We study the relevant background processes including one electron and three jets in the final state. The distributions of the invariant mass of two jets and an additional jet tagged as b-jet are used to account for signal and background events after the analysis cuts. We find upper bounds on anomalous FCNC couplings.. of the order of 10(-2) at LHeC for a luminosity projection of 500fb(-1) together with the fast simulation of detector effects. As a matter of interest, we analyze the sensitivity to the couplings (lambda(mu),lambda(c)) and find an enhanced sensitivity to lambda(c) at the LHeC when compared to the results from the HERA.qeninfo:eu-repo/semantics/openAccessLarge Hadron Electron ColliderFCNC tqy CouplingsFlavour Changing Neutral Current (FCNC)Article10.1155/2017/157205320172-s2.0-85030660645Q2WOS:000411599000001Q3
