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…

On the stability of thick brane worlds non-minimally coupled to gravity

A. A. Andrianov, Luca Vecchi

We analyze a class of 5D models where a 3 brane is generated by a bulk scalar field non minimally coupled to gravity. We show that perturbative stability of such branes is normally…

Remarks on confinement driven by axion-like particles in Yang-Mills theories

Patricio Gaete, Euro Spallucci

Features of screening and confinement are studied for a non-Abelian gauge theory with a mixture of pseudoscalar and scalar coupling, in the case where a constant chromo-electric, o…

Isomorphism of critical and off-critical operator spaces in two-dimensional quantum field theory

G. Delfino, G. Niccoli

For the simplest quantum field theory originating from a non-trivial fixed point of the renormalization group, the Lee-Yang model, we show that the operator space determined by the…

Massive states as the relevant deformations of gravitating branes

Luca Vecchi

Five-dimensional theories manifesting spontaneous brane generation are discussed in a gravitational context. Without gravity, the IR dynamics of the brane fluctuation below the bra…

New non-abelian effects on D branes

Roberto Iengo, Jorge G. Russo

We extend the Myers dielectric effect to configurations with angular momentum. The resulting time-dependent N D0 brane bound states can be interpreted as describing rotating fuzzy…
