Mass spectrum of the 3d SU(2) Higgs model and the symmetric electroweak phase
Nuclear Physics B - Proceedings Supplements 53:1-3 (1997) 626-628
Abstract:
We present results for the masses of the low-lying states with quantum numbers 0++, 2++ and 1-- as well as Polyakov line correlations in the Higgs and confinement regions of the 3d SU(2) Higgs model. In the confinement phase we find a dense spectrum of bound states approximately split into two disjoint sectors. One consists of W-balls nearly identical to the glueball spectrum of the pure gauge theory, the other of bound states of scalars.Monopole spectra in non-Abelian gauge theories
Nuclear Physics B - Proceedings Supplements 53:1-3 (1997) 497-499
Abstract:
We study the continuum limit of the length spectrum of magnetic monopole structures found after various Abelian projections of pure gauge SU(2), including the maximally Abelian gauge. We comment on Gribov copies, and measurements of the string tension.SU(Nc ) gauge theories for all Nc
Nuclear Physics B - Proceedings Supplements 53:1-3 (1997) 715-718
Abstract:
We show that SU (Nc) gauge theories in 2+1 dimensions are close to Nc = ∞ for Nc ≥ 2. The dimensionful coupling, g2, is proportional to 1/Nc, at large Nc, confirming the usual diagram-based expectation. Preliminary calculations in 3+1 dimensions indicate that the same is true there.COMMENTS ON THE HIGH Q**2 HERA ANOMALY
