Altres ajuts: We thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently. We acknowledge the support of ARTEMIS and ERC, European Union and MICINN, PIC, Spain. ; The top quark mass has been measured using the template method in the channel based on data recorded in 2011 with the ATLAS detector at the LHC. The data were taken at a proton-proton centre-of-mass energy of and correspond to an integrated luminosity of 1.04 fb −1. The analyses in the e +jets and μ +jets decay channels yield consistent results. The top quark mass is measured to be m =174.5±0.6±2.3 GeV.

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.

The results were obtained from data corresponding to an integrated luminosity of 2.1 fb −1 collected in proton-proton collisions at with the ATLAS detector at the CERN Large Hadron Collider. No excess above the Standard Model background expectation is observed. Excluded mass regions for Majorana and Dirac neutrinos are presented using two approaches for interactions that violate lepton and lepton-flavor numbers. One approach uses an effective operator framework, the other approach is guided by the Left-Right Symmetric Model. The results described in this letter represent the most stringent limits to date on the masses of heavy neutrinos and W bosons obtained in direct searches.
