Comment on 'Photoproduction of $η$--Mesic ${^3}$He'
Abstract
Description
In a recent paper by the TAPS collaboration \cite{exp} a first measurement of a bound system of an $η$ meson and a ${^3}$He nucleus was reported. In this comment we critically reexamine the interpretation of the data and show that the data prefers a solution where there is no bound state present. Given the low statistics of the measurement, however, it does not exclude the existence of a bound state.
