A Message from Kathleen Plinske, President, Osceola, Lake Nona, and Poinciana Campuses
Osceola Campus Professor of Physics Jay Pérez and four co-authors recently published a paper, titled “Stitching an asymmetric texture with T13 × Z5 family symmetry” in Physical Review D.
Jay provided this summary of the work:
The Standard Model of particle physics has now withstood all experimental challenges aimed at it, giving us our most accurate and comprehensive model of what nature is doing at the smallest of scales. Its elegance lies in organizing myriad particles and their interactions in terms of just a few elementary particles and a set of symmetries that determine how they can interact; given the charges of the elementary particles and the symmetries of the basic laws, the possible interactions between these particles become fixed.
Unfortunately (or fortunately!), however, the Standard Model still leaves us with many mysteries, one of which is why nature seems to repeat itself: each particle in a “family” with two identical copies differs only by its mass. Here again symmetries can play an important role, allowing us to restrict the possible interactions between family members and pointing the way to a more fundamental theory. My collaborators and I recently proposed such a model with a novel symmetry based on the arithmetic of a finite number system with only 13 numbers, T13.
