LHC searches for physics beyond the Standard Model with top quarks
Tobias Golling (on behalf of the ATLAS, CMS Collaborations)
TL;DR
This paper reports on searches for new physics beyond the Standard Model involving top quarks using LHC data, setting limits on new particles due to no observed deviations.
Contribution
It presents the first combined analysis of top-quark related signatures at 7 TeV with limits on new particles in various benchmark models.
Findings
Data are consistent with the Standard Model
Limits are set on production cross sections and particle masses
No evidence of new physics observed
Abstract
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.
