DESCRIPTION:Speakers: Dr. KOPONEN\, Jonna (University of Mainz)\nThe preci
 sion of lattice QCD calculations has been steadily improving for some time
  and is now approaching\, or has surpassed\, the 1% level for multiple qua
 ntities. At this level QED effects\, i.e. the fact that quarks carry elect
 ric as well as color charge\, come into play. In this talk we will present
  results from the first lattice QCD+QED computations of the properties of 
 ground-state charmonium and bottomonium mesons.\n\nhttps://indico.nucleare

DESCRIPTION:Speakers: PEDLAR\, Todd (Luther)\nWe report the first measurem
 ent of exclusive cross sections for $e^+e^-\\to B\\bar{B}$\, $B\\bar{B}^\\
 star$ and $B^\\star\\bar{B}^\\star$ in an energy range 10.63-11.02 GeV. B 
 mesons are reconstructed in a number of hadronic final states\, and the th
 ree channels are separated with the beam-energy constrained mass. Results 
 on $\\Upsilon(5S)\\to \\Upsilon(1S\,2S)\\eta$ and $\\Upsilon(1S)\\eta^\\pr
 ime$ branching fractions are also presented. In addition\, we search for t
 he $\\chi_{bJ}(nP)\\to\\Upsilon(1S)\\omega$ decay.\n\nhttps://indico.nucle

SUMMARY:Bottomonium results and prospects at Belle II

DESCRIPTION:Speakers: FULSOM\, Bryan (Pacific Northwest National Laborator
 y)\nBottomonium is the bound state of a bottom and anti-bottom quark. Stud
 ies of this system provide insights into our understanding of QCD. The Bel
 le II experiment at the SuperKEKB $e^+ e^-$ collider is an upgrade of the 
 B factory facility at KEK in Tsukuba\, Japan. We present some recent resul
 ts and describe the unique discovery potential for bottomonium physics and
  related exotic QCD states that this opportunity will provide.\n\nhttps://

DESCRIPTION:Speakers: Dr. GHALENOVI\, Zahra (Kosar University of Bojnord)\
 nUsing a variational approach we calculate the mass spectra of the bottom 
 mesons in the framework of the phenomenological quark anti-quark potential
 .  Decay constant and Leptonic decay widths of the bottom mesons are also 
 calculated. The obtained results are compared with the available experimen
 tal data and other theoretical predictions.\n\nhttps://indico.nucleares.un

SUMMARY:Radiative transitions of charmonium states in the  Covariant Quark

DESCRIPTION:Speakers: Dr. GANBOLD\, Gurjav (Joint Institute for Nuclear Re
 search\, Dubna\, Russia)\nWe have studied one-photon radiative transitions
  of the charmonium $S$- and $P$-wave states within an analytic confinement
  model.  Along two fixed basic model parameters (the c-quark mass and the 
 global cutoff $\\lambda$) we introduced only one adjustable parameter comm
 on for charmonium states $\\eta_c$\, $J/\\psi$\, $\\chi_{c0}$\, $\\chi_{c1
 }$\,  $h_c$ and $\\chi_{c2}$ to describe the quark distribution inside the
  hadron. Our estimates are in good agreement with the latest data.\n\nhttp
