Webb30 aug. 2024 · The formulation of a pionless EFT has been employed to calculate the cross-section and thermonuclear reaction rate of the \(^{3}\text{He}(\alpha ,\gamma )^{7}\text{Be}\) radiative capture reaction in the low energy region. As explained in our last works, we assumed \(^{3}\text{He}\) as a two-body structure consisting of deuteron and … Webb10 apr. 2024 · Over the past few decades, a number of studies have also been performed in pionless EFT, which uses nucleons as the only dynamical degrees of freedom [15–20]. At energies relevant for astrophysics, the process lies well within the …
Webbdescription in the pionless EFT might indicate that the theory can be useful in studying larger nuclei. Since the pionless EFT makes no use of the QCD chiral symmetry, it cannot directly predict the quark mass dependence of observables. The parameters of the pionless EFT, at the lowest orders in the low-energy expansion, are the threshold ...
