On (multi-)center Branes and Exact String Vacua *
نویسنده
چکیده
Multicenter supergravity solutions corresponding to Higgs phases of supersymmetric Yang–Mills theories are considered. For NS5 branes we identify three cases where there is a description in terms of exact conformal field theories. Other supergravity solutions, such as D3-branes with angular momentum, are understood as special limits of multicenter ones. Within our context we also consider 4-dim gravitational multi-instantons.

AdS and dS Entropy from String Junctions
Flux compactifications of string theory exhibiting the possibility of discretely tuning the cosmological constant to small values have been constructed. The highly tuned vacua in this discretuum have curvature radii which scale as large powers of the flux quantum numbers, exponential in the number of cycles in the compactification. By the arguments of Susskind/Witten (in the AdS case) and Gibbo...
متن کاملD-branes, Supersymmetry Breaking, and Neutrinos
This thesis studies metaand exactly stable supersymmetry breaking mechanisms in heterotic and type IIB string theories and constructs an F-theory Grand Unified Theory model for neutrino physics in which neutrino mass is determined by the supersymmetry breaking mechanism. Focussing attention on heterotic string theory compactified on a 4-torus, stability of non-supersymmetric states is studied. ...
متن کاملModuli stabilization from magnetic fluxes in type I string theory
We show that type I string theory compactified in four dimensions in the presence of constant internal magnetic fields possesses N = 1 supersymmetric vacua, in which all Kähler class and complex structure closed string moduli are fixed. Furthermore, their values can be made arbitrarily large by a suitable tuning of the quantized magnetic fluxes. We present an explicit example for the toroidal c...
متن کاملProgress in D-brane model building
The ‘state of the art’ in D-brane model building is briefly reviewed, focusing on recent achievements in the construction of D = 4N = 1 type II string vacua with semi-realistic gauge sectors. Such progress relies on a better understanding of the spectrum of BPS D-branes, the effective field theory obtained from them and the explicit construction of vacua. We first consider D-branes in standard ...
متن کاملString Theory Duals for Mass - deformed SO ( N ) and USp ( 2 N ) N = 4 SYM Theories
We generalize the results of Polchinski and Strassler regarding the N = 1-preserving mass deformation of N = 4 SU(N) SYM theories and its string theory dual to SO(N) and USp(2N) gauge groups. The string theory duals involve 5-branes wrapped on RP. In order to match with the field theory classification of vacua, the 3-brane charge carried by such 5-branes must be shifted by a half, and this foll...
