Electromagnetic corrections in hadronic processes
In quantum field theory, the splitting of the Hamiltonian into a strong and an electromagnetic part cannot be performed in a unique manner. In the present article, we propose a convention for disentangling these two effects: one matches the parameters of two theories – with and without electromagnetic interactions – at a given scale μ1, referred to as the matching scale. This method enables one...
متن کاملHadronic processes and electromagnetic corrections
The inclusion of electromagnetism in a low energy effective theory is worth further study in view of the present high precision experiments (muon g − 2, π0 → γγ, τ decays, etc.). In particular in many applications of chiral perturbation theory, one has to purify physical matrix elements from electromagnetic effects. The theoretical problems that I want to point out here are following: the split...
متن کاملElectromagnetic Corrections in the Anomaly Sector
Chiral perturbation theory in the anomaly sector for Nf = 2 is extended to include dynamical photons, thereby allowing a complete treatment of isospin breaking. A minimal set of independent chiral lagrangian terms is determined and the divergence structure is worked out. There are contributions from irreducible and also from reducible one-loop graphs, a feature of ChPT at order larger than four...
متن کاملElectromagnetic Corrections in Staggered Chiral Perturbation Theory
To reduce errors in light-quark mass determinations, it is now necessary to consider electromagnetic contributions to light-meson masses. Calculations using staggered quarks and quenched photons are currently underway. Suitably-extended chiral perturbation theory is necessary to extrapolate the lattice data to the physical limit. Here we give (preliminary) results for light-meson masses using s...
متن کاملModel-independent QED corrections to photon structure-function measurements
We present the first calculation of QED radiative corrections to deep-inelastic electron–photon scattering in terms of those variables that are reconstructed in measurements of the photon structure function in electron– positron collisions. In order to cover the low-Q region, we do not invoke the QCD-improved parton model but rather express our results in terms of the photon structure functions...
