Query: LHC searches for physics beyond the Standard Model with top quarks   Searches are presented for physics beyond the Standard Model involving
top-quark and related signatures. The results are based on proton-proton
collision data corresponding to integrated luminosities between 1 fb-1 and 5
fb-1 collected at a center-of-mass energy of 7 TeV with the ATLAS and CMS
detectors at the Large Hadron Collider in 2011. The data are found to be
consistent with the Standard Model. The non-observation of a signal is
converted to limits at the 95% confidence level on the production cross section
times branching ratio and on the masses of the hypothesized new particles for
appropriate benchmark models.
