Three-body breakup within the fully discretized Faddeev equations

A novel approach is developed to find the three-body breakup amplitudes and cross sections within the modified Faddeev equation framework. The method is based on the lattice-like discretization of the three-body continuum with a three-body stationary wave-packet basis in momentum space. The approach makes it possible to simplify drastically all the three- and few-body breakup calculations due to discrete wave-packet representations for the few-body continuum and simultaneous lattice representation for all the scattering operators entering the integral equation kernels. As a result, the few-body breakup can be treated as a particular case of multi-channel scattering in which part of the channels represents the true few-body continuum states. As an illustration for the novel approach, an accurate calculations for the three-body breakup process $n+d\to n+n+p$ with non-local and local $NN$ interactions are calculated. The results obtained reproduce nicely the benchmark calculation results using the traditional Faddeev scheme which requires much more tedious and time-consuming calculations.Comment: 17 pages, 13 figure

Evaluating the effectiveness of public health financing based on financial and non-financial indicators in terms of the knowledge economy

In conditions of the knowledge economy human capital, human value are the main factors of economic growth and prosperity of the state. Qualitative characteristics of human capital are indicators of public health. Therefore, one of the most important tasks of the state is to assess the effectiveness of financing public health expenditures. The methodological base of the research was the methods of system and economic analysis, mathematical statistics and decision optimization, which resulted in the identification of factors influencing the resource supply, availability and quality of public health. The formation of a comprehensive indicator of the effectiveness of the public health system based on the system of financial and non-financial indicators will allow to form numerically an assessment of the effectiveness of investments in public health and draw conclusions about the resources' provision, level of development, accessibility and quality of public health. The obtained results can be used in making effective public financial decisions, which allow to achieve an increase of accessibility and quality of health care, focusing on the human capital in conditions of knowledge economy.peer-reviewe

Nature of S\bm{S}-wave NN\bm{NN} interaction and dibaryon production at nucleonic resonance thresholds

Phase shifts and inelasticity parameters for $NN$ scattering in the partial-wave channels ${}^3S_1$--${}^3D_1$ and ${}^1S_0$ at energies $T_{\rm lab}$ from zero to about 1 GeV are described within a unified $NN$ potential model assuming the formation of isoscalar and isovector dibaryon resonances near the $NN^*(1440)$ threshold. Evidence for these near-threshold resonances is actually found in the recent WASA experiments on single- and double-pion production in $NN$ collisions. There, the excitation of the Roper resonance $N^*(1440)$ exhibits a structure in the energy dependence of the total cross section, which corresponds to the formation of dibaryon states with $I(J^\pi)=0(1^+)$ and $1(0^+)$ at the $NN^*(1440)$ threshold. These two $S$-wave dibaryon resonances may provide a new insight into the nature of the strong $NN$ interaction at low and intermediate energies.Comment: 10 pages, 8 figure
