description | This note describes the search for a Higgs boson decaying into
diphotons in pp collisions at the LHC at a center-of-mass
energy of 7~TeV.
Data-driven methods are used to evaluate the reconstruction and selection
performance for the signal, and the background is evaluated from a fit
to the data. The analysis is performed on a dataset corresponding to 4.8~fb$^{-1}$ of data
recorded in 2011 by the CMS experiment.
Limits are set on the cross section of a Standard Model Higgs boson
decaying to two photons.
The expected exclusion limit at 95\% CL is between 1.5 and 2.0 times
the Standard Model cross section in the mass range between 110 and
140~GeV/c$^{2}$, and the observed limit disfavours at 95\% CL a Standard Model
Higgs boson decaying into two photons in the mass range 127 to 131~GeV/c$^{2}$. |
