Physics of Neutrinos

In the last two years,reactor experiments corroborated in a conclusive manner previous hints supporting a very large value of ϑ13. Indeed the actual value of ϑ13 (sin2 2ϑ13 ≈ 0.09) turned out to be just below the previous limits from CHOOZ. Such highly fortunate outcome is bringing us to a complete reconsideration of the strategies to assess CP violation in the leptonic sector and determine...

We present in this contribution the extrapolation to very high energies of the theoretical cross sections, in proton-proton collisions, for the production of a 125 GeV Standard Model Higgs boson. The results are obtained using the same tools and framework defined in the two reports3 of the LHC Higgs Cross Sections Working Group.

We argue that if the LHC confirms that the properties of the recently discovered boson with the mass 124-126 GeV coincide with those of the Higgs boson of the Standard Model, and finds nothing else, a next step in high energy experimental physics should be the construction of an electron-positron or muon collider with a center of mass energy 200+200 GeV (Higgs and t-quark factory). This...

127. Searching for Dark Matter

We argue that in the situation when LHC discovers only the Higgs boson and finds no signatures of new physics (confirming thus the Standard Model) the necessity to explain the observed beyond-the-Standard-Model (BSM) phenomena, in particular neutrino masses, Dark Matter and matter-antimatter asymmetry of the Universe, should largely shape the further development of particle physics. We...

Having this facility built in Asia, before one considers how...
