Beam single spin asymmetry of neutral pion production in semi-inclusive deep inelastic scattering

Wenjuan Mao, Zhun Lu

We study the beam spin asymmetry $A_{LU}^{\sin {\varphi }_h}$ in semi-inclusive ${\pi }^0$ electroproduction contributed by the T-odd twist-3 distribution function $g^{\perp }(x,k_T^2)$. We calculat…
