Centrality Behaviour of J/ Production in Na50

SÉRGIO RAMOS

The J/ production in 158 A GeV Pb-Pb interactions is studied, in the dimuon decay channel, as a function of centrality, as measured with the electromagnetic or with the very for…

Origins of single transverse spin asymmetries

M. Anselmino, M. Boglione, U. D'Alesio +1

Single transverse spin asymmetries in p-p -> pion + X and l-p -> l-pion + X processes have been observed; their possible origins and connections are investigated. A phenomenologica…

Transverse Lambda polarization in semi-inclusive DIS

M. Anselmino, D. Boer, U. D'Alesio +1

Following a previous description of Lambda and Lambda-bar polarization in unpolarized p-p interactions, within a perturbative QCD factorization scheme with new polarizing fragmenta…

Electron-neutrino survival probability from solar-neutrino data

V. Berezinsky, M. Lissia

With SNO data on electron-neutrino flux from the sun, it is possible to derive the survival probability from existing experimental data of Super-Kamiokande, galli…

Longitudinal Lambda polarization in polarized semi-inclusive DIS

M. Anselmino, M. Boglione, U. D'Alesio +1

We calculate, within pQCD parton model at leading orders, the expression of the longitudinal polarization of Lambda baryons produced in polarized semi-inclusive DIS, including weak…

Transverse Lambda polarization in unpolarized semi-inclusive DIS

M. Anselmino, D. Boer, U. D'Alesio +1

The long-standing problem of transverse Lambda polarization in high-energy collisions of unpolarized hadrons can be tackled by considering new, spin and k_T-dependent quark fragmen…

Weak interactions in polarized semi-inclusive DIS

M. Anselmino, M. Boglione, U. D'Alesio +1

We calculate, within pQCD parton model at leading orders, the expression of the polarization P of spin 1/2 hadrons (typically Lambda baryons), produced in polarized semi-inclusive…

Parton Densities and Fragmentation Functions from Polarized Lambda Production in Semi-Inclusive DIS

M. Anselmino, M. Boglione, U. D'Alesio +2

We consider the longitudinal polarization of Lambda and Lambda-bar produced in the current fragmentation region of polarized deep inelastic scattering. We show how the various cros…
