Dirac Action on M 5 and M 2 Branes with Bulk Fluxes
نویسنده
چکیده
We derive an explicit form of the quadratic-in-fermions Dirac action on the M5 brane for an arbitrary on-shell background of 11D supergravity with non-vanishing fluxes and in presence of a chiral 2-form on M5. This action may be used to generalize the conditions for which the non-perturbative superpotential can be generated in M/string theory. We also derive the Dirac action with bulk fluxes on the M2 brane.

T-duality and the Worldvolume Solitons of Five-Branes and KK-Monopoles
We show that the fluxes of the various six-dimensional “gauge” theories are associated to below threshold bound states of D-branes with the NS-5-branes and KK-monopoles which preserve half of bulk supersymmetry. We then present the supergravity solutions that correspond to these bound states. In addition using the worldvolume solitons of IIA and IIB NS-5-branes and KK-monopoles, we investigate ...
متن کاملF-theory Flux, Destabilization of Orientifolds and Soft Terms on D7–Branes
We use F-theory to derive a general expression for the flux potential of type II compactifications with D7/D3 branes, including open string moduli and 2-form fluxes on the branes. Our main example is F-theory on K3 × K3 and its orientifold limit T /Z2× K3. The full scalar potential cannot be derived from the bulk superpotential W = ∫ Ω ∧G3 and generically destabilizes the orientifold. Generical...

The cosmology in the Hubble expansion era of the Horava-Witten M-theory compactified on a Calabi-Yau threefold is studied in the reduction to five-dimensions where the effects of the Calabi-Yau man-ifold are summarized by the volume modulus, and all perturbative potentials are included. Matter on the branes are treated as first order perturbations of the static vacuum solution, and all equation...
متن کاملRemarks on Anti - De Sitter D - Branes
We present some preliminary investigations about the AdS 2 ×S 2 D3-branes in AdS 3 ×S 3. We analyse the quadratic fluctuations of Dirac–Born–Infeld action around a given semi-classical D-brane configuration and compare them with results obtained by using conformal-field-theory techniques. We finally study classical motions of open strings attached to those D-branes and analyse the rôle of the s...
متن کاملGeometric Transition, Large N Dualities and MQCD Dynamics
We study Vafa’s geometric transition from a brane setup in M-theory. In this transition D5 branes wrapped on P cycles of a resolved conifold disappear and are replaced by fluxes on a deformed conifold. In the limit of small sized P, we describe this mechanism as a transition from curved M5 branes to plane M5 branes which replaces SU(N) MQCD by U(1) theories on the bulk. This agrees with the res...
