It is expected that it will address the most fundamental questions of physics, hopefully allowing progress in understanding the deepest laws of nature. Mainly:
* Is the Higgs mechanism for generating elementary particle masses via electroweak symmetry breaking indeed realised in nature?
* Is supersymmetry, an extension of the Standard Model and Poincaré symmetry, realised in nature, implying that all known particles have supersymmetric partners?
* Are there extra dimensions, as predicted by various models inspired by string theory, and can we detect them?
