Softly Massive Gravity
G. Gabadadze, M. Shifman
Large-distance modification of gravity may be the mechanism for solving the cosmological constant problem. A simple model of the large-distance modification -- four-dimensional (4D…
Effective Lagrangians for Orientifold Theories
F. Sannino, M. Shifman
We construct effective Lagrangians of the Veneziano-Yankielowicz (VY) type for two non-supersymmetric theories which are orientifold daughters of supersymmetric gluodynamics (conta…
QCD Quark Condensate from SUSY and the Orientifold Large-N Expansion
A. Armoni, M. Shifman, G. Veneziano
We estimate the quark condensate in one-flavor massless QCD from the known value of the gluino condensate in SUSY Yang-Mills theory using our newly proposed "orientifold" large-N e…
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…
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…
