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

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 can have substantial decay branching ratio to νh in a large part of the parameter space, and thus study the pair production of electroweakinos followed by the decays χ̃₁^±→χ̃₁⁰W^±(∗) and χ̃₁⁰→νh. 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 detector level simulation using a toy calorimeter of both the signal and corresponding backgrounds for the high-luminosity high energy phase of the Large Hadron Collider (LHC). We also advocate some observables based on kinematical features to provide an excellent handle to suppress the backgrounds.
