Signatures of Resonant Super-Partner Production with Charged-Current Decays

TL;DR

This paper explores collider signatures of supersymmetric particles decaying via charged-current processes, proposing a scenario consistent with observed anomalies and suggesting additional observable signatures for confirmation.

Contribution

It introduces a novel supersymmetric decay topology involving resonant super-partner production with charged-current decays, aligning with experimental observations and proposing new detection strategies.

Findings

The proposed scenario can explain the Wjj excess observed by CDF.

Charge asymmetry at the LHC can serve as a confirmation signal.

Additional signatures include 4-jet and WW + 4-jet events with resonant substructures.

Abstract

Hadron collider signatures of new physics are investigated in which a primary resonance is produced that decays to a secondary resonance by emitting a W-boson, with the secondary resonance decaying to two jets. This topology can arise in supersymmetric theories with R-parity violation where the lightest supersymmetric particles are either a pair of squarks, or a slepton - sneutrino pair. The resulting signal can have a cross section consistent with the Wjj observation reported by the CDF collaboration, while remaining consistent with earlier constraints. Other observables that can be used to confirm this scenario include a significant charge asymmetry in the same channel at the LHC. With strongly interacting resonances such as squarks, pair production topologies additionally give rise to 4 jet and WW + 4 jet signatures, each with two equal-mass dijet resonances within the 4 jets.
