the Large Hadron Collider (LHC) that can detect light long-lived particles produced in the …

Light scalar production from Higgs bosons and FASER 2

I Boiarska, K Bondarenko, A Boyarsky… - Journal of High Energy …, 2020 - Springer
A bstract The most general renormalizable interaction between the Higgs sector and a new
gauge-singlet scalar S is governed by two interaction terms: cubic and quartic. The quartic …

Sensitivity of the FACET experiment to heavy neutral leptons and dark scalars

M Ovchynnikov, V Kryshtal, K Bondarenko - Journal of High Energy …, 2023 - Springer
A bstract We analyze the potential of the recently proposed experiment FACET (Forward-
Aperture CMS ExTension) to search for new physics. As an example, we consider the …

Dark Higgs bosons at FASER

JL Feng, I Galon, F Kling, S Trojanowski - arXiv preprint arXiv:1710.09387, 2017 - arxiv.org
FASER, ForwArd Search ExpeRiment at the LHC, has been proposed as a small, very far
forward detector to discover new, light, weakly-coupled particles. Previous work showed that …

Direct production of light scalars in the type-I two-Higgs-doublet model at the lifetime frontier of the LHC

W Liu, L Wang, Y Zhang - Physical Review D, 2024 - APS
A light pseudoscalar A in the sufficient large tan β region of type-I two-Higgs-doublet model
can be naturally a long-lived particle. We focus on H±A, HA, and AA pair productions via the …

Dark Higgs bosons at the forward search experiment

JL Feng, I Galon, F Kling, S Trojanowski - Physical Review D, 2018 - APS
FASER, ForwArd Search ExpeRiment at the LHC, has been proposed as a small, very far
forward detector to discover new, light, weakly-coupled particles. Previous work showed that …

Unravelling the richness of dark sector by FASERν

P Bakhti, Y Farzan, S Pascoli - Journal of High Energy Physics, 2020 - Springer
A bstract FASERν is a newly proposed experiment which will take data in run III of the LHC
during 2021–2023. It will be located in front of the FASER detector, 480 m away from the …

Light signals from a lighter Higgs

PJ Fox, N Weiner - Journal of High Energy Physics, 2018 - Springer
A bstract With the Higgs search program already quite mature, there is the exciting
possibility of discovering a new particle with rates near that of the SM Higgs. We consider …

Phenomenological signatures of additional scalar bosons at the LHC

S Von Buddenbrock, N Chakrabarty, AS Cornell… - The European Physical …, 2016 - Springer
We investigate the search prospects for new scalars beyond the standard model at the large
hadron collider (LHC). In these studies two real scalars S and χ χ have been introduced in a …

Light octet scalars, a heavy Higgs and minimal flavour violation

CP Burgess, M Trott, S Zuberi - Journal of High Energy Physics, 2009 - iopscience.iop.org
It is widely believed that existing electroweak data requires a Standard Model Higgs to be
light while electroweak and flavour physics constraints require other scalars charged under …
