Single-particle energies of Λ and Σ hyperons in several nuclei are obtained from the relevant self–energies. The latter are constructed within the framework of a perturbative many-body approach employing present realistic hyperon-nucleon interactions such as the models of the Jülich and Nijmegen groups. The effects of the non-locality and energy-dependence of the self– energy on the bound state...

As a result of advanced digital technology, we have become increasingly reliant on global connectivity device such as laptops, tablets, and mobile phones. So, the interaction human eyes with industrial light devices becomes full dangers caused by short distance long duration view. With specific details, this study discusses supports physics light-eye interaction. The physical treatment shows th...

the r+(=E s+) mesons. On the other hand, analyses' of the decay products of r+ strongly suggest on the grounds of angular momentum and parity conservation that the ~+ and 8 are not the same particle. This poses a rather puzzling situation that has been extensively discussed. ' One way out of the difhculty is to assume that parity is not strictly conserved, so that 0+ and v-+ are two diGerent de...

The cross section for the proton weak capture reaction H(p,eνe) H is calculated with wave functions obtained from a number of modern, realistic high-precision interactions. To minimize the uncertainty in the axial two-body current operator, its matrix element has been adjusted to reproduce the measured Gamow-Teller matrix element of tritium β decay in model calculations using trinucleon wave fu...

These lectures are concerned with the structure of hadrons at low energies, where the strong coupling constant is large. Most of the hadronic world discussed here will be made up of the light u, d and s quarks since these are the constituents of the low-lying hadrons. The best way to gain information about the strongly interacting particles is thus the use of well-understood probes, such as the...

We have calculated the free energy of the crystal-melt interface for the Lennard-Jones system as a function of crystal orientation, near zero pressure, by examining the roughness of the interface using molecular dynamic simulations. The anisotropy is weak, but can be accurately resolved using this approach due to the sensitivity of the fluctuations on the anisotropy. We find that the anisotropy...
