Search for new phenomena in final states with b-jets and missing transverse momentum in s $$ \sqrt{\mathrm{s}} $$ = 13 TeV pp collisions with the ATLAS detector

open access: yesJournal of High Energy Physics, 2021
The results of a search for new phenomena in final states with b-jets and missing transverse momentum using 139 fb −1 of proton-proton data collected at a centre-of-mass energy s $$ \sqrt{s} $$ = 13 TeV by the ATLAS detector at the LHC are reported.

SUSY-QCD corrections to squark annihilation into gluons and light quarks

open access: yesSciPost Physics Proceedings, 2023
We calculate the full one-loop SUSY-QCD corrections to stop annihilation into gluons and light quarks including the Sommerfeld enhancement effect and discuss their impact on the neutralino relic density in the MSSM.

Corrections to Yukawa couplings from higher dimensional operators in a natural SUSY SO(10) and HL-LHC implications

open access: yesJournal of High Energy Physics, 2021
We consider a class of unified models based on the gauge group SO(10) which with appropriate choice of Higgs representations generate in a natural way a pair of light Higgs doublets needed to accomplish electroweak symmetry breaking.

Naturalness and dark matter in a realistic intersecting D6-brane model

open access: yesJournal of High Energy Physics, 2018
We revisit a three-family Pati-Salam model with a realistic phenomenology from intersecting D6-branes in Type IIA string theory compactified on a T 6 /(ℤ2 × ℤ2) orientifold, and study its naturalness in view of the current LHC and dark matter searches ...

Search for direct pair production of supersymmetric partners to the $${\uptau }_{}^{}$$ τ lepton in proton–proton collisions at $$\sqrt{s}=13\,\text {TeV} $$ s=13TeV

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
A search is presented for $${\uptau }_{}^{}$$ τ slepton pairs produced in proton–proton collisions at a center-of-mass energy of 13$$\,\text {TeV}$$ TeV . The search is carried out in events containing two $${\uptau }_{}^{}$$ τ leptons in the final state,

Superheavy dark matter from string theory

open access: yesJournal of High Energy Physics, 2021
Explicit string models which can realize inflation and low-energy supersymmetry are notoriously difficult to achieve. Given that sequestering requires very specific configurations, supersymmetric particles are in general expected to be very heavy ...

Revisiting a Realistic Intersecting D6-Brane with Modified Soft SUSY Terms

open access: yesUniverse
Because there are a few typos in the supersymmetry-breaking sfermion masses and trilinear soft term, regarding the current Large Hadron Collider (LHC) and dark matter searches, we revisit a three-family Pati–Salam model based on intersecting D6-branes in

Dark matter in NMSSM with small λ and κ

open access: yesResults in Physics, 2023
The NMSSM provides an excellent dark matter candidate, usually the lightest neutralino (χ̃10) being the lightest supersymmetric particle (LSP), in the universe. It is a mixture of the bino, the neutral wino, the neutral higgsinos, and the singlino.

Neutralino dark matter in scenarios with early matter domination

open access: yesJournal of High Energy Physics, 2018
We investigate the production of neutralino dark matter in a cosmological scenario featuring an early matter dominated era ending at a relatively low reheating temperature.

The R-parity violating decays of charginos and neutralinos in the B-L MSSM

open access: yesJournal of High Energy Physics, 2019
The B − L MSSM is the MSSM with three right-handed neutrino chiral multiplets and gauged B − L symmetry. The B − L symmetry is broken by the third family right-handed sneutrino acquiring a VEV, thus spontaneously breaking R-parity. Within a natural range
