- Michele Caselle (TO)
Observables in particle physics and specifically in lattice QCD calculations are often extracted from fits. Standard chi^2 tests require a reliable determination of the covariance matrix and its inverse from correlated and auto-correlated data, a challenging task often leading to close-to-singular estimates. These motivate modifications of the definition of chi^2 such as uncorrelated fits. We...
The quark confinement in QCD is well established both experimentally and by the numerical lattice simulations showing a linearly growing quark-antiquark potential. The confinement is further evidenced by the chromoelectric field between a static quark-antiquark pair concentrating in a tube-like structure called a flux tube.
This talk is a review of the recent results establishing the spatial...
I will present recent results for the study of the Random Field Ising
model in various dimensions. Using results of large scale numerical
simulations, I will argue that dimensional reduction is valid at D=5
and that we observe the consequences of supersymmetry.
Next, I will discuss recent analytical results in D=4 which argued
that there should also exist a fixed point with...
