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 .

Neutralino-neutralino annihilation to photon and gluon pairs in MSSM models [PDF]

open access: yesPhysical Review D, 2004
The complete 1-loop computation of the processes $(\tchi^0_i \tchi^0_j \leftrightarrow , ~ gg)$, for any pair of the four MSSM neutralinos, has been performed for an arbitrary c.m energy. As a first application suitable for Dark Matter (DM) searches, the neutralino-neutralino annihilation is studied at relative velocities $v/c\simeq 10^{-3 ...

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

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.

The Discreet Charm of Higgsino Dark Matter: A Pocket Review

open access: yesAdvances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
We give a brief review of the current constraints and prospects for detection of higgsino dark matter in low‐scale supersymmetry. In the first part we argue, after performing a survey of all potential dark matter particles in the MSSM, that the (nearly) pure higgsino is the only candidate emerging virtually unscathed from the wealth of observational ...
