Affleck-Dine Leptogenesis with One Loop Neutrino Mass and strong CP

We present a unified model that solves four major problems of the standard model i.e. neutrino masses, the origin of matter, strong CP problem, and dark matter using the framework of the Affleck-Dine (AD) mechanism. The AD field is responsible for inflation, the origin of matter, and neutrino masses which arise at the one-loop level. Neutrino masses are therefore intimately connected to the baryon to photon ratio of the universe. The dark matter in the model is the axion field used to solve the strong CP problem. The model has a near massless Majorana fermion which contributes to ΔNeff∼0.1 in the early universe, which can be tested in the upcoming CMB-S4 experiment.
