Search for sneutrino production in emu final states in 5.3 fb^-1 of ppbar collisions at sqrt(s) =1.96 TeV

TL;DR

This paper reports a search for sneutrino production via RPV interactions in emu final states at the Tevatron, setting bounds on RPV couplings due to no observed resonance signals.

Contribution

It provides the first direct experimental bounds on specific RPV couplings as a function of sneutrino mass using Tevatron data.

Findings

No evidence for emu resonance production.

Set limits on RPV couplings lambda^'_311 and lambda_312.

Constrained sneutrino mass and coupling parameter space.

Abstract

We report the results of a search for R parity violating (RPV) interactions leading to the production of supersymmetric sneutrinos decaying into emu final states using 5.3 fb^-1 of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron Collider. Having observed no evidence for production of emu resonances, we set direct bounds on the RPV couplings lambda^'_311 and lambda_312 as a function of sneutrino mass.
