Onset of $\eta$ nuclear binding

Abstract

Recent studies of $\eta$ nuclear quasibound states by the Jerusalem-Prague Collaboration are reviewed, focusing on stochastic variational method self consistent calculations of $\eta$ few-nucleon systems. These calculations suggest that a minimum value Re$a_{\eta N}\approx 1$ fm (0.7 fm) is needed to bind $\eta {}^3$He ($\eta {}^4$He).
