The nature of the $X(3915)/X(3930)$ resonances from a coupled-channels approach
- Physics
- 2017
The positive parity $\chi_{cJ}(2P)$ charmonium states are expected to lie around the 3.9 GeV/$c^2$ energy region, according to the predictions of quark models. However, a plethora of states with…

The LHCb collaboration, using its full data set from runs 1 and 2, announced in 2019 a surprising update of the hidden-charm pentaquark states Pc(4380)+ and Pc(4450)+, observed in 2015. A new state,…
Light-meson masses in an unquenched quark model
- Physics

Identifying the X(3915) with the X (3930) and abandoning the helicity-2 dominance for this tensor state are helpful for the further understandings of the properties of this state and also of the mysterious "XYZ" charmoniumlike resonances.
