Özet
The imaginary part of the matrix element for associative charm particle photoproduction, gamma+N-->Lambda(c)+(D) over bar, has a definite spin structure, near the reaction threshold, being characterized by a single parameter. This allows us to predict, in the framework of an effective Lagrangian approach, the energy and the angular dependence of T-odd polarization observables such as the analyzing power in the reaction gamma+(p) over bar-->Lambda(c) + (D) over bar and the polarization of the Lambda(c) hyperon, produced in the collision of unpolarized particles. We find sizable values for these observables, which can be measured experimentally.
