13. Description of particle-antiparticle bound systems via numerical solutions of the Dirac-Coulomb equation

Prof. Theocharis Kosmas (University of Ioannina)

02/07/2024, 09:30

In this talk we discuss binary particle-antiparticle atomic systems starting from the formulation (in $16\times 16$ matrix form) of the relevant 2-body Dirac-Coulomb Hamiltonian. Then, we apply the separation of the radial dependence from the angular-spin dependence of the Dirac-spinor components based on the conservation laws that must be full filled as: the well-defined charge-conjugation,...

7. Introducing SPADES

Dr Stefan-Alexandru Ghinescu (CIFRA)

SPADES (Spectra and Phase spAce factors in Double bEta decayS), a software package for theoretical double beta decay analysis, integrates RADIAL package and the DHFS method to compute electron wave functions accurately in complex atomic systems. Its user-friendly interface facilitates input of parameters for seamless computations. Researchers can compare spectra and phase space factors across...

15. Neutrinoless double-beta decay investigations of 82Se using three shell model Hamiltonians

Andrei Neacsu (CIFRA)

Recent studies of neutrinoless double-beta decay matrix elements have employed statistical approaches based on modified shell model effective Hamiltonians for 48Ca (Phys. Rev. C 106, 054302 (2022)) and 136Xe (Phys. Rev. C 107, 045501 (2023)). The analyses rely on inducing perturbations in the starting effective Hamiltonians to observe the behavior of a wide range of observables, besides the...
