presented. The main attention will be devoted to the analysis of the
data with production of the baryon states in gamma-N collision where
new baryon states had been found. The results of the combined analysis
of these data, measured by the CLAS, CB-ELSA and MAMI collaborations
together with earlier measured data are presented.... -

Evidence for the scalar and the tensor glueball is reported. The evidence stems from an analysis of BESIII data on radiative $J/\psi$ data into $\pi^0\pi^0$, $K_SK_S$, $\eta\eta$, and $\phi\omega$. The coupled-channel analysis is contrained by a large number of further data. The scalar intensity is described by ten scalar isoscalar mesons, covering the range from $f_0(500)$ to $f_0(2330)$....

The Fermilab Muon g-2 Experiment recently reported their first result for the anomalous magnetic moment of the muon that differs from the Standard Model (SM) prediction by 4.2$ standard deviations. The error on the SM prediction, which is comparable in size to the experimental uncertainty, is entirely dominated by the determination of the hadronic contributions, which arise from the...

José R. Peláez (Universidad Complutense de Madrid)08.11.2021, 12:00New Results in Hadron Spectroscopy
In this talk I will review dispersive an analytic methods that have been used used to determine, in a a model-independent way, the existence and properties of light scalar mesons from scattering data. These include dispersive pole determinations of the long debated f_0(500) or sigma, K_0*(700) or kappa and f0(980). We also discuss the combination of dispersive scattering data analyses with...

Проф. Constantia Alexandrou (Univ. of Cyprus)08.11.2021, 12:30Lattice Simulations for Hadron Phenomenology
I will review recent progress in the calculation of the axial and induced pseudoscalar form factors of the proton and neutron within lattice QCD.

In particular, I will emphasise results computed using physical point ensembles. The PCAC and Goldberger-Treiman relations will be discussed as well as the strange axial form factors. -
