Charm sea effects on charmonium decay constants and heavy meson masses
Salvatore Cali, Kevin Eckert, Jochen Heitger +2
We estimate the effects on the decay constants of charmonium and on heavy meson masses due to the charm quark in the sea. Our goal is to understand whether for these quantities $N_…

How much do charm sea quarks affect the charmonium spectrum?
Salvatore Cali, Francesco Knechtli, Tomasz Korzec
The properties of charmonium states are or will be intensively studied by the B-factories Belle II and BESIII, the LHCb and PANDA experiments and at a future Super-c-tau Factory. P…

Comparison between models of QCD with and without dynamical charm quarks
Salvatore Cali, Francesco Knechtli, Tomasz Korzec
We investigate the influence of dynamical charm quarks on observables that depend explicitly on the charm quark fields, like the pseudo-scalar and vector masses and $m_{J…
