Di-Higgs signatures from R-parity violating supersymmetry as the origin of neutrino mass

Understand

Motivated by the naturalness and neutrino mass generation, we study a bilinear R-parity violating supersymmetric scenario with a light Higgsino-like lightest supersymmetric particle (LSP).

• We observe that the LSP dominantly decays to $\nu h$ in a large part of the parameter space, and thus study the pair production of electroweakinos followed by the decays $\tilde\chi^\pm_1\to \tilde\chi^0_1 W^{\pm*}$ and $\tilde\chi^0_1\to \nu h$.
• This leads to an interesting signature of Higgs boson pair production associated with significantly large missing transverse energy which is grossly distinct from the di-Higgs production in the Standard Model.
• We investigate the perspective of probing such signatures by performing a realistic detector level simulation of both the signal and corresponding backgrounds for the high-luminosity high energy phase of the Large Hadron Collider (LHC).
