Hadron Collider Tests of Neutrino Mass-Generating Mechanisms

Understand

The Standard Model of particle physics (SM) is presently the best description of nature at small distances and high energies.

• However, with tiny but nonzero neutrino masses, a Higgs boson mass unstable under radiative corrections, and little guidance on understanding the hierarchy of fermion masses, the SM remains an unsatisfactory description of nature.
• Well-motivated scenarios that resolve these issues exist but also predict extended gauge (e.g., Left-Right Symmetric Models), scalar (e.g., Supersymmetry), and/or fermion sectors (e.g., Seesaw Models).
• Hence, discovering such new states would have far-reaching implications.
