31 Oct 2011 | Abstract: | A realistic study of the SiDIS process 3He(e,e’pi)X in the Bjorken limit is
briefly reviewed, showing that the nuclear effects, present in the extraction
of the neutron information, are largely under theoretical control, within an
Impulse-Approximation approach. In view of the forthcoming experimental data,
we shortly present a novel Poincare’ covariant description of the nuclear
target, implementing a Light-Front analysis at finite Q^2, within the
Bakamijan-Thomas construction of the Poincare’ generators. Furthermore, as a
by-product of the introduction of a Light-Front spin-dependent spectral
function for a J=1/2 system, we straightforwardly extend our analysis to the
quark-quark correlator, obtaining three new exact relations between the six
leading-twist Transverse-Momentum Dependent distributions. | Source: | arXiv, 1110.6757 | Services: | Forum | Review | PDF | Favorites |
