Flavonstrahlung in the B 3 − L 2 Z′ model at current and future colliders
Journal of High Energy Physics, 2023 The B 3 − L 2 Z′ model may explain some gross features of the fermion mass spectrum as well as b → sℓℓ anomalies. A TeV-scale physical scalar field associated with gauged U 1 B 3 − L 2 $$ U{(1)}_{B_3-{L}_2} $$ spontaneous symmetry breaking, the flavon ...

Journal of High Energy Physics, 2023 The future muon collider can play as an ideal machine to search for new physics at high energies. In this work, we study the search potential of the heavy Higgs triplet in the Type II Seesaw mechanism at muon colliders with high collision energy and high

Investigating the Sterile Neutrino Parameters with QLC in 3 + 1 Scenario
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 In the scenario with four generation quarks and leptons and using a 3 + 1 neutrino model having one sterile and the three standard active neutrinos with a 4 × 4 unitary transformation matrix, UPMNS4, we perform a model‐based analysis using the latest global data and determine bounds on the sterile neutrino parameters i.e., the neutrino mixing angles ...

Asymmetric leptoquark pair production at LHC
Journal of High Energy Physics, 2023 We investigate asymmetric leptoquark pair production mechanism at the Large Hadron Collider to advocate its potential relevance to establish reliable constraints on the leptoquark parameter space and its ability to aid in correct identification of these ...

Modified Higgs Sectors and NLO Associated Production
, 2013 Many beyond the Standard Model (BSM) scenarios involve Higgs couplings to additional electroweak fields. It is well established that these new fields may modify Higgs gamma-gamma and gamma-Z decays at one-loop.

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 I review the construction of simplified models for dark matter searches. After discussing the philosophy and some simple examples, I turn the attention to the aspect of the theoretical consistency and to the implications of the necessary extensions of these models.

dE/dx from boosted long-lived particles
Journal of High Energy Physics, 2022 At colliders massive long-lived charged particles could be revealed through their anomalously large ionisation energy loss dE/dx. In this paper we explore a class of scenarios in which the LLPs are particularly boosted, owing to production from the decay

Vector boson fusion at multi-TeV muon colliders
, 2020 High-energy lepton colliders with a centre-of-mass energy in the multi-TeV range are currently considered among the most challenging and far-reaching future accelerator projects. Studies performed so far have mostly focused on the reach for new phenomena

The Discreet Charm of Higgsino Dark Matter: A Pocket Review
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We give a brief review of the current constraints and prospects for detection of higgsino dark matter in low‐scale supersymmetry. In the first part we argue, after performing a survey of all potential dark matter particles in the MSSM, that the (nearly) pure higgsino is the only candidate emerging virtually unscathed from the wealth of observational ...

The role of vector boson fusion in the production of heavy vector triplets at the LHC and HL-LHC
Journal of High Energy Physics, 2022 We clarify the role of vector boson fusion (VBF) in the production of heavy vector triplets at the LHC and the HL-LHC. We point out that the presence of VBF production leads to an unavoidable rate of Drell-Yan (DY) production and highlight the subtle ...
