DESCRIPTION:Speakers: 清扬 刘 (ihep)\nThe charm quark density-density c
 orrelation is calculated for 1S and 1P conventional charmonia and $J^{PC}=
 1^{−+}\,0^{+−}$ charmoniumlike states from lattice QCD and are interpr
 eted as spatial wave functions of these states with some approximations. T
 he angular distributions of $c\\bar{c}$ in conventional charmonia are foun
 d to be in accordance with the expectation of two-body systems\, while tha
 t of the $1^{−+}$ state exhibits an S-wave feature. However\, the $c\\ba
 r{c}$ radial distributions turn out to be strikingly different from the no
 n-relativistic quark model and can be understood by the Dirac theory of tw
 o-body bound states. These results provide the first gauge invariant and m
 odel-independent three-dimensional portraits of charmonium(like) states.\n
