Supersymmetric Index and s-rule for Type IIB Branes
نویسنده
چکیده
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 discuss a construction of a family of theories which have the same supersymmetric index. e-mail address: [email protected]

More on supersymmetric D-branes in type IIB plane wave background
We extend the study on D-branes in the type IIB plane wave background to less supersymmetric configurations. We show that many new supersymmetric D-branes can be found by turning on electric as well as magnetic background fluxes, or constantly boosting D-branes.
متن کاملGravity Dual of Superconformal Anomaly
The supergravity dual of superconformal anomaly in a four-dimensional supersymmetric gauge theory is investigated. We consider a well-established dual correspondence between the N = 1 SU(N +M) × SU(N) supersymmetric gauge theory with two flavors of matter fields in the bifundamental representation of gauge group and type IIB superstring in the space-time background furnished by the Klebanov-Str...
متن کاملSuperembedding approach to superstring in AdS 5 × S 5 superspace
We review the spinor moving frame formulations and generalized action principle for super-p-branes, describe in detail the superembedding approach to superstring in general type IIB supergravity background and present the complete superembedding description of type IIB superstring in the AdS5 × S 5 superspace. This contribution is devoted to the memory of Wolfgang Kummer who untimely left us in...
متن کاملOn superembedding approach to type IIB 7–branes
In search for a dynamical description of Q7-branes, which were known as solutions of supergravity equations and then conjectured to be dynamical objects of type IIB string theory, we study the superembedding description of 7-branes in curved type IIB supergravity superspace. With quite minimal and natural assumptions we have found that there is no place for Q7-branes as dynamical branes in supe...
متن کاملD-branes, Supersymmetry Breaking, and Neutrinos
This thesis studies metaand exactly stable supersymmetry breaking mechanisms in heterotic and type IIB string theories and constructs an F-theory Grand Unified Theory model for neutrino physics in which neutrino mass is determined by the supersymmetry breaking mechanism. Focussing attention on heterotic string theory compactified on a 4-torus, stability of non-supersymmetric states is studied. ...
