Abstract
We calculate numerically the cross section for the process\(e^ + e^ - \to ve^ + Q_d \bar Q_u \) using the Weizsäcker-Williams approximation for the virtual photon. This process is a possible background for the detection of an “intermediate” Higgs via its decay into\(Q\bar Q\) pairs. The comparison with the signal allows us to conclude that actually it is not a problem for the Higgs search at high energye + e − colliders.
