Abstract:We present recent results on the spectrum of a confining flux tube that is closed around a spatial torus as a function of its length as well as the spectrum of glueballs. The extraction of the spectra has been realized by simulating four dimensional ππ (π) gauge theories and performing measurements using lattice techniques. Regarding flux-tubes, we have performed calculations for π = 3, 5, 6 and for various values of spin, parity and longitudinal momentum. Long flux-tubes can be thought of as infinitesimal… Show more
