| and to measure its couplings to the SM vector bosons. The top mass will be obtained at 350 GeV, by scanning the threshold of the top pair production. The top couplings to the photon and the Z0 will be measured at about 500 GeV. | ||||||||

| For both measurements, a precise mastering of the ElectroWeak loop corrections is essential since it appears that they induce sizeable corrections to the leading mechanisms (typically 5-10%) far larger than the precision achievable at the ILC. | ||||||||

| < < | The goals of the TYL project “top-ILC” are twofold: strengthen further the 500 GeV analysis that has been developed in the past years using semi-leptonic events (0), and design means to control theoretically and experimentally the ElectroWeak loop corrections. | |||||||

| In that respect, following the first top-ILC workshop held in KeK (2013) one of the approach that is pursued is to assess the potential of the double leptonic events, where both W’s decay leptonically. | ||||||||
| Changed: | ||||||||
| < < | Using Monte Carlo events provided by GRACE(1), it has been shown that experimentally one can cope with the two missing neutrinos and that a Matrix Element(2) analysis of the events using Leading Order expressions(3) should provide top-coupling measurements with an accuracy similar to the one attained using the semi-leptonic events, but with different systematical effects. | |||||||
