What Happens to Entangled Particles During Collider Experiments?

I'm sure this idea has been considered since the invention of the particle accelerator. What would happen to an entangled particle if it's pair was collided in an accelerator? My guess is simply an end to entanglement but I'm too curious not to ask.

Entangled in which property?
Most collisions would break entanglement in most properties. And it is hard to find a property that survives the acceleration process before.

Was just thinking of the most classical measureable - spin. Also was wondering if this experiment was actually ever performed.

I doubt that you can accelerate a particle significantly without measuring its spin. An inelastic collision would certainly break entanglement.
What would you learn from the experiment?
