Bloch-Nordsieck cancellations beyond logarithms in heavy particle decays.
We investigate the one-loop radiative corrections to the semileptonic decay of a charged particle at finite gauge boson mass. Extending the Bloch-Nordsieck cancellation of infrared logarithms, the subsequent non-analytic terms are also found to vanish after eliminating the pole mass in favor of a mass defined at short distances. This observation justifies the operator product expansion for incl...
متن کاملDecays Beyond Leading Logarithms
Using the next-to-leading order low energy effective Hamiltonian for |∆B| = 1, ∆C = ∆U = 0 transitions, the contributions of electroweak penguin operators in B−(B0 d) → PP and PV decays are estimated in the standard model. We find that, for some channels, the electroweak penguin effects can enhance or reduce the QCD penguin and/or tree level contributions by at least 30%, and can even play domi...
متن کاملWeak Decays beyond Leading Logarithms
We review the present status of QCD corrections to weak decays beyond the leading logarithmic approximation including particle-antiparticle mixing and rare and CP violating decays. After presenting the basic formalism for these calculations we discuss in detail the effective hamiltonians for all decays for which the next-to-leading corrections are known. Subsequently, we present the phenomenolo...
متن کاملLifetimes of heavy hadrons beyond leading logarithms
The lifetime splitting between the B and B d mesons has recently been calculated in the next-to-leading order of QCD. These corrections are necessary for a reliable theoretical prediction, in particular for the meaningful use of hadronic matrix elements computed with lattice QCD. Using results from quenched lattice QCD we find τ (B)/τ (B d) = 1.053 ± 0.016 ± 0.017, where the uncertainties from ...
متن کاملThe Bloch-nordsieck Propagator at Finite Temperature
We have shown recently that the resummation of soft photon contributions leads to a non-exponential decay of the fermion excitations in hot QED plasmas. The retarded propagator of a massless fermion was found to behave as SR(t 1/gT ) ∼ exp{−αTt [ lnωpt+C]}, where ωp = gT/3 is the plasma frequency, α = g2/4π, and C is a constant, independent of g, which was left undefined. This term is computed ...
