On the trace identity in a model with broken symmetry

Daniel H. T. Franco

Considering the simple chiral fermion meson model when the chiral symmetry is explicitly broken, we show the validity of a trace identity -- to all orders of perturbation theory --…

Graviton scattering in matrix theory and supergravity

M. Fabbrichesi

I briefly review recent work on the comparison between two and three graviton scattering in supergravity and matrix theory

The Nonlinear Schrodinger Equation on the Half Line

M. Gattobigio, A. Liguori, M. Mintchev

The nonlinear Schrodinger equation on the half line with mixed boundary condition is investigated. After a brief introduction to the corresponding classical boundary value problem,…

Large N QCD from Rotating Branes

Csaba Csaki, Yaron Oz, Jorge Russo +1

We study large N SU(N) Yang-Mills theory in three and four dimensions using a one-parameter family of supergravity models which originate from non-extremal rotating D-branes. We sh…

N=8 BPS black holes preserving 1/8 supersymmetry

M. Bertolini, P. Fre`, M. Trigiante

In the context of N=8 supergravity we consider BPS black-holes that preserve 1/8 supersymmetry. It was shown in a previous paper that, modulo U-duality transformations of E_{7(7)}…

D-strings in unconventional type I vacuum configurations

M. Bianchi, E. Gava, J. F. Morales +1

We determine the spectrum of D-string bound states in various classes of generalized type I vacuum configurations with sixteen and eight supercharges. The precise matching of the B…
