A bound on the effective gravitational coupling from semiclassical black holes
R. Brustein, G. Dvali, G. Veneziano
We show that the existence of semiclassical black holes of size as small as a minimal length scale implies a bound on a gravitational analogue of 't-Hooft's coupling $λ_G(…
Towards an S-matrix Description of Gravitational Collapse
D. Amati, M. Ciafaloni, G. Veneziano
Extending our previous results on trans-Planckian () scattering of light particles in quantum string-gravity we present a calculation of the corresponding S-matrix fr…
A note on C-Parity Conservation and the Validity of Orientifold Planar Equivalence
Adi Armoni, Mikhail Shifman, Gabriele Veneziano
We analyze the possibility of a spontaneous breaking of C-invariance in gauge theories with fermions in vector-like - but otherwise generic - representations of the gauge group. QC…
Large N, Supersymmetry ... and QCD
G. Veneziano, J. Wosiek
This paper consists of two (still only vaguely) related parts: in the first, we briefly review work done in the past three years on the ``planar equivalence" between a class of non…
Refining the Proof of Planar Equivalence
A. Armoni, M. Shifman, G. Veneziano
We outline a full non-perturbative proof of planar (large-N) equivalence between bosonic correlators in a theory with Majorana fermions in the adjoint representation and one with D…
A Model for the Big Bounce
G. Veneziano
I motivate a proposal for modeling, at weak string coupling, the ``Big Bounce" transition from a growing-curvature phase to standard (FRW) cosmology in terms of a pressure-less den…
