Exploring the phase structure of lattice QCD with twisted mass quarks
F. Farchioni, C. Urbach, R. Frezzotti +7
The phase structure of zero temperature twisted mass lattice QCD is investigated. We find strong metastabilities in the plaquette observable when the untwisted quark mass sweeps ac…

String Theory and ALE Instantons
M. Bianchi, F. Fucito, G. C. Rossi +1
We show that the classical equations of motion of the low-energy effective field theory describing the massless modes of the heterotic (or type I) string admit two classes of super…

ALE Instantons in String Theory
M. Bianchi, F. Fucito, G. C. Rossi +1
In this talk we will describe a string solution which contains a self-dual (instantonic) metric and study its properties. Talk given by M.Bianchi at the Seventh Marcel Grossmann Me…
