“…The metastable states cannot be directly followed from weak 't Hooft coupling to strong 't Hooft coupling, but they quite plausibly match on to strong-coupling analogues where the SUSY breaking is well described by the presence of anti-D3 branes, and a picture very similar to the one in [3]. In addition, the quivers that arise in our construction are some of the simplest cases where the new string instanton effects explored in many recent works make important contributions.…”

“…As originally discussed in [3], and recently applied in similar contexts by many authors, a natural way to construct metastable non-supersymmetric vacua is by adding anti-branes. The positive vacuum energy is proportional to the number of such branes.…”

“…Several of the examples are stringy constructions which involve brane dynamics and/or fluxes in a nontrivial gravitational background [1,2,3,4,5,6,7]. There are also purely field-theoretic constructions, like the Intriligator-Seiberg-Shih (ISS) models [8] where strong/weak coupling dualities [9] allow one to find such states, or the retrofitted models [10] where canonical theories like O'Raifeartaigh or Polonyi models can be coupled to additional dynamics in a way that naturally produces an exponentially small SUSY breaking scale.…”

We consider quiver gauge theories arising on D-branes at simple Calabi-Yau singularities (quotients of the conifold). These theories have metastable supersymmetry breaking vacua. The field theoretic mechanism is basically the one exhibited by the examples of Intriligator, Seiberg and Shih in SUSY QCD. In a dual description, the SUSY breaking is captured by the presence of anti-branes. In comparison to our earlier related work, the main improvements of the present construction are that we can reach the free magnetic range of the SUSY QCD theory where the existence of the metastable vacua is on firm footing, and we can see explicitly how the small masses for the quark flavors (necessary to the existence of the SUSY breaking vacua) are dynamically stabilized. One crucial mass term is generated by a stringy instanton. Finally, our models naturally incorporate R-symmetry breaking in the non-supersymmetric vacuum, in a way similar to the examples of Kitano, Ooguri and Ookouchi.

“…The simplest (though not realistic) choice is a stack of D3 or D3 branes. The antibrane positions are stabilized at the bottom of the SM throat by the warp factor [52,87], and D3-brane positions can be stabilized by nonperturbative physics [11]. Additionally, if there is an orbifold fixed point at the center of the throat, the SM branes can be pinned to the fixed point.…”

Stringy effects during inflation and reheating

We consider inflationary cosmology in the context of string compactifications with multiple throats. In scenarios where the warping differs significantly between throats, string and Kaluza-Klein physics can generate potentially observable corrections to the cosmology of inflation and reheating. First we demonstrate that a very low string scale in the ground state compactification is incompatible with a high Hubble scale during inflation, and we propose that the compactification geometry is altered during inflation. In this configuration, the lowest scale is just above the Hubble scale, which is compatible with the effective field theory but still leads to potentially observable cosmic microwave background corrections. Also in the appropriate region of parameter space, we find that reheating leads to a phase of long open strings in the standard model sector (before the usual radiation-dominated phase). We sketch the cosmology of the long string phase and we discuss possible observational consequences.

“…Many attempts have been made to obtain cascades which break supersymmetry. Some of these involve deforming the KS cascade by adding anti-D3 branes [8] yielding a meta stable SUSY breaking vacuum. Others use different backgrounds finding SUSY breaking in the form of runaways [9,10,11,12,13] which in some cases can be stabilized by hand at the end of the cascade [14].…”

New self-dualities and duality cascades

New self-dualities involving two index tensors are derived. These new self-dualities are used to build various duality cascades. Both vector like and chiral cascades are presented. Aside from ending in confinement, these duality cascades can also end in interacting conformal field theories, free field theories, and meta-stable supersymmetry breaking. Higgsing effects are built into the self-duality so that when the gauge groups are small enough, supersymmetry is broken through the rank condition. Dynamical supersymmetry restoration occurs far from the SUSY breaking vacuum resulting in a long lived meta-stable vacuum. It is found that Coulomb branches are critical in the stabilization of runaways and dynamical supersymmetry restoration.
