چکیده

This report summarizes the latest experimental results on radiative and electroweak rare B meson decays. These rare decay processes proceed through the Flavor-Changing-Neutral-Current processes, and thus are sensitive to the postulated new particles in the theories beyond the Standard Model. Experiments at e + e − colliders, Belle, BaBar and CLEO, have been playing the dominant role, while the CDF and D0 experiments have just started to provide new results from Tevatron Run-II. The most significant achievement is the first observation of the decay B → K * ℓ + ℓ − , which opens a new window to search for new physics in B meson decays.

An alternative calculation of the lowest order electroweak radiative corrections (EWC) to the single W-boson production in hadron-hadron collision in the framework of the quark parton model without any absorption of the collinear quark singularity into the parton distributions is carried out. Numerical analysis under Tevatron and LHC kinematic conditions is performed.

The bosonic two-loop electroweak radiative corrections to the muon’s anomalous magnetic moment, aμ ≡ (gμ − 2)/2, are presented. We find ∆a μ (2 loop bosonic)/a EW μ (1 loop) ≈ απ (

Semileptonic and radiative beauty decays play an important role in the determination of the CKM matrix elements and in the indirect search for new physics: the former, tree-level dominated, allow for a precise measurement of the CKM elements Vcb and Vub; the latter, loop-induced, are directly sensitive to new physics contributions, and give also information on Vtd and Vts. These decay modes, al...

We analyze the degree to which parity-violating (PV) electroexcitation of the ∆(1232) resonance may be used to extract the weak neutral axial vector transition form factors. We find that the axial vector electroweak radiative corrections are large and theoretically uncertain, thereby modifying the nominal interpretation of the PV asymmetry in terms of the weak neutral form factors. We also show...

However, there are many probes of physics beyond the SM at scales ranging from a few to tens of TeV. In particular, four-fermion operators that give rise to new electroweak contributions generally constrain the new physics scale to be more than a few TeV, and some new flavorchanging four-fermion operators are constrained even further, to be above the tens of TeV level. With mounting evidence1 f...
