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.

Analysis of the neutralino system in three–body leptonic decays of neutralinos [PDF]

open access: yesThe European Physical Journal C, 2006
Neutralinos $\tilde ^0$ in supersymmetric theories, the spin--1/2 Majorana--type superpartners of the U(1) and SU(2) neutral electroweak gauge bosons and SU(2) neutral Higgs bosons, are expected to be among light supersymmetric particles so that they can be produced copiouslyvia direct pair production and/or from cascade decays of other sparticles ...

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.

Phenomenology of Dirac Neutralino Dark Matter [PDF]

open access: yes, 2013
In supersymmetric models with an unbroken R-symmetry (rather than only R-parity), the neutralinos are Dirac fermions rather than Majorana. In this article, we discuss the phenomenology of neutralino dark matter in such models, including the calculation ...

Coupled Boltzmann computation of mixed axion neutralino dark matter in the SUSY DFSZ axion model [PDF]

open access: yes, 2013
The supersymmetrized DFSZ axion model is highly motivated not only because it offers solutions to both the gauge hierarchy and strong CP problems, but also because it provides a solution to the SUSY μ-problem which naturally allows for a Little Hierarchy.

QCD corrections to neutralino–nucleon scattering [PDF]

open access: yesPhysics Letters B, 2000
We calculate the dominant loop corrections from both standard and supersymmetric QCD to the effective coupling of neutralinos to nucleons. The potentially largest corrections come from gluino-squark loop contributions to the Higgs boson couplings to quarks; these corrections also affect the leading spin-independent squark exchange contribution ...

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 ...
