Fig. 4: Constraints on the Jarlskog invariant.
From: Joint neutrino oscillation analysis from the T2K and NOvA experiments
a–d, Marginalized posterior probabilities of the Jarlskog invariant, JCP, in the case of the normal (blue; a,b) and inverted (orange; c,d) neutrino mass ordering with the reactor constraint applied. The posterior distributions use prior distributions either flat in δCP (a,c) or sin δCP (b,d). Shaded areas show the 1σ, 2σ and 3σ Bayesian credible intervals.
