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

Understand

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.
