| Özet |
| A search for violation of Lorentz invariance in the production of top quark pairs (t t‾) is presented. The measured normalized differential t t‾ production cross section, as a function of the sidereal time, is examined for potential modulations induced by Lorentz-invariance breaking operators in an effective field theory extension of the standard model (SM). The cross section is measured from collision events collected by the CMS detector at a center-of-mass-energy of 13 TeV, corresponding to an integrated luminosity of 77.8 fb− 1, and containing one electron and one muon. The results are found to be compatible with zero, in agreement with the SM, and are used to place upper limits at 68% confidence level on the magnitude of the Lorentz-violating couplings ranging from 1–8× 10− 3. This is the first precision test of the isotropy in special relativity with top quarks at the LHC, restricting further the bounds on such couplings … |
