Updated measurements of the Higgs-like boson at 125 GeV in the two photon decay channel


Table of contents:

Abstract

Results are reported from a search for the standard model Higgs boson in the two photon channel in the mass range 110 < mH < 150 GeV, using the full dataset recorded by the CMS experiment at the LHC from pp collisions at centre-of-mass energies of 7 and 8 TeV. The most sensitive, MVA, analysis observes an excess of events at a mass of 125 GeV, with a local significance of 3.2σ (standard deviations), where a local significance of 4.2σ is expected from a standard model Higgs boson. The best-fit signal strength, σ/σSM, is 0.780.27 at mH=125 GeV, and the mass is fitted to be 125.4 0.5(stat.) 0.6(syst.). The cut-based analysis observes a corresponding excess with a local significance of 3.9σ (3.5σ expected), and σ/σSM=1.110.31 at mH=124.5 GeV. All measurements are compatible among themselves and with a Higgs boson with a mass of 125.4 GeV.

Compatibility between the mass-fit MVA and the cut-based analyses

  • Low signal to background ratio a fundamental feature of the H→γγ channel. Uncertainty on the signal strength driven by statistical fluctuations of the background, and analysis changes can lead to statistical changes due to fluctuations of which events are selected, and their fluctuations of their mass (recalibration etc.).
  • The correlation coefficient between the MVA and cut-based signal strength measurements is found to be r=0.76 (estimated using jackknife techniques).
  • Taking account of the correlation, the compatibility between the MVA and cut-based analysis measurements of the signal strength is found to be within 1.5σ for the combined 7 and 8 TeV measurement, and within 1.8σ for the 8 TeV measurement alone.

Event overlap between the mass-fit MVA and the cut-based analyses

The overlap of the events selected by the two analyses. The overlap of signal events (MC) is much higher than the overlap of background events (as seen in data and background MC).

Mass measurement

Figure Description

pdf : png
The 1D test statistic 2 ln Q vs Higgs boson mass hypothesis, mH. The solid line is obtained with all nuisance parameters profiled and so includes both statistical and systematic uncertainties. The dashed line is obtained with all nuisance parameters fixed to their best-fit values and thus includes only statistical uncertainties. The crossings with the thick (thin) horizontal lines define the 68% (95%) CL interval for the measured mass. Two reduce model-dependency, two production cross-section scaling factors (μgg+ttH and μ VBF+VH) are introduced as nuisance parameters and profiled in this measurement.

Monte Carlo description of mγγ

Figure Description

pdf : png
Diphoton mass distribution for data (data points), and Monte Carlo simulation of SM processes which constitute the background to the search (histograms) for the 2012 8 TeV data sample. A simulated signal for a Higgs boson with a mass of 125 GeV is shown by the red outline histogram. The selection of the data and simulated events corresponds to the mass-fit MVA analyisis. The magnitude of the signal is what would be expected if its cross section were five times the SM expectation.The shaded band represents the theoretical (k-factor) uncertainty on the the MC prediction.
Note that in the analysis the background is evaluated from a fit to the data without reference to the MC simulation.

The nominal MVA output is shown as the stacked histogram (where the contributions are from different production processes), and the variation due to the shape variation resulting from propagating the systematic uncertainty assigned to the photon ID MVA score is shown as a blue hatched band. The MVA event class boundaries are shown as vertical dotted lines; events with an MVA score of less than -0.05 are discarded from the analysis.

The Z boson mass peak is shown for events with both electromagnetic showers in the best energy resolution categories: both with R9>0.94, and both in the central region of the ECAL barrel, |η|<1.0.

The data/MC agreement is excellent.

Comparison of the reconstructed mass in Z→ee events in data and Monte Carlo where the electrons are reconstructed as photons, and the events are selected (with the electron veto condition inverted) and categorized as diphoton events are selected and categorized in the mass-fit MVA analysis. The Z boson mass peak is shown for events in the four inclusive categories.

The data/MC agreement is excellent in all the four categories.

The Z boson mass peak is shown for events in three bins of Nvtx.

The data/MC agreement is excellent irrespective of pileup.

Comparison of the diphoton MVA output for Z→ee events in data and Monte Carlo where the electrons are reconstructed as photons, for events passing the pre-selection of the mass-fit MVA analysis (with the electron veto condition inverted). Corrections have been applied to the MVA inputs for MC. The systematic uncertainty resulting from propagating to the diphoton MVA the uncertainty assigned to the photon identification MVA score (which corresponds to a shift of 0.01 of the MVA score) is indicated by the hatched band. The MC has been reweighted to match the Z boson pT distribution observed in data.
