Information entropy of nuclear electromagnetic transitions in AdS/QCD

Abstract

Electromagnetic transitions involving nucleons and their resonances are here presented in the fermionic sector of the AdS/QCD soft-wall model, using the differential configurational entropy (DCE) as a measure of information entropy. The DCE is employed to derive adjustable parameters that define the minimal and nonminimal couplings in the nuclear interaction with a gauge vector field, in the nucleonic $\gamma N\to N^{\ast }(1535)$ transition. The values obtained comply with phenomenological data with good accuracy.
