asymmetries in unpolarized semi-inclusive DIS
Bing Zhang, Zhun Lu, Bo-Qiang Ma +1
We use the Boer-Mulders functions parameterized from unpolarized Drell-Yan data by the FNAL E866/NuSea Collaboration combined with recently extracted Collins functions to cal…
Azimuthal angle dependence of di-jet production in unpolarized hadron scattering
Zhun Lu, Ivan Schmidt
We study the azimuthal angular dependence of back-to-back di-jet production in unpolarized hadron scattering , arising from the product of two Boer-Mulder…
Extracting Boer-Mulders functions from Drell-Yan processes
Bing Zhang, Zhun Lu, Bo-Qiang Ma +1
We extract the Boer-Mulders functions of valence and sea quarks in the proton from unpolarized Drell-Yan data measured by the FNAL E866 Collaboration. Using these Boer-Mulder…
Double transverse spin asymmetry in the Drell-Yan process from Sivers functions
Zhun Lu, Bo-Qiang Ma, Ivan Schmidt
We show that the transverse double spin asymmetry (DSA) in the Drell-Yan process contributed only from the Sivers functions can be picked out by the weighting function $\frac{Q_T}{…
Transverse spin effects of sea quarks in unpolarized nucleons
Zhun Lu, Bo-Qiang Ma, Ivan Schmidt
We calculate the non-zero Boer-Mulders functions of sea quarks inside the proton in a meson-baryon fluctuation model. The results show that the transverse spin effects of sea quark…
The cos 2 phi asymmetry of Drell-Yan and J/psi production in unpolarized ppbar scattering
Vincenzo Barone, Zhun Lu, Bo-Qiang Ma
We investigate the cos 2 phi azimuthal asymmetry in Drell--Yan and J/psi production from unpolarized ppbar scattering at GSI-HESR energies. The contribution to this asymmetry arisi…
