Hadron Structure in Chiral Perturbation Theory
A. Aleksejevs, S. Barkanova
We present our predictions for meson form factors for the SU(3) octet and investigate their impact on the pion electroproduction cross sections. The electric and magnetic polarizab…
Dynamic Structure of Hadrons in ChPT
A. Aleksejevs, S. Barkanova
The Chiral Perturbation Theory (ChPT) has been very successful in describing low-energy hadronic properties in the non-perturbative regime of Quantum Chromodynamics. The results of…
Dimensional Regularization and Dispersive Two-Loop Calculations
A. Aleksejevs, S. Barkanova
The two-loop contributions are now often required by the precision experiments, yet are hard to express analytically while keeping precision. One way to approach this challenging t…
Dispersive Two-Loop Calculations: Methodology and Applications
A. Aleksejevs, S. Barkanova
As the new-generation precision experiments such as MOLLER and P2 look for physics beyond Standard Model, it is becoming increasingly important to evaluate the higher-order electro…
Two Photon Exchange for Exclusive Pion Electroproduction
A. Afanasev, A. Aleksejevs, S. Barkanova
We perform detailed calculations of two-photon-exchange QED corrections to the cross section of pion electroproduction. The results are obtained with and without the soft-photon ap…
One-loop electroweak corrections for polarized Moller scattering at different renormalization schemes and conditions
A. Aleksejevs, S. Barkanova, A. Ilyichev +2
Using two different approaches, we perform updated and detailed calculations of the complete one-loop (Next-to-Leading Order (NLO)) set of electroweak radiative corrections to the…
