摘要
In light of a new experiment which claims a positive identification, we discuss the possible existence of the tetraneutron. We explore a model based on a dineutron-dineutron molecule. We show that this model is not able to explain the tetraneutron as a bound state, in agreement with other theoretical models already discussed in the literature.
