Open Wilson Lines and Generalized Star Product in Noncommutative Scalar Field Theories
Y. Kiem, S. -J. Rey, H. -T. Sato +1
Open Wilson line operators and generalized star product have been studied extensively in noncommutative gauge theories. We show that they also show up in noncommutative scalar fiel…
Noncommutative Sp(2,R) Gauge Theories - A Field Theory Approach to Two-Time Physics
Itzhak Bars, Soo-Jong Rey
Phase-space and its relativistic extension is a natural space for realizing Sp(2,R) symmetry through canonical transformations. On a Dx2 dimensional covariant phase-space, we formu…
Hyper-Kahler Calabi Metrics, L^2 Harmonic Forms, Resolved M2-branes, and AdS_4/CFT_3 Correspondence
M. Cvetic, G. W. Gibbons, H. Lu +1
We obtain a simple explicit expression for the hyper-Kahler Calabi metric on the co-tangent bundle of CP^{n+1}, for all n, in which it is constructed as a metric of cohomogeneity o…
Five-Brane Superpotentials in Heterotic M-Theory
Eduardo Lima, Burt Ovrut, Jaemo Park
The open supermembrane contribution to the non-perturbative superpotential of bulk space five-branes in heterotic M-theory is presented. We explicitly compute the superpotential fo…
Supersymmetric Non-singular Fractional D2-branes and NS-NS 2-branes
M. Cvetic, G. W. Gibbons, H. Lu +1
We obtain regular deformed D2-brane solutions with fractional D2-branes arising as wrapped D4-branes. The space transverse to the D2-brane is a complete Ricci-flat 7-manifold of G_…
All Couplings of Minimal Six-dimensional Supergravity
Fabio Riccioni
We describe the complete coupling of six-dimensional supergravity to tensor, vector and hypermultiplets. The generalized Green-Schwarz mechanism implies that the resulting…
