DESCRIPTION:Speakers: ALBALADEJO\, Miguel (JLab/IFIC)\nIn this talk\, the 
 status of the lowest-lying positive-parity open-charm mesons will be addre
 ssed. In particular\, we will discuss the pole structure associated with t
 he D*0(2400) (in PDG nomenclature) resonance. By analyzing experimental da
 ta and LQCD simulation results within a specific theoretical framework\, w
 e conclude the presence of two different poles (instead of a single one) f
 or the D*0(2400) structure.\n\nhttps://indico.nucleares.unam.mx/event/1541

SUMMARY:The lightest $D_0^*$ resonance from QCD

DESCRIPTION:Speakers: Mr. LANG\, Nicolas (Trinity College Dublin)\nFor the
  first time\, we map out the energy dependence of the elastic Isospin-1/2 
 D$\\pi$ scattering amplitude and find a complex $D_0^*$ resonance pole\, u
 sing Lattice QCD with a pion mass $m_{\\pi}=239$ MeV. The resonance\, whic
 h is lighter than the $D_{s0}^⋆$ found on the same lattice\, is strongly
  coupled to the S-wave $D\\pi$ channel. We find that both $q\\bar{q}$- and
  $D\\pi$-like constructions are necessary to interpolate the corresponding
  spectrum from the vacuum.\n\nBased on arXiv:2102.04973\n\nhttps://indico.

SUMMARY:Exotic and excited open charm spectroscopy in B decays at LHCb

DESCRIPTION:Speakers: Mr. REIS\, Alberto Correa (Centro Brasileiro de Pesq
 uisas Fisicas)\nThe latest spectroscopy measurements of open charm hadrons
  produced in beauty decays at LHCb are reported. These include the observa
 tion of new "exotic" hadron candidates that don't fit into the conventiona
 l picture of three-quark baryons and quark-antiquark mesons. Also observed
  are new excited charm states. These results provide tests of the predicti
 ons from lattice QCD and HQET. Excited charm studies are also invaluable t
 o understanding backgrounds in lepton-flavour universality measurements.\n

DESCRIPTION:Speakers: Dr. MARTIN CONTRERAS\, Miguel Angel (Universidad de 
 Valparaiso)\nMotivated by the fact that mesonic constituent mass $m_q$ bre
 aks linearity in Regge trajectories\, we discuss how to implement nonlinea
 r behavior holographically by deforming the quadratic dilaton into a non-q
 uadratic one. This deformation adds an extra parameter into the model\, wh
 ich measures the $m_q$ effect\, accounting for nonlinearity in the traject
 ory. We applied this model to the description of the isovector multiplet s
 pectrum\, vector heavy-light mesons\, and vector non $q\\bar{q}$ states.\n
