The anomalous magnetic moment of the muon in the Standard Model
T. Aoyama, N. Asmussen, M. Benayoun +129
We review the present status of the Standard Model calculation of the anomalous magnetic moment of the muon. This is performed in a perturbative expansion in the fine-structure con…
Low energy doubly-virtual Compton scattering from di-lepton electroproduction on a nucleon
Vladyslav Pauk, Carl E. Carlson, Marc Vanderhaeghen
We propose a new way to experimentally determine the subleading low-energy structure constant of doubly-virtual Compton scattering on a proton. Such empirical determination will re…
Determination of the pole position of the lightest hybrid meson candidate
JPAC Collaboration, A. Rodas, A. Pilloni +9
Mapping states with explicit gluonic degrees of freedom in the light sector is a challenge, and has led to controversies in the past. In particular, the experiments have reported t…
Dilepton photoproduction on a deuteron target
Carl E. Carlson, Vladyslav Pauk, Marc Vanderhaeghen
We investigate the sensitivity of the cross section for lepton pair production off a deuteron target, , to the deuteron charge radius. We show that for small mome…
Analyticity Constraints for Hadron Amplitudes: Going High to Heal Low Energy Issues
JPAC Collaboration, V. Mathieu, J. Nys +7
Analyticity constitutes a rigid constraint on hadron scattering amplitudes. This property is used to relate models in different energy regimes. Using meson photoproduction as a ben…
Beam normal spin asymmetry for the process
Carl E. Carlson, Barbara Pasquini, Vladyslav Pauk +1
We calculate the single spin asymmetry for the process, for an electron beam polarized normal to the scattering plane. Such single spin asymmetries vanish in th…
New analysis of tensor resonances measured at the COMPASS experiment
A. Jackura, C. Fernandez-Ramirez, M. Mikhasenko +232
We present a new amplitude analysis of the -wave in measured by COMPASS. Employing an analytical model based on the principles of the relativistic -mat…
Lepton universality test in the photoproduction of versus pairs on a proton target
Vladyslav Pauk, Marc Vanderhaeghen
In view of the significantly different proton charge radius extracted from muonic hydrogen Lamb shift measurements as compared to electronic hydrogen spectroscopy or electron scatt…
Anomalous magnetic moment of the muon in a dispersive approach
Vladyslav Pauk, Marc Vanderhaeghen
We present a new general dispersive formalism for evaluating the hadronic light-by-light scattering contribution to the anomalous magnetic moment of the muon. In the suggested appr…
Two-loop massive scalar three-point function in a dispersive approach
Vladyslav Pauk, Marc Vanderhaeghen
We present a dispersion relation formalism to calculate a massive scalar two-loop vertex function. Such calculation is of direct relevance in the evaluation of the hadronic light-b…
Single meson contributions to the muon's anomalous magnetic moment
Vladyslav Pauk, Marc Vanderhaeghen
We develop the formalism to provide an improved estimate for the hadronic light-by-light correction to the muon's anomalous magnetic moment a_μ, by considering single meson contrib…
Analytic structure of theory using light-by-light sum rules
V. Pauk, V. Pascalutsa, M. Vanderhaeghen
We apply a sum rule for the forward light-by-light scattering process within the context of the quantum field theory. As a consequence of the sum rule a stringent causality c…
Light-by-light scattering sum rules constraining meson transition form factors
Vladimir Pascalutsa, Vladyslav Pauk, Marc Vanderhaeghen
Relating the forward light-by-light scattering to energy weighted integrals of the γ* γ-fusion cross sections, with one real photon (γ) and one virtual photon (γ*), we find two new…
Sum rules for hadronic contributions to low-energy light-by-light scattering
Vladimir Pascalutsa, Vladyslav Pauk, Marc Vanderhaeghen
We present a set of sum rules relating the low-energy light-by-light scattering to integrals of γγ-fusion cross sections and use them to study the hadronic contributions.

Inclusive distributions in the unitarized pomeron models
A. Alkin, E. Martynov, V. Pauk +1
High energy inclusive hadron production in the central kinematical region is analyzed within the models of unitarized pomeron. It is shown that the sum of multipomeron exchanges wi…
