Phenomenology of deflected anomaly-mediation
Riccardo Rattazzi, Alessandro Strumia, James D. Wells
We explore the phenomenology of a class of models with anomaly-mediated supersymmetry breaking. These models retain the successful flavor properties of the minimal scenario while a…
Search for the Charged Higgs Boson in the Decays of Top Quark Pairs in the and Channels at =1.8 TeV
T. Affolder
Top quark production offers the unique opportunity to search for a charged Higgs boson (), as the contribution from can be large in extensions of the St…
Cooling flows and quasars: II. Detailed models of feedback modulated accretion flows
L. Ciotti, J. P. Ostriker
Most elliptical galaxies contain central black holes (BHs), and most also contain significant amounts of hot gas capable of accreting on to the central BH due to cooling times shor…
Bilocal Dynamics for Self-Avoiding Walks
Sergio Caracciolo, Maria Serena Causo, Giovanni Ferraro +2
We introduce several bilocal algorithms for lattice self-avoiding walks that provide reasonable models for the physical kinetics of polymers in the absence of hydrodynamic effects.…
Analytical properties of the R^(1/m) luminosity law
L. Ciotti, G. Bertin
In this paper we describe some analytical properties of the R^{1/m} law proposed by Sersic (1968) to categorize the photometric profiles of elliptical galaxies. In particular, we p…
Baryogenesis through leptogenesis
Riccardo Barbieri, Paolo Creminelli, Alessandro Strumia +1
Baryogenesis by heavy-neutrino decay and sphaleron reprocessing of both baryon and lepton number is reconsidered, paying special attention to the flavour structure of the general e…
