Search for lepton flavour violation in the emu continuum with the ATLAS detector in $sqrts=7$ TeV $pp$ collisions at the LHC

Abstract

This paper presents a search for the t-channel exchange of an R-parity violating scalar top quark (={t}) in the emu continuum using 2.1/fb of data collected by the ATLAS detector in sqrt(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 (m_{={t}}). The upper limits on the production cross section for pp->emuX, through the t-channel exchange of a scalar top quark, ranges from 170 fb for m_{={t}}=95 GeV to 30 fb for m_{={t}}=1000 GeV.
