Abstract

We consider non‐supersymmetric large N orientifold field theories. Specifically, we discuss a gauge theory with a Dirac fermion in the anti‐symmetric tensor representation. We argue that, at large N and in a large part of its bosonic sector, this theory is non‐perturbatively equivalent to 𝒩 = 1 SYM, so that exact results established in the latter (parent) theory also hold in the daughter orientifold theory. In particular, the non‐supersymmetric theory has an exactly calculable bifermion condensate, exactly degenerate parity doublets, and a vanishing cosmological constant (all this to leading order in 1 / N).

## Abstract We review the string construction of the “orientifold field theories” and we show that for these theories the gauge/gravity correspondence is only valid for a large number of colours.

We propose a gauge theory of gravitation. The gauge potential is a connection of the Super SL 2,C group. A Ž . MacDowell-Mansouri type of action is proposed where the action is quadratic in the Super SL 2,C curvature and depends Ž . Ž . purely on gauge connection. By breaking the symmetry of the Su
