Observables of noncommutative gauge theories
 Adv. Theor. Math. Phys
"... We present a unified treatment of classical solutions of noncommutative gauge theories. We find all solutions of the noncommutative YangMills equations of motion in 2 dimensions; and show that they are labeled by two integers—the rank of the gauge group and the magnetic charge. The magnetic vortex ..."

"... We derive an exact expression for the SeibergWitten map of noncommutative gauge theory. It is found by studying the coupling of the gauge field to the RamondRamond A noncommutative gauge theory can be realized by considering branes in string theory with a strong NSNS twoform field. In [1], it wa ..."

"... We explicitly derive, following a Noetherlike approach, the criteria for preserving Poincaré invariance in noncommutative gauge theories. Using these criteria we discuss the various spacetime symmetries in such theories. It is shown that, interpreted appropriately, Poincaré invariance holds. The an ..."

"... Using path integral method (Fujikawa’s method) we calculate anomalies in noncommutative gauge theories with fermions in the bifundamental and adjoint representations. We find that axial and chiral gauge anomalies coming from nonplanar contributions are derived in the low noncommutative momentum li ..."

Tachyon Condensation in Noncommutative Gauge Theory

"... We show that the decay of the D2D2 system with large worldvolume magnetic fields can be described in noncommutative gauge theory. Tachyon condensation in this system describes the annihilation of D2D2 into D0branes. From the 2 + 1 dimensional point of view, this is the decay of a nonabelian magne ..."

Unstable solitons in noncommutative gauge theory
"... We find a class of exact solutions of noncommutative gauge theories corresponding to unstable nonBPS solitons. In the twodimensional euclidean (or 2+1 dimensional lorentzian) U(1) theory we find localized solutions carrying nonzero magnetic flux. In four euclidean dimensions we find nonBPS soluti ..."

"... We present an explicit classical dyon solution for the noncommutative version of the YangMillsHiggs model (in the PrasadSommerfield limit) with a ϑterm. We show that the relation between classical electric and magnetic charges also holds in noncommutative space. Extending the Noether approach to ..."

 Add to MetaCart
to the case of a noncommutative gauge theory, we analyze the effect of CP violation at the quantum level, induced both by the ϑ term and by noncommutativity and we prove that the Witten effect formula for the dyon charge remains the same as in ordinary space. 1
