Abstract:

This paper presents a search for Higgs bosons decaying to four leptons, either electrons or muons, via one or two light exotic gauge bosons Zd, H→ZZd→4 or H→ZdZd→4. The search was performed using pp collision data corresponding to an integrated luminosity of about 20 fb-1 at the center-of-mass energy of s=8 TeV recorded with the ATLAS detector at the Large Hadron Collider. The observed data are well described by the Standard Model prediction. Upper bounds on the branching ratio of H→ZZd→4 and on the kinetic mixing parameter between the Zd and the Standard Model hypercharge gauge boson are set in the range (1-9)×10-5 and (4-17)×10-2 respectively, at 95% confidence level assuming the Standard Model branching ratio of H→ZZ∗→4, for Zd masses between 15 and 55 GeV. Upper bounds on the effective mass mixing parameter between the Z and the Zd are also set using the branching ratio limits in the H→ZZd→4 search, and are in the range (1.5-8.7)×10-4 for 15
