Multifarious roles of hidden chiral-scale symmetry: “quenching” ga in nuclei

HIGHLIGHTS

• who: Mannque Rho from the Institut de Physique Théorique, Université Paris-Saclay, CNRS, CEA, Gif-sur-Yvette, France have published the article: Multifarious Roles of Hidden Chiral-Scale Symmetry: ``Quenching'' gA in Nuclei, in the Journal: Symmetry 2021, 13, 1388. of /2021/

SUMMARY

The coupling constant g A appearing in the nucleonic axial current used to calculate nuclear Gamow-Teller matrix elements is in fact not quenched in the sense used in shell-model calculations in the literature. As emphasized there, given the superallowed transition with zero momentum transfer, the quantity M . . .
