Status of Trimaximal Neutrino Mixing

Abstract

Trimaximal mixing is the mixing hypothesis with maximal symmetry. In trimaximal mixing there remains a still worrying conflict between the large values of $\Delta m^2$ preferred by the atmospheric fits (possibly supported by the early K2K data) and reactor limits on ${\nu }_e$-mixing. However, the latest solar results do seem to point to energy-independent (ie. `no-scale') solar solutions, like the trimaximal solution.
