new physics at future e + e − colliders

Journal of High Energy Physics, 2017
We investigate the prospects for producing new, light, hidden states at a future e + e − collider in a Higgsed dark U(1) D model, which we call the Double Dark Portal model. The simultaneous presence of both vector and scalar portal couplings immediately
