Description

The Large Hadron Collider at CERN presents an unprecedented opportunity to probe the realm of New Physics in the TeV region and shed light on some of the core unresolved issues of Particle Physics. These include the nature of electroweak symmetry breaking, the origin of mass, the possible constituent of cold Dark Matter, new sources of CP violation needed to explain the baryon excess in the Universe, the possible existence of extra gauge groups and extra matter, and importantly the path Nature chooses to resolve the hierarchy problem - is it Supersymmetry or Extra Dimensions. Many models of New Physics beyond the Standard Model contain a hidden sector which can be probed at the LHC. Additionally, the LHC will be a top-quark factory and accurate measurements of the properties of the top-quark and its rare decays will provide a window to New Physics. An overview of these possibilities will be given in the lecture.
