`t Hooft model on the Lattice
/ García Pérez, Margarita (Madrid, IFT) ; González-Arroyo, Antonio (Madrid, Autonoma U. ; Madrid, IFT) ; Keegan, Liam (CERN) ; Okawa, Masanori (Hiroshima U.)
Lattice results are presented for the meson spectrum of 1+1 dimensional gauge theory at large $N$, using the Twisted Eguchi-Kawai model. Comparison is made to the results obtained by `t Hooft in the light cone gauge..

The $SU(\infty)$ twisted gradient flow running coupling
/ García Pérez, Margarita (Madrid, IFT) ; González-Arroyo, Antonio (Madrid, IFT ; Madrid, Autonoma U.) ; Keegan, Liam (CERN) ; Okawa, Masanori (Hiroshima U.)
We measure the running of the $SU(\infty)$ 't Hooft coupling by performing a step scaling analysis of the Twisted Eguchi-Kawai (TEK) model, the SU($N$) gauge theory on a single site lattice with twisted boundary conditions. The computation relies on the conjecture that finite volume effects for SU(N) gauge theories defined on a 4-dimensional twisted torus are controlled by an effective size parameter $\tilde l = l \sqrt{N}$, with $l$ the torus period.

/QCD-TARO Collaboration
The properties of hadron screening masses around the deconfinement phase transition at finite baryonic density can be studied by evaluating the Taylor coefficients with respect to the iso-scalar and iso-vector chemical potentials. We simulate 2-flavour lattice QCD with staggered fermions on a 12*12*24*6 lattice with ma = 0.05 and 0.10 and report investigations of nucleon, pseudo-scalar and vector mesons. [...]

Cooling, Physical Scales and the Vacuum Structure of Y-M Theories
/ Garcia Perez, Margarita (Madrid, Autonoma U.) ; Philipsen, Owe (CERN) ; Stamatescu, Ion-Olimpiu (Heidelberg, FEST)
We present a cooling method controlled by a physical cooling radius that defines a scale below which fluctuations are smoothed out while leaving physics unchanged at all larger scales. This method can be generally used as a gauge invariant low pass filter to extract the physics from noisy MC configurations. [...]

Topological Properties of the QCD Vacuum at $T$=0 and $T \sim T_{c}$
/ de Forcrand, Philippe (Zurich, ETH) ; Garcia Perez, Margarita (CERN) ; Hetrick, James E. (U. Pacific, Stockton) ; Stamatescu, Ion-Olimpiu (Heidelberg, FEST ; Heidelberg U.)
We study on the lattice the topology of SU(2) and SU(3) Yang-Mills theories at zero temperature and of QCD at temperatures around the phase transition. To smooth out dislocations and the UV noise we cool the configurations with an action which has scale invariant instanton solutions for instanton size above about 2.3 lattice spacings. [...]
