Vector charmonium(-like) states in the energy range of 4.1-4.6 GeV
Xiang-Kun Dong, Vadim Baru, Leon von Detten +5
The spectrum of vector charmonium(-like) states in the 4.1\dash4.6~GeV energy region exhibits a long-standing tension between inclusive and exclusive measurements. While the inclus…

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…

How many vector charmonium(-like) states sit in the energy range from to GeV?
Leon von Detten, Vadim Baru, Christoph Hanhart +3
In recent years many vector charmonium(-like) states were reported by different electron-positron collider experiments above GeV. However, so far, there not only exists sizab…
