Uncovering Hidden Leptonic Correlations with Flow Matching and Autoencoders

Haruto Kitagawa, Satsuki Nishimura, Hajime Otsuka

We perform a global search for values of the Yukawa matrices and Majorana masses in the Type-I seesaw mechanism. Using flow matching, which is a generative artificial intelligence…
