Up to now we have developed the theory of the weak nuclear interaction at the level of the quarks, that is to say, of the constituents of the hadrons. In order to describe the weak interactions of the hadrons themselves we must in addition know how the hadrons are made up of quarks,...
beta decay- radioactive decay of an atomic nucleus that is accompanied by the emission of a beta particle radioactive decay,disintegration,decay- the spontaneous disintegration of a radioactive substance along with the emission of ionizing radiation ...
In medium and heavy nuclei both the number of levels that can be directly populated by the β decay is large and the number of levels available to which they can γ decay is also large. As a result, in general, individual γ - rays (emitted by levels at high excitation energy) have ...
In general, several contributions to the total \beta \beta 0\nu amplitude can add coherently, allowing for interference effects. Neutrinoless double-beta decay observables alone may be able to identify the dominant mechanism responsible for \beta \beta 0\nu . We give three examples. First, if...
The general conclusion is that, within a factor of 2-3 (i.e., of the same order of the present NME discrepancies), the decay rate per unit (isotope) mass does not depend on the nucleus or, equivalently, that there are no especially favored or disfavored isotopes. This also means that...
decay is generated only by the left-handed charged current weak interaction through the exchange of virtual light massive Majorana neutrinos, the probability amplitude of this process is proportional to the “effective Majorana mass parameter”: ||≡ |U e1 | 2 m 1 + |U e2 | 2 e iα21...
Beta Decay:Beta decay is a type of radioactive decay process where a parent nucleus emits an electron. Some neutron in the parent nucleus can split into an electron and a neutron. Once the parent nucleus emits the electron, there will then be an additional pro...
dominance of the tensor contribution in a general framework for neutrino me- diated double beta decay has been proven. In the present letter we reanalyze SUSY–accompanied double beta decay and discuss the relative importance of the different nuclear matrix elements involved. The mixing between ...
On the basis of a previous analysis of hyperon semileptonic decay data, a prediction is presented for g(1)/f(1) in the Xi(0) --> Sigma(+) e(nu)over-bar beta-decay. The analysis takes into account SU(3) breaking in this sector via the inclusion of mass-driven corrections. A rath...
The Monument experiment measures ordinary muon capture (OMC) on isotopes relevant for neutrinoless double-beta ( $$0\nu \beta \beta $$ ) decay and nuclear
