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…
Exotics in the system
Eric B. Gregory, Feng-Kun Guo, Christoph Hanhart +2
In this proceedings we consider several states, namely the , , and , which appear to defy description as simple quark-ant…
Confirmation of the existence of an exotic state in the system
Eric B. Gregory, Feng-Kun Guo, Christoph Hanhart +2
In recent years many candidates for states beyond the most simple realization of the quark model were found in various experiments around the world. However, so far no consensus ex…
On the scalar form factor beyond the elastic region
Frederic Noël, Leon von Detten, Christoph Hanhart +2
Pion-kaon () final states, often appearing in heavy-particle decays at the precision frontier, are important for Standard-Model tests, to describe crossed channels with exotic…
