Prospects of Searches for the Higgs Boson at the LHC

  • Bruce Mellado


One of the most exciting prospects for the Large Hadron Collider is to observe the Higgs boson. The most important experimental characteristics of the two general-purpose detectors, the CMS and ATLAS experiments are summarised. The sensitivity for the CMS and ATLAS experiments at the LHC to discover a Standard Model Higgs boson with relatively low integrated luminosity per experiment is outlined. The most relevant discovery modes are covered. A brief discussion about the expected performance from these experiments in searches for one or more of the Higgs bosons from the minimal version of the supersymmetric theories is also included.
