SUSY-breaking Soft Terms in a MSSM Magnetized D7-brane Model
نویسنده
چکیده
We compute the SUSY-breaking soft terms in a magnetized D7-brane model with MSSM-like spectrum, under the general assumption of non-vanishing auxiliary fields of the dilaton and Kähler moduli. As a particular scenario we discuss SUSY breaking triggered by ISD or IASD 3-form fluxes.

MSSM with Soft SUSY Breaking Terms from D7–Branes with Fluxes
We discuss the structure of the soft supersymmetry breaking terms in a MSSM like model, which can be derived from D7–branes with chiral matter fields from 2–form f–fluxes and supersymmetry breaking from 3-form G–fluxes.
متن کاملModulus-dominated SUSY-breaking soft terms in F-theory and their test at LHC
We study the general patterns of SUSY-breaking soft terms arising under the assumption of Kahler moduli dominated SUSY-breaking in string theory models. Insisting that all MSSM gauginos get masses at leading order and that the top Yukawa coupling is of order the gauge coupling constant identifies the class of viable models. These are models in which the SM fields live either in the bulk or at t...
متن کاملFlux-induced SUSY-breaking soft terms on D7-D3 brane systems
We study the effect of RR and NSNS 3-form fluxes on the effective action of the worldvolume fields of Type IIB D7/D3-brane configurations. The D7-branes wrap 4-cycles Σ4 on a local Calabi-Yau geometry. This is an extension of previous work on hep-th/0311241, where a similar analysis was applied to the case of D3-branes. Our present analysis is based on the D7and D3-brane Dirac-Born-Infeld and C...
متن کاملNon-universal Soft Parameters in Brane World and the Flavor Problem in Supergravity
We consider gravity mediated supersymmetry (SUSY) breaking in 5D spacetime with two 4D branes B1 and B2 separated in the extra dimension. Using an off-shell 5D supergravity (SUGRA) formalism, we argue that the SUSY breaking scales could be non-universal even at the fundamental scale in brane world setting, since SUSY breaking effects could be effectively localized. As an application, we suggest...
متن کاملModels with Quartic Potential of Dynamical SUSY Breaking in Meta-Stable Vacua
We search for models of dynamical SUSY breaking in meta-stable vacua which might have dual string descriptions with a few brane probes. Two models with quartic superpotential are proposed: One of them might be closely related to the dual gauge theory to the flavored Maldacena-Nuñez geometry by Casero, Nuñez, and Paredes with a few additional brane probes corresponding to massive flavors. The ot...
