Interparticle

Description
An interparticle is a particle that can interact with particles of different laws of physics due to the fact that it shares one or more properties that exist in the participating particles' laws of physics.

Examples
In a universe where the concept of mass is non-existent and thus no particles in that universe would have a mass property. It would therefore be impossible for these particles to be influenced by the gravitational force in our universe. In order for particles of separate laws of physics to interact with particles of our universe, they must share at least one property for which forces can be transferred to-and-from. An example would be a particle which permits the interaction of xenoparticles with existons from our universe.
