11. Scalar meson $f_0(500)$ from the analysis of pion scalar form factor and the correct S-wave isoscalar $\pi\pi$ phase shift data

Prof. Stanislav Dubnicka (Institute of Physics, Slovak Academy of Sciences, Bratislava, Slovak Republic)

In the recently elaborated fully solvable mathematical problem to be concerned of a finding of an explicit form of the pion scalar form factor the inaccurate experimental information in the elastic region on the S-wave isoscalar $\pi\pi$ phase shift, is replaced by the data with theoretical errors to be generated by the Garcia-Martin-Kaminski-Pela'ez-Yndurain Roy-like equations and as a...

21. The $\pi\pi$ scattering amplitude and the $\sigma$ meson

Petr Bydzovsky (Nuclear Physics Institute AS CR)

We constructed the multichannel $\pi\pi$ amplitudes in the S- and P-waves which satisfactorily describe the $\pi\pi$ scattering data [1]. In the construction we have utilized the uniformizing variable and formulas for analytical continuation of the S-matrix elements to all sheets of the Riemann surface but we did not fully include the constraint on the crossing symmetry which is...

12. Recents results on charmonium-like states at BESIII

Myroslav Kavatsyuk (KVI-CART, University of Groningen)

Despite the successes of the Standard Model, the QCD-based nature of the strong interaction is insufficiently understood. Charmonium spectroscopy is an ideal tool to provide insight into the non-perturbative dynamics of the strong force. It provides rigorous guidelines to various theoretical approaches, thereby, gaining insight into quark confinement and the formation of hadronic matter. The...

14. Is the spacetime Euclidean inside the hadrons?

Vladimir Sauli (Nuclear Institute Rez near Prague)

Solution of Schwinger-Dyson and Bethe-Salpeter Equations for excited and ground state pions will be presented. The quark gap equation has been solved directly in our Minkowski space-time and the solution, according to confinement, does not allow a free quark propagation. The Minkowski space solution for confining QCD as will be shown, is not only numerically accessible, but also ...
