D-branes in B Fields
نویسنده
چکیده
The RR Page charges for the D2-, D4-, D6-brane in B fields are constructed explicitly from the equations of motion and the nonvanishing (modified) Bianchi identities by exploiting their properties — conserved and localized. It is found that the RR Page charges are independent of the backgound B fields, which provides further evidence that the RR Page charge should be quantized. In our construction, it is highly nontrivial that the terms like B ∧B ∧B, B ∧B ∧ F , B ∧ F ∧ F from different sources are exactly cancelled with each other. ∗e-mail address: [email protected]

متن کاملSupergravity Couplings of Noncommutative D-branes
We discuss the supergravity couplings of noncommutative D-branes by considering the disk amplitudes with one closed string insertion. The result confirms a recent proposal for the general form of the noncommutative Yang-Mills operators coupling to the massless closed string modes. The construction involves smearing Yang-Mills field variables along an open Wilson line. For multiple D-branes inte...

We construct quantum mechanical models which mimic many features of string theory. We use these models to gain improved descriptions of B fields and gerbes. We examine the analogs of T duality, D branes, and mirror symmetry in these models and derive quantum mechanical analogs of standard phenomena, such as the noncommutative geometry induced by a B field.
متن کاملD-Term Supersymmetry Breaking from Branes
Metastable supersymmetry breaking configurations of D-branes and NS5-branes in string theory often owe their existence to classical gravitational interactions between the branes. We show that in the effective theory of the light fields, these interactions give rise to a noncanonical Kähler potential and other D-terms. String theory provides a UV completion in which these non-renormalizable term...

متن کاملIntersecting Noncommutative D-branes and Baryons in Magnetic Fields
We study supersymmetric intersecting configurations of D-branes with B-field backgrounds. Noncommutative D-brane or M-brane pairs can intersect supersymmetrically over (p − 1)-brane, as well as over (p − 2)brane like ordinary branes. d = 10 and d = 11 supergravity solutions are obtained and the supersymmetry projection rule is examined. As an application we study a noncommutative D7-brane probe...
