R-parity violation: Hide & Seek [PDF]

, 2006
We point out that, if R-parity is broken spontaneously, the neutralino can decay to the final state majoron plus neutrino, which from the experimental point of view is indistinguishable from the standard missing momentum signal of supersymmetry.

Scrutinizing $R$-parity violating interactions in light of $R_{K^{(\ast)}}$ data [PDF]

, 2017
The LHCb has measured the ratios of $B\to K^\ast\mu^+\mu^-$ to $B\to K^\ast e^+ e^-$ branching fractions in two dilepton invariant mass squared bins, which deviate from the Standard Model predictions by approximately $2.5\sigma$.

The R-parity violating decays of charginos and neutralinos in the B-L MSSM [PDF]

Journal of High Energy Physics, 2018
A bstractThe B − L MSSM is the MSSM with three right-handed neutrino chiral multiplets and gauged B − L symmetry. The B − L symmetry is broken by the third family right-handed sneutrino acquiring a VEV, thus spontaneously breaking R-parity.

Probing neutrino mass with multilepton production at the Tevatron in the simplest R-parity violation model [PDF]

, 2003
We analyze the production of multileptons in the simplest supergravity model with bilinear violation of R parity at the Fermilab Tevatron. Despite the small R-parity violating couplings needed to generate the neutrino masses indicated by current ...

A $$\nu $$ ν approach to analyzing neutrino data in the $${\textbf{R}}$$ R -parity-violating MSSM

European Physical Journal C: Particles and Fields, 2023
The R-parity-violating Minimal Supersymmetric Standard Model (RPV-MSSM) can naturally accommodate massive neutrinos as required by the oscillation data. However, studying the phenomenology is complicated due to the large number of undetermined parameters

, 2017
A search is presented for the direct pair production of the stop, the supersymmetric partner of the top quark, that decays through an R-parity-violating coupling to a final state with two leptons and two jets, at least one of which is identified as a b ...

R-Parity Violation at HERA ? [PDF]

, 1997
We examine the possibility that the high-Q^2 events seen at HERA are due to the production and decay of squarks of R-parity violating supersymmetry.
