DESCRIPTION:Speakers: 文正 侯 (south china normal university)\nUsing $N
 _f = 2+1$ clover fermions across six gauge ensembles generated by the CLQC
 D collaboration\, this work performs simultaneous chiral and continuum ext
 rapolations to determine the electromagnetic properties of charmed mesons\
 , providing the first lattice QCD calculations for the magnetic moments an
 d radii of $D^{\\ast+}$ and $D_s^\\ast$\, and filling the gap for the $D_s
 ^*$ charge radius. The preliminary numerical results yield the charge radi
 i squared as $(r_c)_D^2=0.208(26)~\\text{fm}^2$\, $(r_c)_{D^{\\ast+}}^2=0.
 258(25)~\\text{fm}^2$\, $(r_c)_{D_s}^2=0.083(17)~\\text{fm}^2$\, and $(r_c
 )_{D^{\\ast}_s}^2=0.101(15)~\\text{fm}^2$\; the magnetic dipole moments as
  $(G_M)_{D^{\\ast+}}=2.21(17)$ and $(G_M)_{D_s^{\\ast+}}=2.19(12)$\; and t
 he magnetic radii squared as $(r_m)_{D^{\\ast+}}^2=103(84)~\\text{fm}^2$ a
 nd $(r_m)_{D_s^{\\ast}}^2=0.088(54)~\\text{fm}^2$.\n\nhttps://indico.itp.a
