Subtracted Dispersion Relations for Virtual Compton Scattering off the Proton
I. Danilkin, B. Pasquini, M. Ronchi +1
We present a once-subtracted dispersion relation (DR) formalism for the virtual Compton scattering (VCS) process from threshold up to the energy region. The formalism aim…
Dispersive analysis of the process
Bai-Long Hoid, Igor Danilkin, Marc Vanderhaeghen
We present an analysis of the radiative decay in a dispersive framework, where the two-pion subsystem undergoes strong final-state interactions that cover the $f_0(…
New Physics Searches via Beam Normal Spin Asymmetry in Bhabha Scattering
Aleksandr Pustyntsev, Muthubharathi S. Ramasamy, Marc Vanderhaeghen
We examine the sensitivity of the beam normal spin asymmetry in Bhabha scattering to beyond the Standard Model (BSM) mediators, in the context of the JLab polarized positron progra…
Implications of recent measurements for MeV-GeV dark sector searches
Aleksandr Pustyntsev, Marc Vanderhaeghen
Recent theoretical and experimental studies of the muon magnetic moment indicate the absence of the previously reported discrepancy, providing a vital opportunity to constrain pote…
The anomalous magnetic moment of the muon in the Standard Model: an update
R. Aliberti, T. Aoyama, E. Balzani +232
We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, , updating the first White Paper (WP20) [1]. The pure QED and electroweak contrib…
The all-charm tetraquark and its contribution to two-photon processes
Panagiotis Kalamidas, Marc Vanderhaeghen
Prompted by several potential tetraquark states that have been reported by the LHCb, CMS and ATLAS collaborations in the di- and spectra, we investigate their contr…
