Search for High-Mass Resonances Decaying into Leptons of Different Flavor ($e\mu$, $e\tau$, $\mu\tau$)

TL;DR

This paper reports a search for high-mass particles decaying into different-flavor lepton pairs ($e\mu$, $e au$, $\mu au$) using Tevatron data, aiming to find evidence of physics beyond the Standard Model.

Contribution

It introduces a search for flavor-violating high-mass resonances in leptonic decay channels using Tevatron data, which has not been extensively explored before.

Findings

No significant excess observed in the data.

Sets limits on the production cross-section of such resonances.

Provides constraints on models predicting flavor-violating particles.

Abstract

We present a search for high-mass resonances decaying into two leptons of different flavor: $e\mu$, $e\tau$ and $\mu\tau$. These resonances are predicted by several models for Physics Beyond the Standard Model, such as R-parity-violating MSSM. The search is based on 1 ${\rm fb^{-1}}$ of Tevatron Run II data collected with the CDF detector at $\sqrt{s}$ = 1.96 TeV in proton anti-proton collisions.
