Abstract
We investigate the flavor changing neutral currents (FCNC) generated by dimension-six four-fermion operators at the Large Hadron-Electron Collider (LHeC) proposed at CERN in an effective approach. This is performed by Monte Carlo analysis at the full detector level, as the background is successfully reduced by using an invariant mass scheme to require the final states to reconstruct the mass (transverse mass) of the top quark ( W boson). Our analysis shows that the future electron proton colliders like the LHeC can probe competitive limits for the top FCNC dimension-six four-fermion operators such as C ( 1 ) e e 31 l q < 0.0647 , C e e 31 l u < 0.109 , C ( 1 ) e e 31 l e q u < 0.217 and C ( 3 ) e e 31 l e q u < 0.0209 in the Warsaw basis.
