Nuclei are unique analyzers of the space-time development of jets at early stage. We argue that the gluon bremsstrahlung, rather than the color string, is the main mechanism of hadronization of highly virtual quarks produced in a hard interaction. It results in an energyand time-independent density of energy loss, like a color string, but steeply dependent on the quark virtuality. Effects of fo...
The possibility for occurrence of a Bose condensate of dibaryons in nuclear matter is investigated within the framework of the Walecka model in the mean-field approximation. Constraints for the ωand σ-meson coupling constants with dibaryons following from the requirement of stability of dibaryon matter against compression are derived and the effect of σand π-meson exchange current contributions...
We present a method to calculate nuclear matter properties in the superfluid phase. The method is based on the use of self-consistent off-shell nucleon propagators in the T-matrix equation. Such a complete treatment of the spectral function, is required below and around Tc due to a pseudogap formation in the spectral function. In the superfluid phase we introduce the anomalous self-energy in th...
The first who reported [1-3] Palladium catalysed fusion of hydrogen nuclei to Helium at room temperature were German researchers Paneth and Peters in 1926. They retracted their work for unknown reasons. Lochte-Holtgreven studied LENR in the 1970s and reported [4-5] neutrons when electrically exploding deuterated liquids. He was director of the institute for experimental physics at the Christian...
The kaon energy in a nuclear medium and its dependence on kaonnucleon and nucleon-nucleon correlations is discussed. The transition from the Lenz potential at low densities to the Hartree potential at high densities can be calculated analytically by making a Wigner-Seitz cell approximation and employing a square well potential. As the Hartree potential is less attractive than the Lenz one, kaon...
Soil organic matter is the largest source of organic carbon in the soil surface which played an enormous role in restoring balance, environmental sustainability, soil elements and climatic conditions. Organic materials influence physical, chemical and biological properties of soil and thus soil fertility directly and indirectly. The amount, type and composition of organic matter are different i...
The universe contains a remarkably wide variety of atomic nuclei, with mass numbers A (the sum of the numbers of proton Z and the neutron N) up to 250. While there are many interesting properties details that differentiate these nuclei from each other, there is also a powerful set of systematic trends and general properties that provide an important and useful framework for understanding the ba...
