Measurement of $A_{LL}(pT)$ for single hadron photoproduction at high $p_T$ at COMPASS
In order to understand the gluon contribution to the nucleon spin, some experiments can study the production of hadrons at high transverse momemtum from lepton-nucleon or nucleon-nucleon scattering. RHIC has recently measured such double spin asymmetries A LL ( p T ) for pion production at high cent...
