Unquenched Radially Excited $P$ -wave Charmonia

George Rupp

The ground-state positive-parity charmonia $I ¨ _{c 0} (1 P)$ , $I ¨ _{c 1} (1 P)$ , $h_{c} (1 P)$ , and $I ¨ _{c 2} (1 P)$ are generally well described in static (``quenched'') quark models, in which d…

Comment on "Do near-threshold molecular states mix with neighboring $Q ˉ Q$ states?"

George Rupp

I comment on a paper by Christoph Hanhart and Alexey Nefediev, published in Phys. Rev. D 106, 114003 (2022). The authors discuss the interpretation of mesons close to their lowest…

$I ¨ (500)$ resonance pole positions as function of $m_{I ¨} $ : analysis with a unitary coupled-channel model

George Rupp

Resonance pole positions of the $f_{0} (500)$ alias $I ¨ (500)$ meson are computed and plotted as a continuous function of pion mass in the framework of a unitary and analytic coupled-c…

Unitary model analysis of $f_{0} (500)$ pole positions by continuously varying $m_{I ¨} $ : comparison with discrete lattice predictions

George Rupp

Resonance, bound-state, and virtual-state pole positions of the $f_{0} (500)$ scalar meson are computed as a continuous function of pion mass in the framework of a unitarized and anal…
