This paper presents a search for the t-channel ex- change of an R-parity violating scalar top quark (t ̃) in the e±μ∓ 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 → eμX, 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 ex- change of an R-parity violating scalar top quark (t ̃) in the e±μ∓ 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 → eμX, 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.File | Dimensione | Formato | |
