We evaluate the β-decay rates within the gross theory of beta decay (GTBD) and compare the results for different values of the axial-vector coupling constant, gA = 0.76, gA = 0.88, gA = 1, gA = 1.13, and gA = 1.26, and also different energy distribu

Systematic approach to β and 2vββ decays of mass A=100-136 nuclei

Autor: Pirinen, Pekka, Suhonen, Jouni

In this work we perform a systematic study of pairs of single-β-decaying nuclei in the mass region A = 100–136 to extract information on the effective value of the axial-vector coupling constant gA. As the many-body framework we use the quasiparti

Single and double beta decays in the A=100, A=116 and A=128 triplets of isobars

Autor: Suhonen, Jouni, Civitarese, Enrique Osvaldo

In this paper we analyze the ground-state-to-ground-state two-neutrino double beta (2νββ) decays and single EC and β− decays for the A=100 (100Mo–100Tc–100Ru), A=116 (116Cd–116In–116Sn) and A=128 (128Te–128I–128Xe) triplets of isoba

Ground-state-to-ground-state two-neutrino double beta (2νββ) decays and single beta (EC and β−) decays are studied for the A=100 (100Mo100Tc100Ru), A=116 (116Cd116In116Sn) and A=128 (128Te128I128Xe) nuclear systems by using the proton–neutron

The nucleon axial-vector coupling beyond one loop

Autor: Véronique Bernard, Ulf-G. Meißner

Publikováno v: Physics letters / B 639, 278-282 (2006). doi:10.1016/j.physletb.2006.06.018

We analyze the nucleon axial-vector coupling to two loops in chiral perturbation theory. We show that chiral extrapolations based on this representation require lattice data with pion masses below 300 MeV.

Proširen model kiralnih kvarkova potaknut Tamm-Dancoffovim približenjem

Publikováno v: Fizika B : a journal of experimental and theoretical physics

Fizika B

A procedure inspired by the Tamm-Dancoff method is applied to the chiral quark model which has been extended to include additional degrees of freedom: a pseudoscalar isoscalar field as well as a triplet of scalar isovector fields. The simpler, generi
