Query: Search for the standard model Higgs boson in the decay channel H to ZZ
  to 4 leptons in pp collisions at sqrt(s) = 7 TeV   A search for a Higgs boson in the four-lepton decay channel H to ZZ, with
each Z boson decaying to an electron or muon pair, is reported. The search
covers Higgs boson mass hypotheses in the range 110 < mH < 600 GeV. The
analysis uses data corresponding to an integrated luminosity of 4.7 inverse
femtobarns recorded by the CMS detector in pp collisions at sqrt(s) = 7 TeV
from the LHC. Seventy-two events are observed with four-lepton invariant mass
m[4 leptons] > 100 GeV (with thirteen below 160 GeV), while 67.1 +/- 6.0 (9.5
+/-1.3) events are expected from background. The four-lepton mass distribution
is consistent with the expectation of standard model background production of
ZZ pairs. Upper limits at 95% confidence level exclude the standard model Higgs
boson in the ranges 134-158 GeV, 180-305 GeV, and 340 -465 GeV. Small excesses
of events are observed around masses of 119, 126, and 320 GeV, making the
observed limits weaker than expected in the absence of a signal.
