Temperature of Cosmological Constant

[friend]

Is there a temperature related to the cosmological constant?

As I understand it, the cosmological constant is produced by dark energy and is a form of zero point energy created by virtual particles and antiparticles being created and annihilated all the time. It seems to me that this process could produce a temperature that might be measureable. With particles pairs being created and annihilated everywhere at all times, it seems likely that a virtual particle created somewhere might collide with another virtual particle created nearby and prevent some virtual particles from annihilating with the partener it was created with. The net result would be creation of real particles creating a background radiation which we might be able to measure. Or do all such virtual pairs travel right through each other like bosons?

The idea of using virtual particles to predict the cosmological constant suffers from one fatal flaw - the size predicted is about 120 orders of magnitude too large.

I guess I'm asking if separate virtual particle pairs can interact with each other and produce real particles.

The only theory (I know of - I'm no expert) that seems like your suggestion is black hole evaporation, where one of the pair escapes and the other is absorbed in the black hole.
