“…Other reactions and decays to study them are suggested from the theoretical perspective [33,[220][221][222][223]. A search in the electroproduction of the nonstrange channels is viable when more measurements will become available [200,201,224]. Whether they are accessible at EicC and US-EIC needs careful investigation by means of available tools.…”

Accessing a full image of the inner content of hadrons represents a central endeavour of modern particle physics, with the main scientific motivation to investigate the strong interaction binding the visible matter. On the one hand, the structure of known exotic candidates is a fundamental open issue addressed widely by scientists. On the other hand, looking for new states of exotic nature is a central component for theoretical and experimental efforts from electron-positron machine and electron accelerator with fixed target to heavy ion and electron-ion colliders. In this article we present a succinct short overview of the attempt to search for exotic narrow N * and Z states containing light quarks only or also charm, and its connotation for bottom regions (the latter two are also known as P c (Z c ) and P b (Z b ) states, respectively in the literature). We address the effort of searching for exotic narrow N * and Z states in light quark sector. We focus on recent progress in searching for signal of P c and Z c states photoproduction and its implication into the P b and Z b photoproduction and their decay properties. We also discuss future perspectives for the field in electron-ion colliders, a good place to disentangle the nature of some of these states and investigate some other enlightening topics including QCD trace anomaly and quarkonium-nucleon scattering length.

Jülich-Bonn-Washington model for pion electroproduction multipoles

et al. 2021

View full text Add to dashboard Cite

Exclusive electroproduction reactions provide an access to the structure of excited baryons. To extract electroproduction multipoles encoding this information, the Jülich-Bonn-Washington (JBW) analysis framework is extended to the analysis of differential cross sections in KΛ electroproduction. This update enlarges the scope of previous coupled-channel analyses of pions and eta mesons, with photoproduction reactions as boundary condition in all analyzed electroproduction reactions. Polarization observables are predicted and compared to recent CLAS data. The comparison shows the relevance of these data to pin down baryon properties.
