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…

Comments on Baryon Transition Form Factors

Christoph Hanhart, Maxim Mai, Ulf-G. MeiÃner +1

We discuss in rather general terms the properties of space-like baryon transition form factors. In particular, we argue why these are necessarily complex-valued, what can be deduce…

Nature of the $P_{c}$ states from compositeness criteria

Yu-Fei Wang, Chao-Wei Shen, Deborah RÃ¶nchen +3

Based on a coupled-channel approach, we investigate the structures of four $P_{c}$ states through compositeness criteria. Toward a more precise description of the states, we have obt…
