K theory and Ramond-Ramond charge

- R. Minasian, G. Moore
- Physics
- 30 October 1997

We discuss the relation between the Ramond-Ramond charges of D-branes and the topology of Chan-Paton vector bundles. We show that a topologically nontrivial normal bundle induces RR charge and that… Expand

Generalized structures of N=1 vacua

- M. Graña, R. Minasian, M. Petrini, A. Tomasiello
- Physics, Mathematics
- 24 May 2005

We characterize = 1 vacua of type-II theories in terms of generalized complex structure on the internal manifold M. The structure group of T(M)⊕T*(M) being SU(3) × SU(3) implies the existence of two… Expand

The baryonic branch of Klebanov-Strassler solution: a supersymmetric family of SU(3) structure backgrounds

- A. Butti, M. Graña, R. Minasian, M. Petrini, A. Zaffaroni
- Physics
- 16 December 2004

We exhibit a one-parameter family of regular supersymmetric solutions of type IIB theory that describes the baryonic branch of the Klebanov-Strassler (KS) theory. The solution is obtained by applying… Expand

Eleven-dimensional origin of string-string duality: A One loop test

- M. Duff, J. Liu, R. Minasian
- Physics
- 19 June 1995

Abstract Membrane/ fivebrane duality in D = 11 implies Type IIA string/Type IIA fivebrane duality in D = 10, which in turn implies Type HA string/heterotic string duality in D = 6. To test the… Expand

Nonlinear instantons from supersymmetric p-branes

- M. Mariño, R. Minasian, G. Moore, A. Strominger
- Physics
- 25 November 1999

Supersymmetric configurations of type II D-branes with nonzero gauge field strengths in general supersymmetric backgrounds with nonzero B fields are analyzed using the kappa-symmetric worldvolume… Expand

A scan for new N = 1 vacua on twisted tori

- M. Graña, R. Minasian, M. Petrini, A. Tomasiello
- Physics
- 18 September 2006

We perform a systematic search for N = 1 Minkowski vacua of type II string theories on compact six–dimensional parallelizable nil– and solvmanifolds (quotients of six–dimensional nilpotent and… Expand

T-duality, generalized geometry and non-geometric backgrounds

- M. Graña, R. Minasian, M. Petrini, D. Waldram
- Physics
- 28 July 2008

We discuss the action of O(d,d), and in particular T-duality, in the context of generalized geometry, focusing on the description of so-called non-geometric backgrounds. We derive local expressions… Expand

Non-abelian tensor-multiplet anomalies

- J. Harvey, R. Minasian, G. Moore
- Physics
- 11 August 1998

We use the anomaly cancellation of the M-theory fivebrane to derive the R-symmetry anomalies of the AN (0,2) tensor-multiplet theories. This result leads to a simple derivation of black hole entropy… Expand

Supersymmetric backgrounds from generalized Calabi‐Yau manifolds

- M. Graña, R. Minasian, M. Petrinin, A. Tomasiello
- Chemistry, Mathematics
- 15 July 2005

We show that the supersymmetry transformations for type II string theories on six-manifolds can be written as differential conditions on a pair of pure spinors, the exponentiated Kahler form eiJ and… Expand

String loop corrections to the universal hypermultiplet

- I. Antoniadis, R. Minasian, S. Theisen, P. Vanhove
- Physics
- 28 July 2003

We study loop corrections to the universal dilaton supermultiplet for type IIA strings compactified on Calabi-Yau threefolds. We show that the corresponding quaternionic kinetic terms receive… Expand
