Abstract
Several global symmetries of the Standard Model -- Lorentz invariance, CPT and CP symmetries -- are tested with top quarks and Higgs bosons using LHC data collected with the CMS detector. Top-antitop ($t\bar{t}$) production is used to probe CPT symmetry and Lorentz invariance. The top-boson coupling is employed to test the CP symmetry, in the top quark coupling to the gluon with the $t\bar{t}$ process, in the top quark coupling to the Z boson with $t\bar{t}\gamma/Z$ processes, and in the top quark coupling to the Higgs boson with the $t\bar{t}H$ process.
