Effective Field Theory of 3He

Effective Field Theory of 3He

We examine the effects of the long range Coulomb force on the three-body contact interaction in a pionless effective theory of 3 He. The corresponding interaction in 3 H exhibits limit-cycle behavior and we show that this is not altered by the 1/ r singularity of the potential.
