Hawking fluxes, Fermionic currents, W(1+infinity) algebra and anomalies

L. Bonora, M. Cvitan, S. Pallua +1

We complete the analysis carried out in previous papers by studying the Hawking radiation for a Kerr black-hole carried to infinity by fermionic currents of any spin. We find agree…

Decoupling A and B model in open string theory -- Topological adventures in the world of tadpoles

Giulio Bonelli, Andrea Prudenziati, Alessandro Tanzini +1

In this paper we analyze the problem of tadpole cancellation in open topological strings. We prove that the inclusion of unorientable worldsheet diagrams guarantees a consistent de…

Comparison of renormalization group schemes for sine-Gordon type models

I. Nandori, S. Nagy, K. Sailer +1

The scheme-dependence of the renormalization group (RG) flow has been investigated in the local potential approximation for two-dimensional periodic, sine-Gordon type field-theoric…

Effective potentials and kink spectra in non-integrable perturbed conformal field theories

G. Mussardo, G. Takacs

We analyze the evolution of the effective potential and the particle spectrum of two-parameter families of non-integrable quantum field theories. These theories are defined by defo…

Fixed Points of Nonlinear Sigma Models in d>2

A. Codello, R. Percacci

Using Wilsonian methods, we study the renormalization group flow of the Nonlinear Sigma Model in any dimension , restricting our attention to terms with two derivatives. At one…

The decay-time of non-commutative micro-black holes

Roberto Casadio, Piero Nicolini

Non-commutative black holes are characterised by a minimum mass which would result in a remnant after the Hawking evaporation ends. We numerically study the decay of neutral non-co…
