Comment 15 by Alex, adv. diab. The Standard Model has new, more extensive symmetries which are necessary to describe weak interactions, and these symmetries suddenly forbid things that were allowed in the subset of the theory which didn't have those symmetries.

... And yet particle decay depends on symmetry VIOLATION by the weak interaction. Aren't you standing things on their heads here, because it is the very LACK of complete symmetry that allows particle decays that would otherwise be forbidden: Stanford.edu article

There are a number of conservation laws that are valid for strong and electromagnetic interactions, but broken by weak processes. So, despite their slow rate and short range, weak interactions play a crucial role in the make-up of the world we observe.

Note the word, "broken", which presumably applies in the absence of supersymmetry theory, which allows for your "hiding" as opposed to "breaking".

You still have to explain the asymmetry of supersymmetry w/r to particle masses.
