摘要：
We calculate the single transverse spin asymmetries (SSA) for forward inclusive particle production in pp and pA collisions using a hybrid approach. It is shown that the Sivers type contribution to the SSA drops out due to the color entanglement effect, whereas the fragmentation contribution to the spin asymmetry is not affected by the color entanglement effect. This finding offers a natural solution for the sign mismatch problem.
