Contribution

It introduces a novel analysis of top-slepton associated production, emphasizing the polarization asymmetry as a distinctive signature in supersymmetric models.

Findings

Top polarization asymmetry differs significantly from Standard Model predictions.

Distinct kinematic signatures enable separation from Standard Model backgrounds.

Potential for new supersymmetry signals at the LHC.

Abstract

We study the production of a single charged slepton in association with a top quark in a R-parity violating supersymmetric model with lepton number violating interactions at the Large Hadron Collider. We find that the longitudinal polarization asymmetry of the top quark in such a production mode is significantly different from that in the production of a single top or a top pair in the Standard Model for a wide range of slepton masses. Our signal analysis shows that the top-slepton associate production leads to final states with distinct kinematic signatures, which differ from the Standard Model background.
