We investigate the feasibility of measuring the proton charge radius through dimuon photoproduction off a proton target. Our findings indicate that the Bethe-Heitler mechanism, which dominates at small momentum transfers, allows for an extraction of

We propose a novel method for measuring the charge radii of charged stable hadrons, with which the first measurement of the charge radii of the Σ+ and the Ξ− is foreseen. The method explores the facts that the Dalitz decay ψ(2S)→YY¯e+e− con

Abstract Starting from an effective Lagrangian with heavy quark spin symmetry embedded, the coupled-channel dynamics of the doubly charmed systems $$D^{(*)} \Sigma _c^{(*)}$$ D ( ∗ ) Σ c ( ∗ ) is investigated. The potential underlying our invest

Abstract The electromagnetic form factors of the $$\Lambda $$ Λ hyperon in the time-like region are determined precisely through a dispersion-theoretical analysis of the world data for the cross section of the annihilation process $$e^+e^-\rightarro

We present a high-precision calculation of the recoil–finite-size correction to the hyperfine splitting (HFS) in muonic and electronic hydrogen based on nucleon electromagnetic form factors obtained from dispersion theory. This will help guide the

We predict the differential cross sections for e−p and e+p elastic scattering in the PRad-II energy region. The prediction is based on form factors obtained in our previous high-precision analysis of space- and time-like data from dispersion theory

Using dispersion theory with an improved description of the two-pion continuum based on the precise Roy-Steiner analysis of pion-nucleon scattering, we analyze recent data from electron-proton scattering. This allows for a high-precision determinatio

The internal structure of the charm-strange mesons $D_{s0}^*(2317)$ and $D_{s1}(2460)$ are subject of intensive studies. Their widths are small because they decay dominantly through isospin-breaking hadronic channels $D_{s0}^*(2317)^+\to D_s^+\pi^0$
