The proton magnetic radius: a new puzzle?

Yong-Hui Lin, Hans-Werner Hammer, Ulf-G. Meißner

We comment on the puzzling status of the proton magnetic radius determinations.

Pion axioproduction revisited

Cheng-Cheng Li, Tao-Ran Hu, Feng-Kun Guo +1

In this work, we extend the analysis of the pion axioproduction, $a N \to π N$ , to include the impact of the Roper resonance $N^{*} (1440)$ together the previously studied $Δ (1232)$ r…

Method for measuring the charge radii of charged hyperons from the time-like region

Yong-Hui Lin, Feng-Kun Guo, Ulf-G. Meißner

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…

New insights into the nature of the $Λ (1380)$ and $Λ (1405)$ resonances away from the SU(3) limit

Feng-Kun Guo, Yuki Kamiya, Maxim Mai +1

Starting from the SU(3) limit, we consider the nature of the dynamically generated resonances $Λ (1380)$ , $Λ (1405)$ and $Λ (1680)$ as the pion and kaon masses are tuned to their phys…

Electromagnetic and gravitational local spatial densities for spin-1 systems

J. Yu. Panteleeva, E. Epelbaum, J. Gegelia +1

The matrix elements of the electromagnetic current and the energy-momentum tensor for sharply localized states of spin-1 systems are considered. Their interpretation as local spati…

Unified tetraquark equations

A. N. Kvinikhidze, B. Blankleider

We derive covariant equations describing the tetraquark in terms of an admixture of two-body states $D D ˉ$ (diquark-antidiquark), $M M$ (meson-meson), and three-body-like states…

Determination of diffractive PDFs from global QCD analysis of inclusive diffractive DIS and dijet cross-section measurements at HERA

Maral Salajegheh, Hamzeh Khanpour, Ulf-G. Meißner +2

We present an updated set of {\tt SKMHS} diffractive parton distribution functions (PDFs). In addition to the diffractive deep-inelastic scattering (diffractive DIS) data sets, the…

Revealing the nature of hidden charm pentaquarks with machine learning

Zhenyu Zhang, Jiahao Liu, Jifeng Hu +2

We study the nature of the hidden charm pentaquarks, i.e. the $P_{c} (4312)$ , $P_{c} (4440)$ and $P_{c} (4457)$ , with a neural network approach in pionless effective field theory. In this f…
