Parametrizations of the Seesaw or can the Seesaw BE Tested?
Abstract
This proceedings contains a review, followed by a more speculative discussion. I review different coordinate choices on the 21-dimensional parameter space of the seesaw, and which of these 21 quantities are observable. In MSUGRA, there is a 1-1 correspondance between the parameters, and the interactions of light (s)particles. However, not all of the 21 can be extracted from data, so the answer to the title question is "no". How to parametrise the remaining unknowns is confusing--different choices seem to give contradictory results (for instance, to the question "does the Baryon Asymmetry depend on the CHOOZ angle?"). I speculate on possible resolutions of the puzzle.
