Footprints of SUSY GUTs in Flavour Physics
Andrzej J. Buras, Minoru Nagai, Paride Paradisi
Supersymmetric (SUSY) Grand Unified theories (GUTs) generally predict FCNC and CP violating processes to occur both in the leptonic and hadronic sectors. Assuming an underlying SU(…
Flavour Theory and the LHC Era
Andrzej J. Buras
This decade should make a significant progress towards the Theory of Flavour and the main goal of this talk is to transfer this believe to my colleagues in the particle physics com…
EDMs vs. CPV in B_{s,d} mixing in two Higgs doublet models with MFV
Andrzej J. Buras, Gino Isidori, Paride Paradisi
We analyze the correlations between electric dipole moments (EDMs) of the neutron and heavy atoms and CP violation in B_{s,d} mixing in two Higgs doublet models respecting the Mini…
Quark flavour mixing with right-handed currents: an effective theory approach
Andrzej J. Buras, Katrin Gemmler, Gino Isidori
The impact of right-handed currents in both charged- and neutral-current flavour-violating processes is analysed by means of an effective theory approach. More explicitly, we analy…
Lepton Flavour Violation in the Presence of a Fourth Generation of Quarks and Leptons
Andrzej J. Buras, Björn Duling, Thorsten Feldmann +2
We calculate the rates for the charged lepton flavour violating (LFV) decays l_i -> l_j gamma, tau -> l pi, tau -> l eta('), mu^- -> e^-e^+e^-, the six three-body leptonic decays t…
Higgs-mediated FCNCs: Natural Flavour Conservation vs. Minimal Flavour Violation
Andrzej J. Buras, Maria Valentina Carlucci, Stefania Gori +1
We compare the effectiveness of two hypotheses, Natural Flavour Conservation (NFC) and Minimal Flavour Violation (MFV), in suppressing the strength of flavour-changing neutral-curr…
The Impact of a 4th Generation on Mixing and CP Violation in the Charm System
Andrzej J. Buras, Björn Duling, Thorsten Feldmann +3
We study D0-D0 mixing in the presence of a fourth generation of quarks. In particular, we calculate the size of the allowed CP violation which is found at the observable level well…
Patterns of Flavour Violation in the Presence of a Fourth Generation of Quarks and Leptons
Andrzej J. Buras, Björn Duling, Thorsten Feldmann +3
We calculate a number of observables related to particle-antiparticle mixing and the branching ratios for the most interesting rare and CP-violating K and B decays in the Standard…
A Lower Bound on hadronic EDMs from CP Violation in D0-D0bar mixing in SUSY Alignment Models
Wolfgang Altmannshofer, Andrzej J. Buras, Paride Paradisi
The SM predictions for CP violating effects in D meson systems are highly suppressed at the per mill level. Therefore, any experimental evidence for a sizable CP violation in D0-D0…
