Parallel session A4: Heavy Flavours 4
- Rafał Maciuła (Institute of Nuclear Physics PAS)
A first non-perturbative and unitary treatment of multichannel systems with anomalous thresholds based on realistic potentials is presented. We consider the isospin one-half example system, with $D \,\pi , D\,\eta, D_s \bar K, D^* \pi , D^*\eta, D^*\bar K$ coupled channels in the $J^P = 1^-$ partial wave, chosen such that various phenomena that come with the opening of an anomalous threshold...
We consider two necessary and sufficient conditions for macrorealism recently appeared in the literature, known as no-signaling-in-time and arrow-of-time conditions, respectively, and study them in the context of flavor transitions, within both the plane wave description and the wave packet approach. We then compare the outcome of the above investigation with the implication of various...
The charmonium state $\eta_{c}$ is the heavy pseudoscalar meson ($J^{PC} = 0^{-+}$) lied under $D\bar D$ threshold. We will review the proton-proton and $e^- A$ reactions, where $\eta_{c}$ can be produced through the two virtual gluons or one virtual photon.
The main ingredient in our light-cone approach is the space-like transition form factor with dependence on two virtualities of the fused...
