This paper presents a search for the t-channel exchange of an R-parity violating scalar top quark ( t?? ) in the e ± ?? ??? continuum using 2.1 fb???1 of data collected by the ATLAS detector in s=7 TeV pp collisions at the Large Hadron Collider. Data are found to be consistent with the expectation from the Standard Model backgrounds. Limits on R-parity-violating couplings at 95 % C.L. are calculated as a function of the scalar top mass ( mt?? ). The upper limits on the production cross section for pp???e??X, through the t-channel exchange of a scalar top quark, ranges from 170 fb for mt??=95 GeV to 30 fb for mt??=1000 GeV .

Abstract
This paper presents a search for the t-channel exchange of an R-parity violating scalar top quark ( t?? ) in the e ± ?? ??? continuum using 2.1 fb???1 of data collected by the ATLAS detector in s=7 TeV pp collisions at the Large Hadron Collider. Data are found to be consistent with the expectation from the Standard Model backgrounds. Limits on R-parity-violating couplings at 95 % C.L. are calculated as a function of the scalar top mass ( mt?? ). The upper limits on the production cross section for pp???e??X, through the t-channel exchange of a scalar top quark, ranges from 170 fb for mt??=95 GeV to 30 fb for mt??=1000 GeV .I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
