Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

We consider the dipole portal to sterile neutrinos, also called heavy neutral leptons (HNLs).
The dipole interaction with the photon leads to HNL production in meson decays as well as …

A bstract We consider the minimal see-saw extension of the Standard Model with two right-
handed singlet fermions N 1, 2 with mass at the GeV scale, augmented by an effective …

A bstract We perform a classification of all potential supersymmetric R-parity violating
signatures at the LHC to address the question: are existing bounds on supersymmetric …

A bstract In R-parity-violating (RPV) supersymmetric models, light neutralinos with masses
from the GeV-scale down to even zero are still allowed by all laboratory constraints. They …

A bstract At the Deep Underground Neutrino Experiment (DUNE), a proton beam hits a fixed
target leading to large production rates of mesons. These mesons can decay and potentially …

A bstract 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 neutralino\({\overset …

Neutral particles are notoriously difficult to observe through electromagnetic interactions. As
a result, they naturally elude detection in most collider detectors. In this paper, we point out …

Recently, Belle II announced evidence for the decay $ B^+\to K^+\nu\bar {\nu} $ at
$3.6\sigma $ significance, and measured the corresponding decay branching ratio to be …

Recently, Soleti et al.[J. High Energy Phys. 03 (2024) 148 JHEPFG 1029-8479
10.1007/JHEP03 (2024) 148] proposed a new experiment called SHiNESS at the upcoming …
