Tensor-structure sum rules for spin-1 targets at all
Vladimir Pascalutsa, Marc Vanderhaeghen
We derive a family of sum rules for the tensor structure functions of targets with spin one or higher, rooted in exact Siegert relations. The mixed rank-two -- degeneracy c…
Lepton non-universality of hadronic contributions and a sub-GeV window to New Physics
Siyuan Li, Vladimir Pascalutsa, Maxim Pospelov
We propose the linear combination of the anomalous magnetic moments of the muon and electron, , as a natural low-energy window quantity that ma…
Field-theoretic versus data-driven evaluations of electromagnetic corrections to hadronic vacuum polarization in
Volodymyr Biloshytskyi, Dominik Erb, Harvey B. Meyer +2
The Standard Model prediction of the muon increasingly depends on lattice QCD computations of the hadronic vacuum polarization (HVP), where the isospin-breaking (IB) effects…
The QED of Bernabéu-Tarrach sumrule for electric polarizability and its implication for the Lamb shift
Volodymyr Biloshytskyi, Iulian Ciobotaru-Hriscu, Franziska Hagelstein +2
We attempt to rehabilitate a sum rule (proposed long ago by Bernabéu and Tarrach) which relates the electric polarizability of a particle to the total photoabsorption of quasi-real…
Two-photon decay of fully-charmed tetraquarks from light-by-light scattering at the LHC
Volodymyr Biloshytskyi, Lucian Harland-Lang, Bogdan Malaescu +3
The LHC newly-discovered resonant structures around 7 GeV, such as the , could be responsible for the observed excess in light-by-light scattering between 5 and 10 GeV. We…
Theoretical discrepancies in the nucleon spin structure and the hyperfine splitting of muonic hydrogen
Vladimir Pascalutsa, Franziska Hagelstein, Vadim Lensky
Two groups, ours (Mainz) and Bochum, have recently been re-evaluating the spin polarizabilities and spin structure functions at low , using the baryon chiral perturbation theory…
