What is the smallest portion of energy?

What is the smallest portion of energy known so far? Could it be found within microwave background or amoung neutrinos?
Thanks!

0. And that's pretty exact.

Cheers,
Jazz

That's surely is, but is 0 SOME energy? In avoidance of math-phys-philo discusse on this mater, what has the second smallest energy already to known?

It's the same as the second smallest difference between two real numbers.

Ok. What posses the lowest energy already detected?

It's arbitrary, since in some frame it can be made as small as you want.

Yes, as E=hf where f can -> 1/inf, it might be. But what particle has been yet measured with the lowest known energy and what "particle" is suppossed to be?
