Just to jump in with a quick comment...
I'm not convinced we
can detect any dimensions beyond ours.
Could a two-dimensionsal creature detect a third dimension? How, as it "doesn't exist except as a mathematical construct" in his/her/its realm? That doesn't mean it cannot exist, only that it cannot be detected. (Take a cube. Limit yourself to measuring width and length only, and tell me how you measure the cube's height except as a mathematical construct.)
Logically, furthermore, 0, 1, and 2 dimensions
must exist because our realm has them, even if we are not able to detect their particles directly. (The cube exists in our realm. We can measure length, width and height, so they must exist; the third dimension is composed of the previous dimensions plus one.)
So far as electrons being 3 or something else dimensional, would it be possible for a 0, 1 or 2 dimensional particle to interact with a 3 dimensional one? (Open question, all responses appreciated.)
