IIB seven–branes revisited
We re–investigate the construction of half–supersymmetric seven–brane solutions of IIB supergavity. In contrast to previous approaches we allow the occurrence of objects with monodromy Tr Λ 6= 2. We obtain non-trivial information from the requirement of a globally well–defined Killing spinor and by including SL(2,Z)–invariant source terms.
متن کاملIIB-Branes and New Spacetime Superalgebras
We provide a classification of the IIB Dpand NSp-branes in which the brane action exists due to a non-trivial class of the Chevalley-Eilenberg cohomology of free differential algebras. We then present a new geometric formulation of the IIB Dpand NSp-branes (p ≤ 5) in which the manifestly superinvariant Wess-Zumino terms are constructed in terms of the supersymmetric currents. The supercurrents ...
متن کاملComments on (Non-)Chiral Gauge Theories and Type IIB Branes
We use type IIB brane configurations which were recently suggested by Hanany and Zaffaroni to study four dimensional N=1 supersymmetric gauge theories. We calculate the one loop beta function and realize Seiberg’s duality using a particular configuration. We also comment on the anomaly cancelation condition in the case of chiral theories and the beta function in the case of chiral and SO/Sp the...
متن کاملType IIB Seven–brane Solutions from Nine-dimensional Domain Walls
We investigate half–supersymmetric domain wall solutions of four maximally supersymmetric D=9 massive supergravity theories obtained by Scherk–Schwarz reduction of D=10 IIA and IIB supergravity. One of the theories does not have a superpotential and does not allow domain wall solutions preserving any supersymmetry. The other three theories have superpotentials leading to half–supersymmetric dom...
متن کاملSupersymmetric Index and s-rule for Type IIB Branes
We investigate the supersymmetric index of N=2, 3 SU(n) supersymmetric Yang-Mills Chern Simons theories at level k by using the brane configuration with a (p, q)5-brane. We can explain that the supersymmetry breaking occurs when k < n in terms of the s-rule for Type IIB branes. The supersymmetric index coincides with the number of the possible supersymmetric brane configurations. We also discus...
