Non-Perturbative Planar Equivalence and the Absence of Closed String Tachyons
Adi Armoni
We consider 'orbifold' and 'orientifold' field theories from the dual closed string theory side. We argue that a necessary condition for planar equivalence to hold is the absence o…
An Exact Relation for N=1 Orientifold Field Theories with Arbitrary Superpotential
A. Armoni, A. Gorsky, M. Shifman
We discuss a nonperturbative relation for orientifold parent/daughter pairs of supersymmetric theories with an arbitrary tree-level superpotential. We show that super-Yang-Mills (S…
Remarks on Stable and Quasi-stable k-Strings at Large N
A. Armoni, M. Shifman
We discuss k-strings in the large-N Yang-Mills theory and its supersymmetric extension. Whereas the tension of the bona fide (stable) QCD string is expected to depend only on the N…
SUSY Relics in One-Flavor QCD from a New 1/N Expansion
A. Armoni, M. Shifman, G. Veneziano
We suggest a new large-N_c limit for multi flavor QCD. Since fundamental and two-index antisymmetric representations are equivalent in SU(3), we have the option to define SU(N_c) Q…
On k-String Tensions and Domain Walls in N=1 Gluodynamics
A. Armoni, M. Shifman
We discuss the k dependence of the k-string tension sigma_k in SU(N) supersymmetric gluodynamics. As well known, at large N the k-string consists, to leading order, of k noninterac…
The Cosmological Constant and Domain Walls in Orientifold Field Theories and N=1 Gluodynamics
A. Armoni, M. Shifman
We discuss domain walls and vacuum energy density (cosmological constant) in N=1 gluodynamics and in non-supersymmetric large N orientifold field theories which have been recently…
