Implications of effective axial-vector coupling of gluon for spin polarizations at the LHC
E. Gabrielli, A. Racioppi, M. Raidal +1
We analyze the impact of effective axial-vector coupling of the gluon on spin polarization observables in pair production at the LHC. Working at leading order in QCD, we…
Scalar Singlet Dark Matter
Geneviève Bélanger, Kristjan Kannike, Alexander Pukhov +1
We consider the minimal scalar singlet dark matter stabilised by a symmetry. Due to the cubic term in the scalar potential, semi-annihilations, besides annihilations, contrib…
Is the resonance at 125 GeV the Higgs boson?
Pier Paolo Giardino, Kristjan Kannike, Martti Raidal +1
The recently discovered resonance at 125 GeV has properties remarkably close to those of the Standard Model Higgs boson. We perform model-independent fits of all presently availabl…
Fermi 130 GeV gamma-ray excess and dark matter annihilation in sub-haloes and in the Galactic centre
Elmo Tempel, Andi Hektor, Martti Raidal
We analyze publicly available Fermi-LAT high-energy gamma-ray data and confirm the existence of clear spectral feature peaked at E=130GeV. Scanning over the Galaxy we identify seve…
Les Houches 2011: Physics at TeV Colliders New Physics Working Group Report
G. Brooijmans, B. Gripaios, F. Moortgat +141
We present the activities of the "New Physics" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 30 May-17 June, 2011). Our report includes new agreem…
Fermiophobic Higgs boson and supersymmetry
Emidio Gabrielli, Kristjan Kannike, Barbara Mele +2
If a light Higgs boson with mass 125 GeV is fermiophobic, or partially fermiophobic, then the MSSM is excluded. The minimal supersymmetric fermiophobic Higgs scenario can naturally…
