Searches for Prompt R‐Parity‐Violating Supersymmetry at the LHC

open access: yesAdvances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015
Searches for supersymmetry (SUSY) at the LHC frequently assume the conservation of R‐parity in their design, optimization, and interpretation. In the case that R‐parity is not conserved, constraints on SUSY particle masses tend to be weakened with respect to R‐parity‐conserving models.

Black Component of Dark Matter

open access: yesAdvances in High Energy Physics, Volume 2014, Issue 1, 2014., 2014
A mechanism of primordial black hole formation with specific mass spectrum is discussed. It is shown that these black holes could contribute to the energy density of dark matter. Our approach is elaborated in the framework of universal extra dimensions.

Dark radiation constraints on mixed Axion/Neutralino dark matter [PDF]

open access: yes, 2013
Recent analyses of CMB data combined with the measurement of BAO and H0 show that dark radiation — parametrized by the apparent number of additional neutrinos ΔNeff contributing to the cosmic expansion — is bounded from above by about ΔNeff1.6 at 95% CL.

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.
