Collider constraints on electroweakinos in the presence of a light gravitino

V Ananyev, C Balázs, A Beniwal, LL Braseth… - The European Physical …, 2023 - Springer
Using the GAMBIT global fitting framework, we constrain the MSSM with an eV-scale
gravitino as the lightest supersymmetric particle, and the six electroweakinos (neutralinos …

Testing neutrino dipole portal by long-lived particle detectors at the LHC

W Liu, Y Zhang - The European Physical Journal C, 2023 - Springer
We discuss the potential of using detectors aimed for searching long-lived particles (LLP) at
the high-luminosity LHC run, to probe the neutrino dipole models. This is achieved by taking …

Lighting up the LHC with Dark Matter

S Baum, M Carena, T Ou, D Rocha, NR Shah… - Journal of High Energy …, 2023 - Springer
A bstract We show that simultaneously explaining dark matter and the observed value of the
muon's magnetic dipole moment may lead to yet unexplored photon signals at the LHC. We …

Twin Higgs portal dark matter

D Curtin, S Gryba - Journal of High Energy Physics, 2021 - Springer

problem are either excluded or severely constrained by LHC and direct detection null …

Resonant heavy Higgs searches at the HL-LHC

A Adhikary, S Banerjee, RK Barman… - Journal of High Energy …, 2019 - Springer

Reexamining right-handed neutrino EFTs up to dimension six

M Mitra, S Mandal, R Padhan, A Sarkar… - Physical Review D, 2022 - APS
