On the naturalness of the Froggatt-Nielsen mechanism as a solution to the flavor problem
Speaker: Roberto Mattacchione (Roma Sapienza Univ.) The fermion mass hierarchy remains one of the most glaring puzzles of the Standard Model (SM). A prominent framework to address this is the Froggatt-Nielsen (FN) mechanism, where hierarchical Yukawa couplings originate from a spontaneously broken flavor symmetry. In this setup, effective higher-dimensional operators generate fermion masses after heavy …
