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).
