DESCRIPTION:Speakers: Marc Klegrewe (Bielefeld University)\nWe present res
ults for lattice QCD in the limit of infinite gauge coupling on a discrete
spatial but continuous Euclidean time lattice. A worm type Monte Carlo al
gorithm is applied in order to sample two-point functions which gives acc
ess to the measurement of mesonic temporal correlators. The continuous tim
e limit\, based on sending NĪââ and the bare anistotropy to infinity
while fixing the temperature in a non-perturbative setup\, has various adv
antages: the algorithm is sign problem free\, fast\, and accumulates high
statistics for correlation functions. Even though the measurement of tempo
ral correlators requires the introduction of a binning in time direction\,
this discretization can be chosen to be by orders finer compared to discr
ete computations. For different spatial volumes and binnings\, temporal co
rrelators are measured at zero spatial momentum for a variety of mesonic o
perators. They are fitted to extract the pole masses and corresponding par
ticles as a function of the temperature. We conclude discussing the possib
ility to extract transport coefficients from these correlators.\n\nhttps:/
