Can Flavor Physics Hint at Distinctive Signals for R-parity Violation at the LHC?

TL;DR

This paper explores how flavor physics anomalies might indicate R-parity violation in supersymmetry, predicting distinctive multilepton signals at the LHC that could be detectable early on.

Contribution

It provides a detailed analysis linking low-energy flavor physics signals with potential R-parity-violating supersymmetric signatures at the LHC, including background considerations.

Findings

R-parity violation can produce observable multilepton signals at the LHC.

Such signals may be detectable even in early LHC runs.

Correlations with low-energy flavor physics support the scenario.

Abstract

Observation of some low-energy processes in the flavor physics regime may require the existence of supersymmetry with two relatively large R-parity-violating couplings of the LQD-type, together with reasonably light superparticles. At the LHC, such interactions would be expected to give rise to clear signals with convenient leptonic triggers, including some multileptons of the same sign. We undertake a detailed investigation of these signals taking care to correlate with low-energy requirements and taking proper account of the Standard Model backgrounds as well as the R-parity-conserving sector of the supersymmetric model. We find clear indications that R-parity violation as envisaged in this scenario can be detected at the LHC - even, perhaps, in the early runs.
