Title:
SU(N) gauge theories in 3+1 dimensions: glueball spectra, running couplings, $k$-strings, topology.
Speaker:
Abstract:
We use lattice simulations to calculate some properties of SU(N) gauge theories in the continuum limit. We do so from N=2 to N=12, enabling an extrapolation to N=infinity. Our main aim is to calculate the lightest glueball masses for all JPC quantum numbers. As a byproduct, we calculate some string tensions, the running of the coupling with an estimate of the Lambda parameter, and some properties of the topological fluctuations of the gauge fields.
