In this case, using a Particle Groups operator is the most efficient way.
If you want Event A to send out when colliding with Event B, set particles groups in event A to [1] and particle groups in event B to [1,2] (overlapping, so they collide with each other, but different so they can be differentiated in the test).
Then in your PhysX Collision operator in Event A, set the group condition to [equals 1,2]...that way the test condition will be met only when a particle in A collides with a particle in B.
