I will present ongoing work on light neutralinos with baryon-number-violating R-parity-violating (RPV) couplings at Belle II. Neutralinos can be produced in B-meson decays and subsequently decay into baryon-meson pairs, leading to displaced-vertex (DV) signatures. We employ partial reconstruction techniques to enhance signal efficiency and suppress backgrounds. Using Monte Carlo simulations,...
Recent high-precision cosmological data tighten the bound to neutrino masses and start rising a tension to the results of lab-experiment measurements, which may hint new physics in the role of neutrinos during the structure formation in the universe. A scenario with massless sterile neutrinos was proposed to alleviate the cosmological bound and recover the concordance in the measurements of...
This talk provides an update on the current status of future collider projects, like the Compact Linear Collider (CLIC), the Future Circular Collider (FCC). It briefly outlines their progress and ongoing developments, while also addressing the European Strategy for Particle Physics recommendations.
I this context, Lepton flavour violating Higgs decays could appear in models beyond the...
