Abstract | This note presents a combination of published and preliminary measurements of triple gauge boson couplings (TGCs) and quartic gauge boson couplings (QGCs) from the four LEP experiments. We combine the charged TGCs g^Z_1, kappa_gamma and lambda_gamma in single and mulit-parameter fits for the first time since the inclusion of O(alpha_em) corrections to the WW production process in Monte carlo simulations. The QGCs from the ZZgammagamma vertex, a_c/Lambda^2 and a_0/Lambda^2, are combined as well. The combinations of neutral TGCs h^V_i and f^V_i are also included. |
