Abstract
at the Fermilab Tevatron at √ s = 1.96 TeV are presented. Hints of new physics observed in other SM measurements are also described. The Tevatron collider (USA) has been providing proton — anti proton collisions with a centre of mass energy of √ s = 1.96 TeV. In this article, results on searches for the Higgs boson as well as for the new physics performed by the two experiments, CDF and D0, using up to 9 fb −1 of integrated luminosity from the Tevatron Run II period (April 2002 – September 2011) are presented. §2. Standard model Higgs boson searches General search strategies for the Standard Model (SM) Higgs boson (and any other signatures) are: to maximise the selection of the Higgs boson signal, which is complimented by developing efficient object identification algorithms and by exploiting as many decay modes as possible; and to achieve the best discrimination against the backgrounds by improving the measurements of observables and the background modelling, by performing dedicated optimisation of selection and analysis methods for different sub-samples, and by employing multivariate techniques. In the standard model (SM), the Higgs boson decays with a highest branching
