ΛΛ6He in cluster effective field theory

ΛΛ6He in cluster effective field theory

The bound state of ΛΛ6He is studied as a three-body (ΛΛα) system in a cluster effective field theory at leading order. We find that the system exhibits the limit cycle that is associated with the formation of bound states called the Efimov states. This implies that the three-body contact interaction...
