Bridging resonant leptogenesis and low-energy CP violation with an RGE-modified seesaw relation

We propose a special type-I seesaw scenario in which the Yukawa coupling matrix $Y_{\nu }^{}$ can be fully reconstructed by using the light Majorana neutrino masses $m_i^{}$, the heavy Majorana neutrino masses $M_i^{}$ and the PMNS lepton flavor mixing matrix $U$. It is the RGE-induced correction to the seesaw relation that helps interpret the observed baryon-antibaryon asymmetry of the Universe via flavored resonant thermal leptogenesis with $M^{}_1 \simeq M^{}_2 \ll M^{}_3$\mathrm{.}Weshowthatourideaworkswellineitherthe$\tau$-flavoredregimewithequilibriumtemperature$T \simeq M^{}_1 \in (10^9, 10^{12}]$GeVorthe$(\mu+\tau)$-flavoredregimewith$T \simeq M^{}_1 \in (10^5, 10^9]$ GeV, provided the light neutrinos have a normal mass ordering. We find that the same idea is also viable for a {\it minimal} type-I seesaw model with two nearly degenerate heavy Majorana neutrinos.
