Towards an Improved Description of SiDIS by a Polarized 3He Target

LEPTO and Polarized SIDIS

Hadron production in the LEPTO event generator is modeled as a product of distribution functions and LUND hadronization functions (LHF) weighted by the hard scattering cross sections. The description of polarized SIDIS within this formalism includes a new nonperturbative input – polarized LHF’s. It is shown that this approach does not exactly correspond to the commonly adopted one with the inde...

THE SLAC HIGH–DENSITY GASEOUS POLARIZED 3He TARGET*

A large-scale high-pressure gaseous 3He polarized target has been developed for use with a high-intensity polarized electron beam at the Stanford Linear Accelerator Center. This target was used successfully in an experiment to study the spin structure of the neutron. The target provided an areal density of about 7×1021 nuclei/cm2 and operated at 3He polarizations between about 30% and 40% for t...

Extraction of Polarized Parton Densities from Polarized Dis and Sidis

We present results on the quark and gluon polarization in the nucleon obtained in a combined next to leading order analysis to the available inclusive and semi-inclusive polarized deep inelastic scattering data.

Thermodynamic properties of polarized liquid 3He along different isentropic paths

The dependence of some thermodynamic properties of spin-polarized liquid 3He such as velocity of sound, adiabatic index, isentropic compressibility and temperature on the spin polarization has been investigated along different isentropic paths. The Lennard-Jones potential has been used in our calculations. It has been found that for higher values of entropy, the spin polarization has greate...
