Abstract

To test the model of the polarized gluon distribution ΔG(x, Q²) in the proton, we propose a new process, diffractive Λ_c⁺ productions in polarized pp reactions, which will be observed in the forthcoming RHIC and also the proposed HERA- \rm N experiments. The spin correlation between the target proton and the Λ_c⁺ produced in the target fragmentation region largely depends on ΔG(x, Q²) and thus, the process is quite promising for testing the models of ΔG(x, Q²).
