Hi Gary. It occurs to me that the Higgs field is supposed to be a product of complex and quaternion fields, so perhaps the multiplication in your first equation is relevant there.
I have become comfortable with the idea of 3 temporal dimensions from working with Fourier analysis of plane waves, but your essay reveals another possibility - complex time. Quite an interesting idea. Had to chuckle at your comment about nature being devious, having asked myself that a few times.
But I have to question the hypothesis of an absolute speed relating to the Mp/Me ratio in the way you suggest. If the cosmic microwave background defines the rest frame, the speed of the solar system is about 0.0012c, which is about 1/5 the absolute speed, 0.006136c, required to produce the Mp/Me ratio. A practical researcher does not ignore hunches based on numerical coincidence, but sometimes that's all it is. In any case, failure of this final speculation would not affect the rest of the work.
By the way, I think I first read about three time dimensions in Milo Wolff's book about space resonance and matter waves which seems to reflect some aspects of the Higgs mechanism - the book with Milo (presumably) and his motorcycle on the cover. His tripod website is still there. Sad to hear of his passing.
Anyway, nice work! - cw
