Complementary probes of bilinear R-parity violating SUSY models with a winolike LSP via neutrino oscillations and at the LHC
Abstract
In this work, we explore the bilinear R-parity violating Supersymmetry model's parameter space by performing a Markov Chain Monte Carlo scan with neutrino oscillation data, Higgs mass and its coupling strengths, and flavor observables such as B-hadron decay branching ratios. From the allowed parameter space, we analyze the decay patterns of wino-like lighter charginos and lightest neutralinos and demonstrate how the branching ratios to different neutrino and charged lepton flavors depend on the neutrino mass hierarchy. Furthermore, we investigate the impact of current LHC bounds and projected future sensitivities from trilepton resonance searches on the allowed parameter space. We show that considering the branching ratio Br(χ̃1± → Zl±; l= e,μ,τ) ∼23\%, obtained at the best-fit point, the wino-like mass degenerate χ̃1±/χ̃10 are excluded upto 565 GeV from LHC Run-II data. The projected exclusion reach with a similar branching ratio at High-Luminosity LHC (HL-LHC) is around 950 GeV. For a simplified scenario where χ̃1± / χ̃10 decays via a Z boson with branching ratios of 1\%, 50\%, and 100\%, wino masses can be excluded up to approximately 600 GeV, 1185 GeV, and 1350 GeV respectively. Our analysis shows that the HL-LHC can probe a significant portion of the 1σ allowed parameter space by neutrino oscillation measurements and other experimental constraints.

We show that considering the branching ratio Br(χ̃_1^± → Zl^±; l= e,μ,τ) ∼23\%, obtained at the best-fit point, the wino-like mass degenerate χ̃_1^±/χ̃_1^0 are excluded upto 565 GeV from LHC Run-II data.
