Higgs mass implications on the stability of the electroweak vacuum
Joan Elias-Miro, Jose R. Espinosa, Gian F. Giudice +3
We update instability and metastability bounds of the Standard Model electroweak vacuum in view of the recent ATLAS and CMS Higgs results. For a Higgs mass in the range 124--126 Ge…
Anthropic solution to the magnetic muon anomaly: the charged see-saw
Kristjan Kannike, Martti Raidal, David M. Straub +1
We present models of new physics that can explain the muon g-2 anomaly in accord with with the assumption that the only scalar existing at the weak scale is the Higgs, as suggested…
Hints for a non-standard Higgs boson from the LHC
Martti Raidal, Alessandro Strumia
We reconsider Higgs boson invisible decays into Dark Matter in the light of recent Higgs searches at the LHC. Present hints in the CMS and ATLAS data favor a non-standard Higgs bos…
Interpreting OPERA results on superluminal neutrino
Gian F. Giudice, Sergey Sibiryakov, Alessandro Strumia
OPERA has claimed the discovery of superluminal propagation of neutrinos. We analyze the consistency of this claim with previous tests of special relativity. We find that reconcili…
Probing High-Scale and Split Supersymmetry with Higgs Mass Measurements
Gian F. Giudice, Alessandro Strumia
We study the range of Higgs masses predicted by High-Scale Supersymmetry and by Split Supersymmetry, using the matching condition for the Higgs quartic coupling determined by the m…
Implications of first LHC results
Alessandro Strumia
We discuss implications of first LHC results for models motivated by the hierarchy problem: large extra dimensions and supersymmetry. We present bounds, global fits and implication…
