How heavy can neutralino dark matter be?

open access: yesJournal of High Energy Physics, 2019
What is the upper limit of the mass of the neutralino dark matter whose thermal relic is consistent with the observation? If the neutralino dark matter and colored sparticles are extremely degenerated in mass, with a mass difference less than the QCD ...

Employing nucleon decay as a fingerprint of SUSY GUT models using SusyTCProton

open access: yesJournal of High Energy Physics, 2021
While the observation of nucleon decay would be a smoking gun of Grand Unified Theories (GUTs) in general, the ratios between the decay rates of the various channels carry rich information about the specific GUT model realization.

Beyond the Standard Model [PDF]

open access: yes, 2015
We introduce aspects of physics beyond the Standard Model focusing on supersymmetry, extra dimensions, and a composite Higgs as solutions to the Hierarchy problem.

Minimal non-abelian supersymmetric Twin Higgs

open access: yesJournal of High Energy Physics, 2017
We propose a minimal supersymmetric Twin Higgs model that can accommodate tuning of the electroweak scale for heavy stops better than 10% with high mediation scales of supersymmetry breaking.

Indirect probe of electroweakly interacting particles at the high-luminosity Large Hadron Collider

open access: yesJournal of High Energy Physics, 2018
Many extensions of the standard model (SM) involve new massive particles charged under the electroweak gauge symmetry. The electroweakly interacting new particles affect various SM processes through radiative corrections.

Impact of an extra gauge interaction on naturalness of supersymmetry

open access: yesJournal of High Energy Physics, 2018
It is pointed out that in supersymmetric models with a new gauge symmetry under which the Higgs is charged, the fine-tuning of the electroweak symmetry breaking is relaxed due to suppression of the top Yukawa coupling at higher scales by a new large ...

Comparatively light extra Higgs states as signature of SUSY SO(10) GUTs with 3rd family Yukawa unification

open access: yesJournal of High Energy Physics, 2020
We study 3rd family Yukawa unification in the context of supersymmetric (SUSY) SO (10) GUTs and SO(10)-motivated boundary conditions for the SUSY-breaking soft terms.

Probing compressed dark sectors at 100 TeV in the dileptonic mono-Z channel

open access: yesJournal of High Energy Physics, 2018
We examine the sensitivity at a future 100 TeV proton-proton collider to compressed dark sectors whose decay products are invisible due to below-threshold energies and/or small couplings to the Standard Model.

Interference effects in dilepton resonance searches for Z′ bosons and dark matter mediators

open access: yesJournal of High Energy Physics, 2020
New Z′ gauge bosons arise in many extensions of the Standard Model and predict resonances in the dilepton invariant mass spectrum. Searches for such resonances therefore provide important constraints on many models of new physics, but the resulting ...
