Descripción
A search is presented for the production of two Higgs bosons in final
states containing two photons and two bottom quarks. Both resonant and
nonresonant hypotheses are investigated. The analyzed data correspond to
an integrated luminosity of 19.7 fb-1 of proton-proton
collisions at √{s }=8 TeV collected with the CMS detector. Good
agreement is observed between data and predictions of the standard model
(SM). Upper limits are set at 95% confidence level on the production
cross section of new particles and compared to the prediction for the
existence of a warped extra dimension. When the decay to two Higgs
bosons is kinematically allowed, assuming a mass scale
ΛR=1 TeV for the model, the data exclude a radion
scalar at masses below 980 GeV. The first Kaluza-Klein excitation mode
of the graviton in the RS1 Randall-Sundrum model is excluded for masses
between 325 and 450 GeV. An upper limit of 0.71 pb is set on the
nonresonant two-Higgs-boson cross section in the SM-like hypothesis.
Limits are also derived on nonresonant production assuming anomalous
Higgs-boson couplings.
