A common source for neutrino and sparticle masses
Andrea Brignole, Filipe R. Joaquim, Anna Rossi
TL;DR
This paper explores supersymmetric models where neutrino and sparticle masses originate from effective operators in the Kahler potential, proposing a scenario linking seesaw mediators with SUSY-breaking messengers.
Contribution
It introduces explicit realizations of Kahler operators in the type II seesaw framework and connects seesaw mediators with SUSY-breaking messengers.
Findings
Neutrino masses can arise from d=6 Kahler operators in SUSY models.
Seesaw mediators can be identified with SUSY-breaking messengers.
The proposed scenario offers a unified mechanism for neutrino and sparticle mass generation.
Abstract
We discuss supersymmetric scenarios in which neutrino masses arise from effective d=6 operators in the Kahler potential (including SUSY-breaking insertions). Simple explicit realizations of those Kahler operators are presented in the context of the type II seesaw. An appealing scenario emerges upon identifying the seesaw mediators with SUSY-breaking messengers.
