ATLAS-CMS Higgs Boson: Combined Production and Decay Measurements from LHC Collisions

A combined ATLAS and CMS analysis presents measurements of Higgs boson production and decay rates, along with constraints on its couplings. The analysis uses proton-proton collision data from the CERN LHC recorded in 2011 and 2012, corresponding to integrated luminosities of approximately 5 fb⁻¹ at 7 TeV and 20 fb⁻¹ at 8 TeV per experiment. Results are reported assuming a Higgs boson mass of 125.09 GeV and are consistent with Standard Model predictions.

Use Cases

• Constraining Higgs boson coupling modifiers based on combined cross-section and branching fraction measurements.
• Testing Standard Model predictions against observed significances for specific production and decay processes.
• Comparing Higgs boson signal yield relative to theoretical expectations across different parameterisations.
• Analyzing Higgs boson interactions with vector bosons and fermions based on the five production and six decay channels studied.

Strengths

• Combined analysis from two major LHC experiments (ATLAS and CMS), increasing statistical power.
• Data from two collision energy levels (7 TeV and 8 TeV) with specified integrated luminosities.
• Analysis covers five Higgs production processes and six decay modes, providing a multi-channel view.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
