Understanding production cross-sections and their evolution as a function of √s are important components to understanding the measurements performed by ATLAS.
The energies of particles can be measured with the CMS electromagnetic and hadronic calorimeters without a magnet.
The two most accurate determinations of the angle, carried out at LEP and SLD, are some three standard deviations different.
The combined signal yield relative to the Standard Model expectation is measured to be 1.09±0.11.
The measured cross-sections are also used to place the most stringent limits to date on models of new physics employing any of four different dimension-six operators.
The results reveal an observed (expected) significance of the signal of 2.2 (0.8)σ, for a Higgs-boson mass of 125 GeV.
Recently published studies concern the decays of the Higgs boson into vector bosons and fermions in various production modes.
The search for heavy particles beyond the direct reach of the LHC.
