Searching for long-lived light neutralinos from $B$-meson decays with baryonic R-parity violation at Belle II

Emilie Bertholet, Claudio O. Dib, Sara P. Gandelman +6

In a supersymmetry scenario with R-parity violation (RPV), neutralinos with GeV-scale mass, which are necessarily bino-like, are allowed by all constraints and can be produced in a…
