We attempt to explain the large ${\bar \Lambda}/\bar p$ ratios measured in heavy ion collisions at $12~{\rm A\cdot GeV}/c$ beam momentum within an hadronic framework. The ratios are large compared to corresponding ratios in $pp$ collisions,…
The possibility is examined for the inclusive $\Lambda$ in unpolarized electron-positron annihilation to be transversely polarized. Due to final-state interactions, there exists a novel structure function $\hat F(z,Q^2)$ for the inclusive…
Parton distribution functions are key quantities for us to understand the hadronic structures in high-energy scattering, but they are difficult to calculate from lattice QCD. Recent years have seen fast development of the large-momentum…
