Recasting bounds on long-lived heavy neutral leptons in terms of a light supersymmetric R-parity violating neutralino
In R-parity-violating (RPV) supersymmetric models, light neutralinos with masses from the GeV-scale down to even zero are still allowed by all...

Decay of a Polarized Chargino (Neutralino) Into a Polarized Neutralino and a Gauge Boson
Within the framework of the Minimal Supersymmetric Standard Model, the decay of a polarized chargino (neutralino) into a polarized neutralino and a...

Probing R-parity violation in B-meson decays to a baryon and a light neutralino
We propose a search for B meson decays to a baryon plus missing energy at the Belle II experiment to probe supersymmetry with a GeV-scale lightest...

Supersymmetric explanation of the muon g – 2 anomaly with and without stable neutralino
In this paper we explore the possibility of explaining the muon g − 2 anomaly in various types of supersymmetric extensions of the Standard Model. In...

Electroweak resummation of neutralino dark-matter annihilation into high-energy photons
We consider the resummation of large electroweak Sudakov logarithms for the annihilation of neutralino DM with (TeV) mass to high-energy photons in...

Anapole moment of Majorana fermions and implications for direct detection of neutralino dark matter
For Majorana fermions the anapole moment is the only allowed electromagnetic multipole moment. In this work we calculate the anapole moment induced...

Synchrotron emission from neutralino dark matter annihilation in dwarf spheroidal galaxies
The existence of non-baryonic cold dark matter has been established by several astrophysical evidences. In the regions of high dark matter density,...

A decaying neutralino as dark matter and its gamma ray spectrum
It is shown that a decaying neutralino in a supergravity unified framework is a viable candidate for dark matter. Such a situation arises in the...

NMSSM neutralino dark matter for CDF II W-boson mass and muon g − 2 and the promising prospect of direct detection
Two experiments from the Fermilab, E989 and CDF II, have reported two anomalies for muon g − 2 and W -boson mass that may indicate the new physics at...

Searching for a single photon from lightest neutralino decays in R-parity-violating supersymmetry at FASER
In this work, we propose a search for a single photon at FASER and FASER2, produced from decays of bino-like, sub-GeV lightest neutralinos in the...

The hMSSM with a light gaugino/higgsino sector: implications for collider and astroparticle physics
The hMSSM is a special parameterization of the minimal supersymmetric extension of the Standard Model (MSSM) in which the mass of the lightest Higgs...

Neutrinoless double beta decay via light neutralinos in R-parity violating supersymmetry
We perform a study of neutrinoless double beta (0 νββ ) decay mediated by the lightest neutralino of arbitrary mass in the minimal supersymmetric...

Collider constraints on electroweakinos in the presence of a light gravitino
Using the
