Singular Inflation
John D. Barrow, Alexander A. H. Graham
We prove that a homogeneous and isotropic universe containing a scalar field with a power-law potential, , with and always develops a finite-time singula…
Impact of a Higgs boson at a mass of 126 GeV on the standard model with three and four fermion generations
Otto Eberhardt, Geoffrey Herbert, Heiko Lacker +4
We perform a comprehensive statistical analysis of the standard model (SM) with three and four generations using the latest Higgs search results from LHC and Tevatron, the electrow…
Status of the fourth fermion generation before ICHEP2012: Higgs data and electroweak precision observables
Otto Eberhardt, Alexander Lenz, Andreas Menzel +2
We perform a global fit of the parameters of the Standard Model with a sequential fourth generation (SM4) to LHC and Tevatron Higgs data and electroweak precision data. Using sever…
Joint analysis of Higgs decays and electroweak precision observables in the Standard Model with a sequential fourth generation
Otto Eberhardt, Geoffrey Herbert, Heiko Lacker +4
We analyse the impact of LHC and Tevatron Higgs data on the viability of the Standard Model with a sequential fourth generation (SM4), assuming Dirac neutrinos and a Higgs mass of…
Model-independent extraction of matrix elements from top-quark measurements at hadron colliders
H. Lacker, A. Menzel, F. Spettel +5
Current methods to extract the quark-mixing matrix element from single-top production measurements assume that : top quarks decay into $b…
Predictions of selected flavour observables within the Standard Model
J. Charles, O. Deschamps, S. Descotes-Genon +10
This letter gathers a selection of Standard Model predictions issued from the metrology of the CKM parameters performed by the CKMfitter group. The selection includes purely lepton…
Simultaneous Extraction of the Fermi constant and PMNS matrix elements in the presence of a fourth generation
Heiko Lacker, Andreas Menzel
Several recent studies performed on constraints of a fourth generation of quarks and leptons suffer from the ad-hoc assumption that 3 x 3 unitarity holds for the first three genera…
