%0 Journal Article %T BSM constraints from EW measurements %A Degrande %A Celine %J High Energy Physics - Phenomenology %D 2013 %I %X We investigate the impact of heavy new physics on W bosons productions at hadron colliders using an effective field theory. After listing all the relevant dimension-six operators, their effects are computed taking into account LEP constraints. Additionally, the effective approach is compared to anomalous couplings regarding several issues like unitarity. %U http://arxiv.org/abs/1302.1112
