Monte Carlo simulation of the Sivers effect in high-energy proton-proton collisions

Andrea Bianconi, Marco Radici

We present Monte Carlo simulations of the Sivers effect in the polarized Drell-Yan process at the center-of-mass energy GeV reachable at…

Cross sections, error bars and event distributions in simulated Drell-Yan azimuthal asymmetry measurements

Andrea Bianconi

A short summary of results of recent simulations of (un)polarized Drell-Yan experiments is presented here. Dilepton production in , , and scattering is…

Crack initiation in elastic bodies

Antonin Chambolle, Alessandro Giacomini, Marcello Ponsiglione

In this paper we study the crack initiation in a hyper-elastic body governed by a Griffith's type energy. We prove that, during a load process through a time dependent boundary dat…

A density result for Sobolev spaces in dimension two, and applications to stability of nonlinear Neumann problems

Alessandro Giacomini, Paola Trebeschi

We prove that if $\Om \subseteq \R^2$ is bounded and $\R^2 \setminus \Om$ satisfies suitable structural assumptions (for example it has a countable number of connected components),…

Non prefix-free codes for constrained sequences

Marco Dalai, Riccardo Leonardi

In this paper we consider the use of variable length non prefix-free codes for coding constrained sequences of symbols. We suppose to have a Markov source where some state transiti…

First Results on 12Lambda-C production at DAPHNE

FINUDA Collaboration

Lambda-hypernuclei are produced and studied, with the FINUDA spectrometer, for the first time at an e+e- collider: DAPHNE, the Frascati phi-factory. The slow negative kaons from ph…

Monte Carlo simulation of events with Drell-Yan lepton pairs from antiproton-proton collisions: the fully polarized case

Andrea Bianconi, Marco Radici

In this paper, we extend the study of Drell-Yan processes with antiproton beams already presented in a previous work. We consider the fully polarized $\bar{p}^\uparrow p^\uparrow \…

Spin physics with antiprotons

M. Maggiora

New possibilities arising from the availability at GSI of antiproton beams, possibly polarised, are discussed. The investigation of the nucleon structure can be boosted by accessin…

A nonlinear model dynamics for closed-system, constrained, maximal-entropy-generation relaxation by energy redistribution

Gian Paolo Beretta

We discuss a nonlinear model for the relaxation by energy redistribution within an isolated, closed system composed of non-interacting identical particles with energy levels e_i wi…
