On several levels of theoretical physics,especially particle physics and early universe cosmology,de Sitter space-time has become an attractive possibility.The
We investigate the extinction coefficients of the surface atmospheric aerosol over the Large High Altitude Air Shower Observatory (LHAASO), located at the Haizi
The precise determination of neutron distribution has important implications for both nuclear structure and nuclear astrophysics. The purpose of this paper is t
We make use of Manton's analytical method to investigate the force between kinks and anti-kinks at large distances in 1+1 dimensional field theory.The relat
