DESCRIPTION:Speakers: Akihiro Shibata (KEK)\nWe investigate the type of du
al superconductivity responsible for quark confinement. For this purpose\
, we first obtain the static vortex solution of U(N) gauge-scalar models\,
which reduces to the Abrikosov-Nielsen-Olesen vortex in the U(1) case\, b
y numerically solving the field equations of the gauge-scalar models in th
e whole range of space without restricting to the long-distance region. Th
en we use the resulting magnetic field of the vortex to fit the gauge-inva
riant chromoelectric field connecting a pair of quark and antiquark which
was obtained by our numerical simulations for SU(2) and SU(3) Yang-Mills t
heories on a lattice. This result improves the accuracy of the fitted valu
e for the Ginzburg-Landau parameter to reconfirm the type I dual supercond
uctivity for quark confinement. Moreover\, we calculate the Maxwell stress
tensor to obtain the distribution of the force around the flux tube. This
suggests the attractive force acting perpendicular to the chromoelectric
flux tube\, in agreement with the type I dual superconductivity.\n\nhttps:
