Beam-Target Double-Spin Asymmetry ALT in Charged Pion Production from Deep Inelastic Scattering on a Transversely Polarized 3He Target at 1:4<Q2 < 2:7 GeV2

Gao, Haiyan; Qian, Xin; Chen, Wei; Huang, Min; Qiang, Ye; Zhu, Xiaofeng; Zong, Xing (American Physical Society, 2012-02-03)

We report the first measurement of the double-spin asymmetry ALT for charged pion electroproduction in semi-inclusive deep-inelastic electron scattering on a transversely polarized 3He target. The kinematics focused on the ...
Experimental study of the A(e,e 'pi(+)) reaction on H-1, H-2, C-12, Al-27, Cu-63, and Au-197

Qian, Xin; Dutta, D.; Gao, Haiyan; Kramer, K. (AMER PHYSICAL SOC, 2010)

Cross sections for the H-1(e,e'pi(+))n process on H-1, H-2, C-12, Al-27, Cu-63, and Au-197 targets were measured at the Thomas Jefferson National Accelerator Facility ( Jefferson Lab) to extract nuclear transparencies. ...
Role of mesons in the electromagnetic form factors of the nucleon

Gao, Haiyan; Xu, W. (AMER PHYSICAL SOC, 2010)

The roles played by mesons in the electromagnetic form factors of the nucleon are explored using as a basis a model containing vector mesons with coupling to the continuum together with the asymptotic Q(2) behavior of ...
