Light axigluon explanation of the Tevatron ttbar asymmetry and multijet signals at the LHC

Christian Gross, Gustavo Marques Tavares, Martin Schmaltz +1

The ttbar asymmetry measured at the Tevatron continues to disagree with Standard Model predictions at the 3 sigma level. We update the status of the phenomenological light axigluon…

Naturalness of the Non-Universal MSSM in the light of the recent Higgs results

Stefan Antusch, Lorenzo Calibbi, Vinzenz Maurer +2

We analyse the naturalness of the Minimal Supersymmetric Standard Model (MSSM) in the light of recent LHC results from the ATLAS and CMS experiments. We study non-universal boundar…

Kähler-driven Tribrid Inflation

Stefan Antusch, David Nolde

We discuss a new class of tribrid inflation models in supergravity, where the shape of the inflaton potential is dominated by effects from the Kähler potential. Tribrid inflation i…

Squark Flavor Implications from B --> K(*) l+ l-

Arnd Behring, Christian Gross, Gudrun Hiller +1

Recent experimental and theoretical progress regarding B --> K(*) l+ l- decays led to improved bounds on the Wilson coefficients C_9 and C_10 of four-fermion operators of the |Delt…

θ^PMNS_13 = θ_C / \sqrt2 from GUTs

Stefan Antusch, Christian Gross, Vinzenz Maurer +1

The recent observations of the leptonic mixing angle θ^PMNS_13 are consistent with θ^PMNS_13 = θ_C / \sqrt2 (with θ_C being the Cabibbo angle θ^CKM_12). We discuss how this relatio…

Pseudosmooth Tribrid Inflation

Stefan Antusch, David Nolde, Mansoor Ur Rehman

We explore a new class of supersymmetric models of inflation where the inflaton is realised as a combination of a Higgs field and (gauge non-singlet) matter fields, using a "tribri…

Simplified Smooth Inflation with Observable Gravity Waves

Mansoor Ur Rehman, Qaisar Shafi

We consider a simplified version of supersymmetric smooth hybrid inflation which contains a single ultraviolet cutoff m_P = 2.4 x 10^{18} GeV, instead of the two cutoffs m_P and M_…
