Sivers and Collins Effects: from SIDIS to Proton-Proton Inclusive Pion Production

M. Anselmino, M. Boglione, U. D'Alesio +4

We consider the Sivers, Collins and transversity functions as extracted from SIDIS and e+e- experimental data and investigate to what extent they might explain the large Single Spi…

Single spin asymmetries in l p --> h + X processes

M. Anselmino, M. Boglione, U. D'Alesio +3

We study the transverse single spin asymmetry (SSA), A_N, for the single inclusive process l p (transv. polarized) --> h + X, in a perturbative QCD factorization scheme with inclus…

Anti-Matter in Cosmic Rays : Backgrounds and Signals

Timur Delahaye, Pierre Brun, Fiorenza Donato +5

Recent PAMELA and ATIC data seem to indicate an excess in positron cosmic rays above approximately 10 GeV which might be due to galactic Dark Matter particle annihilation. However…

Study of the electromagnetic transition form-factors in η-> μ^+μ^-γand ω-> μ^+μ^-π^0 decays with NA60

NA60 Collaboration, R. Arnaldi

The NA60 experiment at the CERN SPS has studied low-mass muon pairs in 158A GeV In-In collisions. The mass and pT spectra associated with peripheral collisions can quantitatively b…

Transport properties and Langevin dynamics of heavy quarks and quarkonia in the Quark Gluon Plasma

A. Beraudo, A. De Pace, W. M. Alberico +1

Quark Gluon Plasma transport coefficients for heavy quarks and quark-antiquark pairs are computed through an extension of the results obtained for a hot QED plasma by describing th…
