Nonabelian Monopoles and the Vortices that Confine Them
Roberto Auzzi, Stefano Bolognesi, Jarah Evslin +1
Nonabelian magnetic monopoles of Goddard-Nuyts-Olive-Weinberg type have recently been shown to appear as the dominant infrared degrees of freedom in a class of softly broken ${\cal…
On orbifold theory and N=2, D=5 gauged supergravity
Yin Lin
We have studied the most general N=2 supergravity in five dimensions in context with the orbifold theory based on . Various ways to treat the supersymmetry with…
Nonabelian Bundle Gerbes, their Differential Geometry and Gauge Theory
Paolo Aschieri, Luigi Cantini, Branislav Jurco
Bundle gerbes are a higher version of line bundles, we present nonabelian bundle gerbes as a higher version of principal bundles. Connection, curving, curvature and gauge transform…
The tetrahedron graph in Liouville theory on the pseudosphere
Pietro Menotti, Erik Tonni
We compute analytically the tetrahedron graph in Liouville theory on the pseudosphere. The result allows to extend the check of the bootstrap formula of Zamolodchikov and Zamolodch…
Nonabelian Superconductors: Vortices and Confinement in SQCD
Roberto Auzzi, Stefano Bolognesi, Jarah Evslin +2
We study nonabelian vortices (flux tubes) in SU(N) gauge theories, which are responsible for the confinement of (nonabelian) magnetic monopoles. In particular a detailed analysis i…
Charge density and electric charge in quantum electrodynamics
G. Morchio, F. Strocchi
The convergence of integrals over charge densities is discussed in relation with the problem of electric charge and (non-local) charged states in Quantum Electrodynamics (QED). Del…
