Particle Physics and Cosmology
  Today, both particle physics and cosmology are described by few parameter
Standard Models, i.e. it is possible to deduce consequence of particle physics
in cosmology and vice verse. The former is examined in this lecture, in light
of the recent systematic exploration of the electroweak scale by the LHC
experiments. The two main results of the first phase of the LHC, the discovery
of a Higgs-like particle and the absence so far of new particles predicted by
"natural" theories beyond the Standard Model (supersymmetry, extra-dimension
and composite Higgs) are put in a historical context to enlighten their
importance and then presented extensively. To be complete, a short review from
the neutrino physics, which can not be probed at LHC, is also given. The
ability of all these results to resolve the 3 fundamental questions of
cosmology about the nature of dark energy and dark matter as well as the origin
of matter-antimatter asymmetry is discussed in each case.
