Serpico at PPC-CERN: “Theoretical aspects of dark matter indirect detection”

“Dark Matter (DM) was already discovered indirectly: via gravity. But gravity is “universal” and does not permit particle identification: a discovery via electromagnetic, strong or weak probes is needed. The LHC at CERN was designed to study the electroweak (EW) scale, however there … Continue reading

Gunion in ArXiv: A 4th generation is ruled out if the SM Higgs has mass below 200 GeV

John F. Gunion (University of California, Davis) claims in “Ruling out a 4th generation using limits on hadron collider Higgs signals,” ArXiv, 19 May 2011, that the Tevatron and LHC data have essentially eliminated the possibility of a 4th generation … Continue reading

The future of the LHC at CERN

The Higgs agenda at CERN pass from Higgs discovery at the LHC (measure its mass and its width), to precision physics in the Higgs sector at the SLHC (measure cross sections x BR, ratios of couplings to particle, measure CP … Continue reading

Haber on “Present status and future prospects for a Higgs boson discovery”

“The electroweak symmetry breaking dynamics of the Minimal Standard Model (MSM) employs a self-interacting complex doublet of scalar fields, which consists of four real degrees of freedom.  Three of this four degrees of freedom has been already observed in the … Continue reading

Brumfiel in Nature, “Latest results from the LHC are casting doubt on the theory of supersymmetry”

“Supersymmetry is a theory that solves a host of problems with our understanding of the subatomic world, but there is growing anxiety that the theory, however elegant it might be, is wrong. Data from the Large Hadron Collider (LHC), a 27-kilometre … Continue reading
