Abstract:

A search for the decays of the Higgs and Z bosons to J/ψγ and γ(nS)γ (n=1,2,3) is performed with pp collision data samples corresponding to integrated luminosities of up to 20.3 fb-1 collected at s=8 TeV with the ATLAS detector at the CERN Large Hadron Collider. No significant excess of events is observed above expected backgrounds and 95% C.L. upper limits are placed on the branching fractions. In the J/ψγ final state the limits are 1.5×10-3 and 2.6×10-6 for the Higgs and Z boson decays, respectively, while in the γ(1S,2S,3S)γ final states the limits are (1.3,1.9,1.3)×10-3 and (3.4,6.5,5.4)×10-6, respectively. © 2015 CERN. for the ATLAS Collaboration.

  • ATLAS uses a right-handed coordinate system with its origin at the nominal interaction point (IP) in the center of the detector and the (Equation presented) axis along the beam pipe. The (Equation presented) axis points from the IP to the center of the LHC ring, and the (Equation presented) axis points upward. Cylindrical coordinates ((Equation presented)) are used in the transverse plane, (Equation presented) being the azimuthal angle around the beam pipe. The pseudorapidity is defined in terms of the polar angle (Equation presented) as (Equation presented); (2008) JINST, 3, p. S08003. , ATLAS Collaboration,.
