Search for Anomalous Top Chromomagnetic Dipole Moments from angular distributions in $t\bar{t}$ Dileptonic events at $\sqrt{s}=7$ TeV with the CMS detector.

A search for new physics in the form of a top quark chromo-magnetic anomalous coupling is performed using a previous measurement of the differential $\mathrm{t\bar{t}}$ cross section as a function of the difference in azimuthal angle between the two charged leptons, $|\Delta \phi_{ll}|$, in the dile...

description A search for new physics in the form of a top quark chromo-magnetic anomalous coupling is performed using a previous measurement of the differential $\mathrm{t\bar{t}}$ cross section as a function of the difference in azimuthal angle between the two charged leptons, $|\Delta \phi_{ll}|$, in the dilepton decay mode. The measured value of $Re(\hat{\mu}_t)$ is $0.037 \pm 0.041$ and no sign of new physics is observed. Limits on the real part of the chromomagnetic dipole moment $Re(\hat{\mu}_t)$ are determined at 95\% Confidence Level as -0.043$< Re(\hat{\mu}_t) < $0.117.
