摘要
Based on calculating the contributions of the littlest Higgs model with T-parity （called LHT model） to the anomalous top coupling tqγ （q = u or c）, we consider single top production via the t-channel partonic process eq→et in ep collisions. Our numerical results show that the production cross section in the LHT model can be significantly enhanced relative to that in the standard model （SM）.
