Blind spots for neutralino dark matter in the NMSSM [PDF]

open access: yes, 2015
A bstractSpin-independent cross-section for neutralino dark matter scattering off nuclei is investigated in the NMSSM. Several classes of blind spots for direct detection of singlino-Higgsino dark matter are analytically identified, including such that ...

Analysis of the neutralino system in two-body decays of neutralinos [PDF]

open access: yesPhysical Review D, 2004
In the minimal supersymmetric standard model (MSSM), the neutralinos, the spin--1/2 Majorana superpartners of the neutral gauge and Higgs bosons, are expected to be among the light supersymmetric particles that can be produced copiously at future high--energy colliders.

Searches for pair production of charginos and top squarks in final states with two oppositely charged leptons in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
A search for pair production of supersymmetric particles in events with two oppositely charged leptons (electrons or muons) and missing transverse momentum is reported. The data sample corresponds to an integrated luminosity of 35.9 fb−1 of proton-proton

Prospects for Higgs- and Z-resonant Neutralino Dark Matter [PDF]

open access: yes, 2015
In the minimal supersymmetric standard models, neutralino dark matter with mass of $m_{\chi}\sim m_Z/2\sim 45$ GeV and $m_{\chi}\sim m_h/2\sim 62$ GeV can have the thermal relic abundance $\Omega_{\chi_1}h^2\simeq 0.120$ via the $Z$- and Higgs-resonant ...

Dark matter in the CP-violating NMSSM

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
In the Next-to-Minimal Supersymmetric Standard Model there is a strong correlation between the mass terms corresponding to the singlet Higgs and the singlino interaction states, both of which are proportional to the parameter $$\kappa $$ κ .

Search for new phenomena in final states with two opposite-charge, same-flavor leptons, jets, and missing transverse momentum in pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
Search results are presented for physics beyond the standard model in final states with two opposite-charge, same-flavor leptons, jets, and missing transverse momentum. The data sample corresponds to an integrated luminosity of 35.9 fb−1 of proton-proton

Blind Spots for neutralino Dark Matter in the MSSM with an intermediate m_A [PDF]

open access: yes, 2014
We study the spin-independent neutralino Dark Matter scattering off heavy nuclei in the MSSM. We identify analytically the blind spots in direct detection for intermediate values of $m_A$.

Impact of Cosmic‐Ray Physics on Dark Matter Indirect Searches

open access: yesAdvances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
The quest for the elusive dark matter (DM) that permeates the Universe (and in general the search for signatures of physics beyond the Standard Model at astronomical scales) provides a unique opportunity and a tough challenge to the high energy astrophysics community.

Search for exotic decays of a Higgs boson into undetectable particles and one or more photons

open access: yesPhysics Letters B, 2016
A search is presented for exotic decays of a Higgs boson into undetectable particles and one or two isolated photons in pp collisions at a center-of-mass energy of 8 TeV.
