"Colour flux tubes of exotic hadrons, computed in Lattice QCD"

The colour fields created by the static glueball, hybrid, tetraquark
and pentaquark systemss are computed in quenched SU(3) lattice QCD,
with gauge invariant lattice operators . We generate our quenched
configurations with GPUs, and detail the respective benchmanrks in
different SU(N) groups. While at smaller distances the coulomb
potential is expected to dominate, at larger distances it is expected
that fundamental flux tubes, similar to the flux-tube between a quark
and an antiquark, emerge and confine the quarks. We compute the square
of the colour fields utilizing plaquettes, and locate the static
sources with generalized Wilson loops and with APE smearing.
