The search for the Higgs boson and the W boson mass measurement at the Tevatron
The experimental confirmation of the Higgs boson existence is one of the main goals of the elementary particle physics today, since its existence would help explain the origin of mass of the elementary particles. Higgs boson mass itself dictates the properties of Higgs boson production and decay, but it is a free parameter of the Standard model, it has to be determined by experiment. The Tevatron hadron collider at Fermilab has been successfully producing collisions of particles with high enough energies to produce certain types of Higgs bosons. The methods used to search for Higgs bosons at the Tevatron will be presented together with their newest results.
The Higgs boson mass indirectly affects the mass of the W boson. The presented measurement of the W mass is, due to the required precision, one of the most challenging measurements at the Tevatron experiments. It constrains the range of possible Higgs boson masses and would, in case the Higgs boson is experimentally confirmed, check the inner consistency of the Standard model predictions.
