BPS-Saturated Bound States of Tilted P-Branes in Type II String Theory
نویسندگان
چکیده
We found BPS-saturated solutions of M -theory and Type II string theory which correspond to (non-marginally) bound states of p-branes intersecting at angles different from π/2. These solutions are obtained by starting with a BPS marginally bound (orthogonally) intersecting configurations of two p-branes (e.g, two fourbranes of Type II string theory), performing a boost transformation at an angle with respect to the world-volume of the configuration, performing T -duality transformation along the boost-direction, S-duality transformation, and T transformations along the direction perpendicular to the boost transformation. The resulting configuration is non-marginally bound BPS-saturated solution whose static metric possesses the off-diagonal term which cannot be removed by a coordinate transformation, and thus signifies an angle (different from π/2) between the resulting intersecting p-branes. Additional new p-branes are bound to this configuration, in order to ensure the stability of such a static, tilted configuration. e-mail: [email protected] e-mail: [email protected]

Mixed Boundary Conditions and Brane, String Bound States
In this article we consider open strings with mixed boundary conditions (a combination of Neumann and Dirichlet at each end), and discuss how their end points show a Dp-brane with NS-NS charge, i.e. a bound state of a D-brane with fundamental strings. We show these branes are BPS saturated. Restricting ourselves to D-string case, their mass density is shown to be BPS saturated, in agreement wit...
متن کاملBPS bound states , supermembranes , and T - duality in M - theory ∗ Jorge
This is an introductory review on the eleven-dimensional description of the BPS bound states of type II superstring theories, and on the role of supermembranes in M-theory. The first part describes classical solutions of 11d supergravity which upon dimensional reduction and T-dualities give bound states of NS-NS and R-R p-branes of type IIA and IIB string theories. In some cases (e.g. (q1, q2) ...

متن کاملNon-BPS States and Branes in String Theory
We review the recent developments in our understanding of non-BPS states and branes in string theory. The topics include 1) construction of unstable non-BPS D-branes in type IIA and type IIB string theories, 2) construction of stable non-BPS D-branes on various orbifolds and orientifolds of type II string theories, 3) description of BPS and non-BPS D-branes as tachyonic soliton solutions on bra...
متن کاملD-Brane Bound States Redux
We study the existence of D-brane bound states at threshold in Type II string theories. In a number of situations, we can reduce the question of existence to quadrature, and the study of a particular limit of the propagator for the system of D-branes. This involves a derivation of an index theorem for a family of non-Fredholm operators. In support of the conjectured relation between compactifie...
