           Rashidul presented about the study on
    anomalous top FCNC coupling search.
    The background is assumed to be the
    SM single top production.  They noticed
    that, for large values of FCNC couplings,
    the cross sections calculated by MadGraph
    tend to show turn-over and decreasing behaviour.

    To be noted, the couplings are taken at production level only which affect the decay width of top-quark in case top decay to Wb and further leptonic and hadronic decay of W is taken into account.
    It might be related to narrow width approximation  and the cause may be figure-out by thoroughly  analytical calculations. Further then we need to  check on MG5 limitations as suggested/discussed. 


    Uta and Masahiro commented that the current limit
    is much below 1 and one does not need to worry
    about the behavior for very large values.
