Abstract：
One and two-gluon exchange potentials (OGEP and TGEP) relevant to the pp→ΛΛ transition process are derived from the S-matrix in the a　roximation of order p²/m². An effective transition potential obtained from these gluon exchange potentials by the constituent quark model is employed to calculate the differential and total cross-sections for the pp→ΛΛ reaction in the plane wave Born Approximation.The calculated result shows that the relativistic correction terms in the OGEP and TGEP give considerable improvements on the cross-section in comparison with the previous calculations performed by making use of the OGEP given in the extremely non-relativistic a　roximation.
