Search for lepton flavour violating in top quark production and decay at the LHC

• shirin Chenarani (Institute for Research in Fundamental Sciences (IPM))

In this talk, I will present the results of our recent analysis for searching for lepton flavor violation signature in top quark sector using data collected at 13 TeV at the LHC.The search is based on the datasets collected by the CMS detector in 2016, 2017 and 2018. The results are interpreted in the framework of an effective field theory.
