On the status of the superconducting order in Sr₂RuO₄

_{The long-standing quest to determine the superconducting order in Sr2RuO4 has received renewed attention after recent nuclear magnetic resonance (NMR) experiments have cast doubt on the possibility of spin-triplet pairing in the superconducting state. In this talk I will give an overview of recent developments in the field, with a focus on how new experimental evidence compare with and constrain three possible theoretical scenarios for the superconducting order parameter.}
