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…
Model-independent constraints on new physics in b --> s transitions
Wolfgang Altmannshofer, Paride Paradisi, David M. Straub
We provide a comprehensive model-independent analysis of rare decays involving the b --> s transition to put constraints on dimension-six Delta(F)=1 effective operators. The constr…
U(2) and MFV in Supersymmetry
David M. Straub
A suitably broken U(2)^3 symmetry acting on the first two generations of quarks and squarks is studied as a natural generalization of the Minimal Flavour Violation principle to the…
B-decay CP-asymmetries in SUSY with a U(2)^3 flavour symmetry
Riccardo Barbieri, Paolo Campli, Gino Isidori +2
We study CP asymmetries in rare B decays within supersymmetry with a U(2)^3 flavour symmetry, motivated by the SUSY flavour and CP problems, the hierarchies in the Yukawa couplings…
New physics searches in flavour physics
David M. Straub
The origin of flavour and CP violation is among the most important open questions in particle physics. Imminent results from the LHC as well as planned dedicated flavour physics ex…
Direct detection and CMB constraints on light DM scenario of top quark asymmetry and dijet excess at Tevatron
Andi Hektor, Gert Hütsi, Mario Kadastik +3
We study in detail the model by Isidori and Kamenik that is claimed to explain the top quark forward-backward asymmetry at Tevatron, provide GeV-scale dark matter (DM), and possibl…
U(2) and Minimal Flavour Violation in Supersymmetry
Riccardo Barbieri, Gino Isidori, Joel Jones-Perez +2
Rather than sticking to the full approximate symmetry normally invoked in Minimal Flavour Violation, we analyze the consequences on the current flavour data of a suitably…
CP Violation in Supersymmetry with Effective Minimal Flavour Violation
Riccardo Barbieri, Paolo Lodone, David M. Straub
We analyze CP violation in supersymmetry with Effective Minimal Flavour Violation, as recently proposed in arXiv:1011.0730. Unlike the case of standard Minimal Flavour Violation, w…
New physics correlations in rare decays
David M. Straub
This talk gives an overview of correlations between new physics effects in rare B and K decays arising in concrete models or on a model-independent basis and discusses how these co…
