DESCRIPTION:Speakers: Svjetlana Fajfer (Department of Theoretical Physics\
 , Jožef Stefan Institute)\nUnderstanding  charm hadrons structures and d
 ynamics motivates many studies\nwithin QCD. In particular Lattice QCD can 
 provide us with precise\ncalculation of the hadronic inputs required in 
  the   extraction of the CKM matrix elements as well as  leads to under
 standing of the exotic QCD structure as tertraquarks. \n\nIn the electrow
 eak sector  B meson anomalies and muon anomalous magnetic\nmoments initia
 ted many studies of physics beyond the Standard Model. The\nquestion is wh
 ether  charm sector can be affected by the same New Physics.\n\nIntensive
  studies of Dark Matter stimulated a number of studies aimed to\nconstrain
  or observe its presence in charm meson decays with the invisible\nparticl
 es in the final state.\n\nhttps://indico.inp.nsk.su/event/15/contributions

 nIt is shown that the $e^+e^-\\to Z\\to\\chi_{c1}/\\chi_{b1}$ and $e^+e^-\
 \to\\gamma^{\\ast}\\gamma^{\\ast}\\to\\chi_{c1}/\\chi_{b1}$ contributions 
 do not interfere in the total cross sections. That is\, the creation of lo
 ngitudinally polarized electron-positron\nbeams allows to study separately
  the $e^+e^-\\to Z\\to\\chi_{c1}/\\chi_{b1}$ and\n$e^+e^-\\to\\gamma^{\\as
 t}\\gamma^{\\ast}\\to\\chi_{c1}/\\chi_{b1}$.\n\nIn the discussed energy re
 gion the weak interaction grows with\nenergy increase $\\propto G_FE^2$\, 
 where $G_F=10^{-5}m_p^{-2}$ is\nthe Fermi constant. $G_FE^2=1.4\\times 10^
 {-4}$ for $\\chi_{c1}(1P)$\nand $G_FE^2=1.7\\times 10^{-4}$ for $\\chi_{c1
 }(3872)$. That is\,\n$G_FE^2\\sim \\alpha^2$ in the BES III energy region.
 \n$G_FE^2=1.1\\times 10^{-3}$ for $\\chi_{b1}(1P)$ and\n$G_FE^2=1.2\\times
  10^{-3}$ for $\\chi_{b1}(2P)$. That is\,\n$G_FE^2\\gg\\alpha^2$ in the Be
 lle II energy region.\n\nThe  BESS III luminosity $10^{33} cm^{-2}s^{-1}$ 
 gives possibilities to register near hundred of events $e^+e^-\\to Z\\to\\
 chi_{c1}(1P)$ per day and near thirty of them in the well-known channel $\
 \chi_{c1}(1P)\\to\\gamma\\psi(1S)$. If $\\chi_{c1}(3872)=\\chi_{c1}(2P)$\,
  then also near hundred of events $e^+e^-\\to Z\\to\\chi_{c1}(3872)$ per d
 ay may be registered and  several of them in the channel $\\chi_{c1}(3872)
 \\to\\gamma\\psi(2S)$\, several tens of them in the channel $\\chi_{c1}(38
 72)\\to D^0\\bar D^{0\\ast}+c.c$.\n\nThe huge Belle II luminosity $8\\time
 s 10^{35} cm^{-2}s^{-1}$ gives possibilities to register near hundred thou
 sand of events each $e^+e^-\\to Z\\to\\chi_{b1}(1P)$ and\n$e^+e^-\\to Z\\t
 o\\chi_{b1}(1P)$ per day  and several tens of thousands of them in the wel

 th the KEDR detector at the VEPP-4M e+e- collider. \nLeptonic width of J/
 ψ meson and its composition to hadronic and electronic branching fraction
 s \nhave been measured directly with the processes  e+e- →hadrons and e+
 e- →e+e-  at J/ψ\nresonance energy range. The obtained accuracy is less
  than 2%. \nThe product of the electronic width of the ψ(2S) meson and th
 e branching fraction of its decay to the muon pair has been measured in th
 e\n e+e−→ψ(2S)→μ+μ− process  with the world best accuracy about
  3%.\n Leptonic width of ψ(2S) meson was calculated\, using the  previous
  KEDR measurements\nwith the lepton universality assumption and without it

 re enhanced in the Belle II physics program. In the sector of charmonium a
 nd spectroscopy\, Belle II will\ninvestigate several physics processes: IS
 R physics for the vector states and bottomonium search are  some examples 
 where the contribution of the this experiment will help\nin better underst
 anding QCD\, for which several open questions still remain. First simulati
 ons and data analyses will be shown\, with the first available dataset (20

DESCRIPTION:Speakers: Stephen Lars OLSEN (University of Chinese Academy of
  Sciences)\nThe list of XYZ mesons\, which was initiated 16 years ago\, co
 ntinues to expand.\nAlthough these states have a number of common properti
 es\, including: large\nbranching fractions to hidden-quarkonium states (in
  spite of kinematically\naccessible open-flavor\, fall-apart decay channel
 s)\; relatively narrow widths\; and\npreferences for $J^{P(C)} =1^{+(+)}$ 
 quantum numbers\, no single theoretical model can\nprovide a comprehensive
  description for them. Since the models that have been\nproposed: molecule
 s\, tetraquarks\, QCD-hybrids\, hadro-quarkonium\, etc.\, can\, at\nbest\,
  provide adequate descriptions for only a small subset of the observations
 \, a\nconcise exposition of what are they? is a Sisyphean task that I have
  given up on.\nInstead\, I restrict myself to the easier question: what ar
 en’t they?\n\nhttps://indico.inp.nsk.su/event/15/contributions/642/

DESCRIPTION:Speakers: Alexey Nefediev (Lebedev Physical Institute)\nThe mo
 st recent experimental data for the decays of the vector bottomonium Upsil
 on(10860) proceeding through the formation of the states Zb(10610) and Zb(
 10650) are analysed simultaneously using solutions of the Lippmann-Schwing
 er equations which respect constraints from unitarity and analyticity. The
  interaction potential in the open-bottom channels B(*)-anti-B* contains s
 hort-range interactions as well as the one-pion exchange\; both types of t
 he interaction are taken into account fully nonperturbatively. This way\, 
 all parameters of the interaction are fixed directly from the data and the
  pole positions for the Zb's are determined as a prediction. In particular
 \, both Zb states are found to be described by poles located on the unphys
 ical Riemann sheets in the vicinity of the corresponding thresholds: the Z
 b(10610) is associated with a virtual state residing just below the B-anti
 -B* threshold while the Zb(10650) state is most likely located just above 
 the B*-anti-B* threshold. The heavy quark spin symmetry is employed to pre
 dict\, in a parameter-free way\, the pole positions and the line shapes in
  the elastic and inelastic channels for the Zbs' spin partner states W_bJ 
 with the quantum numbers J++ (J=0\,1\,2). Such spin partners can be produc
 ed in radiative decays of the Upsilon(10860) state and\, if they exist\, a
 re expected to be detected in the Belle-II experiment.\n\nhttps://indico.i
