Three-loop anomalous dimensions of fixed-charge operators in the SM
A. V. Bednyakov
In this Letter we consider renormalization of a class of scalar operators with fixed hypercharge within the Standard Model. We carry out explicit computation of the correspondi…
Contribution of hadronic light-by-light scattering to the hyperfine structure of muonium
V. I. Korobov, A. V. Eskin, A. P. Martynenko +1
The contribution of hadronic scattering of light-by-light to the hyperfine structure of muonium is calculated using experimental data on the transition form factors of two photons…
Observation of the E(38)-boson
Kh. U. Abraamyan, A. B. Anisimov, M. I. Baznat +4
The first results of the search for the E(38)-boson are presented. The search was conducted in the effective mass spectra of photon pairs produced in the d(2.0 GeV/n) + C, d(3.0 Ge…
Resonance Structure in the Invariant Mass Spectrum in C- and C-Interactions
Kh. U. Abraamyan, M. I. Baznat, A. V. Friesen +10
Along with and mesons, a resonance structure in the invariant mass spectrum of two photons at MeV is observed in the reaction at…
