Two-loop QCD corrections to charged-Higgs-mediated $b \to s γ$ decay

P. Ciafaloni, A. Romanino, A. Strumia

The charged-Higgs-mediated contribution to the Wilson coefficient of the $b \to s γ$ magnetic penguin is expected to be one of the more promising candidates for a supersymmetric effe…

Quarkonium Photoproduction at Next-to-leading Order

F. Maltoni, M. L. Mangano, A. Petrelli

We present the calculation of O(as^2 aem) corrections to heavy-quarkonium total photoproduction cross-sections. Results are given for the colour-octet component of S and P waves. T…

Non-abelian flavour symmetry and R-parity

Gautam Bhattacharyya

If R-parity violation turns out to be a true aspect of Nature, a speculation about its possible origin could add a new dimension to the supersymmetric flavour problem. It has been…

NLO Production and Decay of Quarkonium

A. Petrelli, M. Cacciari, M. Greco +2

We present a calculation of next-to-leading-order (NLO) QCD corrections to total hadronic production cross sections and to light-hadron-decay rates of heavy quarkonium states. Both…

Atomic parity violation and the HERA anomaly

Leonardo Giusti, Alessandro Strumia

We show that the two scenarios able to explain the HERA anomaly --- a new leptoquark coupling or a new contact interaction --- predict new contributions to atomic parity violation.…

Distinguishing gauge-mediated from unified-supergravity spectra

Alessandro Strumia

We show that gauge-mediation and unified-supergravity give sufficiently firm and different predictions for the spectrum of supersymmetric particles to make it possible to discrimin…

The high-Q^2 Hera anomaly and supersymmetric unification

Riccardo Barbieri, Zurab Berezhiani, Alessandro Strumia

We discuss an initial condition on the superpotential couplings of an SU(5) theory which allows the R-violating term L d^c Q but avoids the simultaneous presence of L L e^c + d^c d…

CP violation in B decays and supersymmetry

Riccardo Barbieri, Alessandro Strumia

CP violation in hadronic B-decays is studied in a definite and well motivated framework of flavour physics and supersymmetry. Possible deviations from the standard model both in mi…

Penguin corrections and strong phases in a time-dependent analysis of $B_{d}^{0} \to π^{+} π^{-}$

Pier S. Marrocchesi, Nello Paver

From a time-dependent analysis of the decay $B_{d}^{0} \to π^{+} π^{-}$ and using a model-dependent $A_{P} / A_{T}$ ratio of the penguin-to-tree amplitudes contributing to the decay, both the…

Consequences of a U(2) Flavour Symmetry

Riccardo Barbieri, Lawrence J. Hall, Andrea Romanino

While solving the supersymmetric flavour problem, a U(2) flavour symmetry might be at the origin of the pattern of fermion masses and mixings. The consequences of this hypothesis a…

Unified theories of flavour with U(2) as horizontal group

Andrea Romanino

An unified flavour model based on U(2) as flavour group is described. Besides to explain the main characteristics of the fermion spectrum, the model is predictive and agrees quanti…
