Uncertainties in nuclear transition matrix elements for neutrinolessββdecay

CKM Matrix Elements : Magnitudes , Phases , Uncertainties 1 Jonathan

Schemes for fermion masses should predict elements of the Cabibbo-KobayashiMaskawa (CKM) matrix. We review the freedom allowed by present experiments and how the parameter space will shrink in the next few years. In addition to experiments which directly affect CKM parameters, we discuss constraints arising from precise electroweak tests.

Nuclear G-Matrix Elements from Nonlocal Potentials

We study effects of nonlocality in the nuclear force on the G-matrix elements for finite nuclei. Nuclear G-matrix elements for 16O are calculated in the harmonic oscillator basis from a nonlocal potential which models quark exchange effects between two nucleons. We employ a simple form of potential that gives the same phase shifts as a realistic local nucleon potential. The G-matrix elements ca...
