Renormalizability of Nonrenormalizable Field Theories
Alberto Blasi, Nicola Maggiore, Silvio P. Sorella +1
We give a simple and elegant proof of the Equivalence Theorem, stating that two field theories related by nonlinear field transformations have the same S matrix. We are thus able t…
Repairing Broken Algebras
Alberto Blasi, Nicola Maggiore
We consider theories characterized by a set of Ward operators which do not form a closed algebra. We impose the Slavnov--Taylor identity built out of the Ward operators and we deri…
Categorial mirror symmetry for K3 surfaces
C. Bartocci, U. Bruzzo, G. Sanguinetti
We study the structure of a modified Fukaya category associated with a K3 surface , and prove that whenever is an elliptic K3 surface with a section, the deri…
On the strong anomalous diffusion
P. Castiglione, A. Mazzino, P. Muratore-Ginanneschi +1
The superdiffusion behavior, i.e. , with , in general is not completely characherized by a unique exponent. We study some systems exhibiting strong a…
A Search for Heavy Stable and Long-Lived Squarks and Sleptons in e^+ e^- Collisions at Energies from 130 to 183 GeV
DELPHI Collaboration, P. Abreu et al
A search for stable and long-lived heavy charged particles used the data taken by the DELPHI experiment at energies from 130 to 183 GeV. The Cherenkov light detected in the Ring Im…
Lagrangian method for multiple correlations in passive scalar advection
U. Frisch, A. Mazzino, A. Noullez +1
A Lagrangian method is introduced for calculating simultaneous n-point correlations of a passive scalar advected by a random velocity field, with random forcing and finite molecula…
