The parameters of separable coupled channels s-wave potentials for the strong
KN interaction are determined from low energy K⁻p scattering data with
additional constraints from π⁻p π∑K° production data. The shifts and
widths of the Coulomb bound states in kaonic hydrogen are calculated with
these potentials and compared with experiment....
Optical potential for antikaon-nucleus strong interactions are constructed using
elementary antikaon-nucleus potentials determined previously. The optical potentials
are used to determine the existence of a kaon hypernucleus. Modern three
dimensional visualization techniques are used to study model dependences, new
methods for speeding the calculation of the optical potential are developed,...
The microscopic, momentum space, optical potential description of spin 1/2 x 1/2 scattering is extended to include the coupling of the singlet-triplet spin channels and
the exact handling of the Coulomb force. Computing performance in constructing
the optical potential and in solving the coupled-channels Lippmann-Schwinger equations
is enhanced by parallelization...
We study the four-quark interaction as a first step in understanding the
QCD origin of the nuclear force in nature. We simulate QCD on a 20 x 20 x 20 x 32
space-time lattice with the simplifying quenched and static approximations, and
with the SU(2) gauge group. Recent four-quark simulations...
Classical chaotic scattering experiments were performed on ten different four hill potentials, unique under x-axis reflection, given by: V(x,y) = x²y²e⁻⁽ˣ² ⁺ ʸ²⁾ σᵢ where σᵢ was ±1 depending upon quadrant. Our work was based on a paper (9) that only studied the case where σᵢ =1 in all quadrants....
ThermoSolver is an educational thermodynamics software program designed to be both
easy to use and useful in that it permits the user to make nontrivial chemical engineering
thermodynamic calculations. The software program accompanies the textbook
Engineering and Chemical Thermodynamics by Milo Koretsky, and is available for free
download from the...
