Le séminaire "The ongoing hunt for new Physics at the LHC" se déroulera à 10h30, amphithéâtre Bloch (IPht, CEA Ormedes Merisiers).
In the past 20 years, the Standard Model (SM) of elementary particles and their
interactions has provided an unfailing description of all experimental observations at
energy scales of 100 GeV.
The Large Hadron Collider of CERN was conceived to probe the physics of the TeV energy
scale, providing a definitive statement on the infamous Higgs boson of the SM, but also
looking for “new physics”. And whereas the discovery of a Higgs boson in 2012 has
completed the SM, there are several indications that such physics “beyond the SM”
The possibilities are a testament to human ingenuity : from supersymmetry, which may
blur the distinction between matter and force, to extra dimensions, which may provide
the missing link between the standard model and gravity, there are numerous
hypothesized new signals to search for. The LHC experiments are currently combing
through their data samples looking for these new phenomena, and more. The talk will
present a broad-brush picture of “the why, the what and the how” the searches are
carried out, along with highlights of current results and the reasons for which
expectations remain very high.
