Event-shape selection cuts for supersymmetry searches at the LHC with 7 TeV energy

TL;DR

This paper proposes a new event-shape based selection method for supersymmetry searches at the 7 TeV LHC, aiming to effectively reduce backgrounds and extend the mass reach to about 1.1 TeV with 1/fb luminosity.

Contribution

It introduces a novel set of event-shape selection cuts that improve background control in supersymmetry searches at the LHC.

Findings

Backgrounds can be minimized to low levels using the new cuts.

Mass reach for supersymmetry can be extended to approximately 1.1 TeV.

The method shows promise for early LHC data analysis.

Abstract

We investigate the prospects of supersymmetry searches at the LHC with 7 TeV energy. A new set of selection cuts is proposed based on event shapes to control backgrounds. Our preliminary studies show that it is possible to minimize backgrounds to a significantly low level and conservative estimate suggests that the mass reach can be extended to $\sim$ 1.1 TeV for luminosity 1/fb with a reasonable signal-to-background ratio.
