Fourier shape parameterization in covariant density functional theory for nuclear fission

Physics Letters B
We implement the Fourier shape parameterization within the point-coupling covariant density functional theory to construct the collective space, potential energy surface (PES), and mass tensor, which serve as inputs for the time-dependent generator ...

Discrepancies in Atomic Data and Suggestions for Their Resolutions [PDF]

Atoms, 2017
The analysis and modelling of a range of plasmas (for example, astrophysical, laser- produced and fusion) require atomic data for a number of parameters, such as energy levels, radiative rates and electron impact excitation rates, or equivalently, the effective collision strengths. Such data are desired for a wide range of elements and their many ions,

Prospect for measurement of the CP-violating phase  $$\phi _s$$ ϕ s in the $$B_{s}\rightarrow J/\psi \phi $$ B s → J / ψ ϕ channel at a future Z factory

European Physical Journal C: Particles and Fields
The CP-violating phase $$\phi _s$$ ϕ s , the $$B_{s}$$ B s decay width ( $$\varGamma _s$$ Γ s ), and the $$B_{s}$$ B s decay width difference ( $$\varDelta \varGamma _s$$ Δ Γ s ) are sensitive probes to new physics and can constrain the heavy quark ...
