IIA perspective on cascading gauge theory

We study the N = 1 supersymmetric cascading gauge theory found in type IIB string theory on p regular and M fractional D3-branes at the tip of the conifold, using the T-dual type IIA description. We

Thermal evolution of the non-supersymmetric metastable vacua in N = 2 SU(2) SYM softly broken to N = 1

: It has been shown that four dimensional N = 2 gauge theories, softly broken to N = 1 by a superpotential term, can accommodate metastable non-supersymmetric vacua in their moduli space. We study

Gravitational correction to fuzzy string in metastable brane configuration

We study dynamics of a cosmic string in a metastable brane configuration in Type IIA string theory. We first discuss a decay process of the cosmic string via a fuzzy brane (equivalently bubble/string

Tree level metastability and gauge mediation in baryon deformed SQCD

We investigate supersymmetric QCD with gauge group SU(2) and a baryon deformation to the superpotential. The existence of an uplifted vacuum at the origin with tree level metastability is

Solitonic supersymmetry restoration

Q-balls are a possible feature of any model with a conserved, global U(1) symmetry and no massless, charged scalars. It is shown that for a broad class of models of metastable supersymmetry breaking

On uplifted SUSY-breaking vacua and direct mediation in generalized SQCD

We search for viable models of direct gauge mediation, where the SUSY-breaking sector is (generalized) SQCD, which has cosmologically favorable uplifted vacua even when the reheating temperature is

Gauge/Gravity Duality and Field Theories at Strong Coupling

In this thesis, we apply the gauge/string duality in its supergravity limit to infer some properties of field theories at strong coupling. Experiments at RHIC and at the LHC indeed suggest that the

T-dualizing the deformed and resolved conifold

In a previous paper, we used T-duality to construct a new type of 1/4-BPS solution describing a pair of NS5-branes intersecting in 1 + 3 dimensions and localized in all other directions except for a

Thermal evolution of the non-supersymmetric metastable vacua in $ \mathcal{N}=2 $ SU(2) SYM softly broken to $ \mathcal{N}=1 $

A bstractIt has been shown that four dimensional $ \mathcal{N}=2 $ gauge theories, softly broken to $ \mathcal{N}=1 $ by a superpotential term, can accommodate metastable non-supersymmetric vacua in

Brane dynamics and gauge theory

The authors review some aspects of the interplay between the dynamics of branes in string theory and the classical and quantum physics of gauge theories with different numbers of supersymmetries in

Non-supersymmetric meta-stable vacua from brane configurations

We construct configurations of NS-, D4-, and D6-branes in type IIA string theory, realizing the recently discussed non-supersymmetric meta-stable minimum of 4d = 1 SU(Nc) super-Yang-Mills theories

Dynamical SUSY breaking in meta-stable vacua

Dynamical supersymmetry breaking in a long-lived meta-stable vacuum is a phenomenologically viable possibility. This relatively unexplored avenue leads to many new models of dynamical supersymmetry

Holography for Non-Critical Superstrings

We argue that a class of ``non-critical superstring'' vacua is holographically related to the (non-gravitational) theory obtained by studying string theory on a singular Calabi-Yau manifold in the

SUSY breaking by a metastable ground state: why the early Universe preferred the non-supersymmetric vacuum

Supersymmetry breaking in a metastable vacuum is re-examined in a cosmological context. It is shown that thermal effects generically drive the Universe to the metastable minimum even if it begins in
