Overview of SIDIS results from Hall B at Jefferson Lab
- Thomas Jefferson National Accelerator Facility (TJNAF), Newport News, VA (United States)
We present studies of spin and azimuthal asymmetries in pion production in semi-inclusive deep inelastic scattering (SIDIS), using the data sets from the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab with polarized $$NH_3$$ and unpolarized hydrogen targets. Three run periods, e1-6, e1-f and eg1-dvcs used respectively 5.7, 5.5 and 5.8 GeV longitudinally polarized electron beam and unpolarized liquid hydrogen (e1-6, e1-f) and polarized $$NH_3$$ (eg1-dvcs) targets. Pion channels ($$\pi^+$$, $$\pi^-$$, $$\pi^0$$) were studied over a broad kinematical range ($x = 0.1 - 0.6$, $Q^2 = 1.0 - 4.5 $ GeV$^2$, $z = 0.0 - 1.0$, $$\Phperp^2 = 0.0 - 1.0$$ GeV$^2$, and $$-180^\circ < \phi < 180^\circ$$). These measurements give insights into the transverse momentum dependence of parton distribution functions (PDFs) for different polarization states, describing the dynamics of quarks and gluons inside of the proton.
