DESCRIPTION:Speakers: WAGNER\, Mathias (Bonn)\nwe have shown that the rece
 ntly discovered resonance-like signal $a_1(1420)$ can be fully explained b
 y the decay of the ground-state $a_1(1260)$ into $K^*\\bar{K}$ and subsequ
 ent rescattering through a triangle singularity into the observed final st
 ate $f_0(980)\\pi$ without the need of a new genuine $a_1$ resonance. The 
 effect of the triangle singularity\, which is expected to be present\, is 
 sufficient to explain the observation.\n\nhttps://indico.nucleares.unam.mx

DESCRIPTION:Speakers: WHARTON\, Andrew Mark (Lancaster)\nRecent results fr
 om the ATLAS experiment on searches and measurements of exotic heavy hadro
 ns will be presented. Studies of the pentaquarks with hidden charm in the 
 Lambda_b decays in proton-proton collisions at 7 - 8 TeV will be discussed
 . New results on the heavy tetraquarks in the Run 2 data at 13 TeV will al
 so be reported.\n\nhttps://indico.nucleares.unam.mx/event/1541/session/61/

SUMMARY:Branching ratio and decay widths of the main\, hidden and open cha

DESCRIPTION:Speakers: Mr. MISTRY\, Rahul (V S Patel College of Arts and Sc
 ience Bilimora)\nThe fully charmed and bottom tetraquark is studied in the
  framework of non-relativistic quark model. Using mass spectra and wavefun
 ctions\, branching ratio and decay widths of the main\, hidden and open ch
 arm (and bottom) channels of tetraquark are calculated and also consistent
  with the available experimental observations.\n\nhttps://indico.nucleares

SUMMARY:$P_c$ Resonances in the Compact Pentaquark Picture

DESCRIPTION:Speakers: Mr. RUANGYOO\, Wiriya (Suranaree University of Techn
 ology)\nThe study of $P_c$ resonances in the compact pentaquark picture is
  performed in quark model and group theory. It is found that there are tot
 ally 17 possible compact pentaquark states\, where the hidden heavy pentaq
 uark states may take the color singlet-singlet and color octet-octet confi
 gurations. The partial widths of strong decay indicate that $P_c(4440)$ ma
 y not be a compact pentaquark state while $P_c(4312)$ and $P_c(4457)$ coul
 d be the spin-$\\frac{1}{2}$ and spin-$\\frac{3}{2}$\, respectively.\n\nht
