Partial N=2 --> N=1 Local Supersymmetry Breaking and Solvable Lie Algebras

P. Fre', L. Girardello, I. Pesando +1

Generic partial supersymmetry breaking of N=2 supergravity with zero vacuum energy and with surviving unbroken arbitrary gauge groups is exhibited. Specific examples are given.

Scattering Amplitudes and the CPT theorem in String Theory

A. Pasquinucci, K. Roland

We discuss the role of the CPT transformation in first quantized string theories, both on the world-sheet and in the space-time. We explicitly show that the space-time CPT theorem…

Quantizing N=2 matter-supergravity systems

M. T. Grisaru, A. Santambrogio, D. Zanon

We consider supergravity coupled to Yang--Mills matter and discuss the nature of one--loop divergences. Using superfields and superspace methods, we describe the…

Gauge invariant action at the ultraviolet cutoff

M. Bonini, G. Marchesini

We show that it is possible to formulate a gauge theory starting from a local action at the ultraviolet (UV) momentum cutoff which is BRS invariant. One has to require that fields…

String Theory and the CPT Theorem on the World-Sheet

Andrea Pasquinucci, Kaj Roland

We study the CPT theorem for a two-dimensional conformal field theory on an arbitrary Riemann surface. On the sphere the theorem follows from the assumption that the correlation fu…

Velocity field and operator in (non relativistic) quantum mechanics

Giovanni Salesi, Erasmo Recami

Starting from the formal expressions of the hydrodynamical (or ``local'') quantities employed in the applications of Clifford Algebras to quantum mechanics, we introduce --in terms…

Spontaneous N=2 --> N=1 local supersymmetry breaking with surviving local gauge group

P. Fre', L. Girardello, I. Pesando +1

Generic partial supersymmetry breaking of supergravity with zero vacuum energy and with surviving unbroken arbitrary gauge groups is exhibited. Specific examples are given.

Renormalization Group Flows in Sigma--Models Coupled to Two--Dimensional Dynamical Gravity

S. Penati, A. Santambrogio, D. Zanon

We consider a bosonic $\s$--model coupled to two--dimensional gravity. In the semiclassical limit, , we compute the gravity dressing of the $\b$--functions at…

The BF Formalism for QCD and Quark Confinement

F. Fucito, M. Martellini, M. Zeni

Using the BF version of pure Yang-Mills, it is possible to find a covariant representation of the 't Hooft magnetic flux operator. In this framework, 't Hooft's pioneering work on…

Beta function and infrared renormalons in the exact Wilson renormalization group in Yang-Mills theory

M. Bonini, G. Marchesini, M. Simionato

We discuss the relation between the Gell-Mann-Low beta function and the ``flowing couplings'' of the Wilsonian action of the exact renormalization group (RG) at the scale…

The Quantization of Anomalous Gauge Field Theory and BRST-invariant Models of Two Dimensional Quantum Gravity

M. Martellini, K. Yoshida, M. Spreafico

We analyze the problems with the so called gauge invariant quantization of the anomalous gauge field theories originary due to Faddeev and Shatashvili (FS). Our analysis bring to a…

Explicit Construction of Yang-Mills Instantons on ALE Spaces

Massimo Bianchi, Francesco Fucito, Maurizio Martellini +1

We describe the explicit construction of Yang-Mills instantons on ALE spaces, following the work of Kronheimer and Nakajima. For multicenter ALE metrics, we determine the abelian i…
