Determining Triple Gauge Boson Couplings from Higgs Data

Abstract

In the framework of effective Lagrangians with the SU(2)_L x U(1)_Y symmetry linearly realized, modifications of the couplings of the Higgs field to the electroweak gauge bosons are related to anomalous triple gauge couplings (TGCs). Here, we show that the analysis of the latest Higgs boson production data at the LHC and Tevatron give rise to strong bounds on TGCs that are complementary to those from direct TGC analysis. We present the constraints on TGCs obtained by combining all available data on direct TGC studies and on Higgs production analysis. Note added: The analysis has been updated with all the public data available as November 2013. Updates of this analysis are provided at http://hep.if.usp.br/Higgs

5 pages, 1 figure. These results are based on the analysis of the Higgs couplings updated with all available data as November 2013, including the role of two additional operators. These updated results can be found at http://hep.if.usp.br/Higgs
