Dispersive analysis of the process
Bai-Long Hoid, Igor Danilkin, Anna Testa +1
We present a dispersive amplitude analysis of the low-energy system in the radiative decay , using the mass-independent BESIII and intensi…
Simultaneous Dalitz-plot decomposition of the processes in the 4.13-4.36 GeV region using dispersive final-state interactions
Viktoriia Ermolina, Igor Danilkin, Marc Vanderhaeghen
We present a joint analysis of the processes and at center-of-mass energies from 4.13 to 4.36 GeV. The amplitudes are constructed usin…
Sensitivity of MAGIX@MESA to BSM effects via Bethe-Heitler pair production
Aleksandr Pustyntsev, Marc Vanderhaeghen
We explore the sensitivity of the upcoming MAGIX experiment at the MESA facility to light Beyond the Standard Model (BSM) mediators in the few to hundred MeV mass range. Utilizing…
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(…
Coupled-channel Omnès matrix for the -wave isoscalar system and its application to
Igor Danilkin, Oleksandra Deineka, Emilie Passemar +1
In this work, we construct the -wave isoscalar coupled-channel Omnès matrix, formulated to satisfy unitarity, analyticity, and the appropriate asymptotic behavior.…
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…
HadroTOPS: A Monte Carlo Event Generator For Hadron Production In Two-Photon Scattering In Electron Positron Collisions
Max Lellmann, Igor Danilkin, Achim Denig +4
We present a Monte Carlo event generator specifically developed for the study of hadronic two-photon fusion events in two-photon scattering at electron-positron colliders. The code…
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…
Dalitz-plot decomposition for the and processes
Viktoriia Ermolina, Igor Danilkin, Marc Vanderhaeghen
We present an analysis of the and processes employing the recently proposed Dalitz-plot decomposi…
Two-photon exchange corrections in elastic muon-proton scattering
O. Tomalak, M. Vanderhaeghen
We extend the general formalism of two-photon exchange to elastic lepton-nucleon scattering by accounting for all lepton mass terms. We then perform a numerical estimate of the muo…
