Contribution

It introduces the application of pseudospin symmetry in effective field theory for nuclear interactions, highlighting its benefits over conventional approaches.

Findings

Pseudospin symmetry is approximately conserved in nuclei.

Using pseudospin operators provides advantages in nucleon-nucleon interaction descriptions.

Abstract

Pseudopsin has been shown to be approximately conserved in nuclei. We investigate whether or not there is an advantage in using the pseudospin operators as well as the spin operators in the description of the nucleon-nucleon interaction. We conclude that, indeed, there is an advantage.
