Dark Matter through the Higgs portal

G Arcadi, A Djouadi, M Raidal - Physics Reports, 2020 - Elsevier
We review scenarios in which the particles that account for the Dark Matter (DM) in the
Universe interact only through their couplings with the Higgs sector of the theory, the so …

Building and testing models with extended Higgs sectors

IP Ivanov - Progress in Particle and Nuclear Physics, 2017 - Elsevier
Abstract Models with non-minimal Higgs sectors represent a mainstream direction in
theoretical exploration of physics opportunities beyond the Standard Model. Extended scalar …

Search for heavy neutral lepton production in K+ decays to positrons

EC Gil, A Kleimenova, E Minucci, S Padolski, P Petrov… - Physics Letters B, 2020 - Elsevier
A search for heavy neutral lepton (N) production in K+→ e+ N decays using the data sample
collected by the NA62 experiment at CERN in 2017–2018 is reported. Upper limits of the …

LHC benchmark scenarios for the real Higgs singlet extension of the standard model

T Robens, T Stefaniak - The European Physical Journal C, 2016 - Springer
We present benchmark scenarios for searches for an additional Higgs state in the real Higgs
singlet extension of the Standard Model in Run 2 of the LHC. The scenarios are selected …

Higgs boson potential at colliders: Status and perspectives

B Di Micco, M Gouzevitch, J Mazzitelli, C Vernieri - Reviews in Physics, 2020 - Elsevier
This document summarises the current theoretical and experimental status of the di-Higgs
boson production searches, and of the direct and indirect constraints on the Higgs boson …

Relativistic quantum motion of spin-0 particles under the influence of noninertial effects in the cosmic string spacetime

LCN Santos, CC Barros - The European Physical Journal C, 2018 - Springer
We study solutions for the Klein–Gordon equation with vector and scalar potentials of the
Coulomb types under the influence of noninertial effects in the cosmic string spacetime. We …

Maxi-sizing the trilinear Higgs self-coupling: how large could it be?

L Di Luzio, R Gröber, M Spannowsky - The European Physical Journal C, 2017 - Springer
In order to answer the question on how much the trilinear Higgs self-coupling could deviate
from its Standard Model value in weakly coupled models, we study both theoretical and …

Higgs sector of the minimal left-right symmetric theory

A Maiezza, G Senjanović, JC Vasquez - Physical Review D, 2017 - APS
We perform an in-depth analysis of the Higgs sector in the minimal left-right symmetric
model and compute the scalar mass spectrum and associated mixings, offering simple …

Benchmarks for double Higgs production in the singlet-extended standard model at the LHC

I Lewis, M Sullivan - Physical Review D, 2017 - APS
The simplest extension of the standard model is to add a gauge singlet scalar, S: the singlet-
extended standard model. In the absence of a Z 2 symmetry S→-S and if the new scalar is …

Lepton number violation in Higgs decay at LHC

A Maiezza, M Nemevšek, F Nesti - Physical review letters, 2015 - APS
We show that within the left-right symmetric model, lepton number violating decays of the
Higgs boson can be discovered at the LHC. The process is due to the mixing of the Higgs …
