Hadron Physics Opportunities at FAIR

J. G. Messchendorp, F. Nerling, P. Achenbach +103

This White Paper outlines a coordinated, decade-spanning programme of hadron and QCD studies anchored at the GSI/FAIR accelerator complex. Profiting from intense deuteron, proton a…

What can we learn from the radiative decays of the $D_{s 1} (2460)$ meson?

Hai-Long Fu, Feng-Kun Guo, Christoph Hanhart +1

We study the radiative decays $D_{s 1} (2460) \to γ D_{s 0}^{*} (2317)$ and $D_{s 1} (2460) \to γ D^{0} K^{+} / γ D^{+} K^{0}$ and argue that their simultaneous experimental measurement, or at least a con…

Dispersive analysis of the $J / ψ \to π^{0} γ^{*}$ transition form factor with $ρ$ - $ω$ mixing effects

Xiong-Hui Cao, Feng-Kun Guo, Christoph Hanhart +1

Motivated by the discrepancies noted recently between the theoretical predictions of the electromagnetic $J / ψ \to π^{0} γ^{*}$ transition form factor and the BESIII data, we reanalyze t…

Discovering the $D_{0}^{*} (2100)$ in $B$ semileptonic decays

M. -L. Du, F. -K. Guo, C. Hanhart +3

The mass and width of the lightest scalar open-charm state listed in the Review of Particle Physics, the $D_{0}^{*} (2300)$ , are in puzzling tension with predictions from unitarized…

Single- and double-heavy Hadronic Molecules

C. Hanhart

In this presentation the notion of hadronic molecules is reviewed and it is argued that some of the enigmatic single and double heavy mesons, namely the lowest lying positive parit…

Understanding large localized CP violation in $B^{\pm} \to K^{\pm} π^{+} π^{-}$ using dispersive methods

L. A. Heuser, A. Reyes-Torrecilla, C. Hanhart +4

We utilize the universality of pion-pion ( $π π$ ) final-state interactions at small invariant masses to understand the enhanced localized CP violation in $B^{\pm} \to K^{\pm} π^{+} π^{-}$ , usin…
