New Opportunities for the Study of Baryon Number Violation at Low-Energy Accelerators

Abstract

I motivate new searches for baryon-number violation and consider, particularly, the prospects for detecting baryon number violation by two units at low-energy accelerators with intense electron beams, using ARIEL as a particular example.

“…Moreover, baryon number violation in the SM, although technically allowed, can only occur in the non-perturbative regime of the electroweak theory and is only expected to occur at exceptionally high temperatures, being thus unobservable today. Indeed, BNV has long been considered [3] one of the fundamental conditions to explain the observed baryon asymmetry of the Universe (BAU) and might be the key link between dark matter and ordinary baryonic matter, e.g, if baryon number is apparently violated, but conserved across dark and visible sectors [5,6].…”
