The structure of the lightest positive-parity charmed mesons from LQCD
Eric B. Gregory, Feng-Kun Guo, Christoph Hanhart +2
The nature of low-lying scalar and axial-vector charmed mesons has long been debated, specifically whether they are best explained as hadronic molecules or compact tetraquark syste…

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…

Exclusion of a diquark-antidiquark structure for the lightest positive-parity charmed mesons
Eric B. Gregory, Feng-Kun Guo, Christoph Hanhart +2
The nature of low-lying scalar and axial-vector charmed mesons has been debated for decades, with hadronic molecular and compact tetraquark models being prominent candidates. These…
