Restructuring and the Enterprise
No full textWhether restructuring becomes a deep socioeconomic and political reform or just one more superficial administrative reorganization depends primarily on the degree to which there is substantive change in the enterprise's status in the economic mechanism. We understand the economic mechanism to mean the regulatory subsystem of the economic system that incorporates state management of the national economy, production self-management of enterprises, and in part the spontaneous regulation of economic relations.

Electromagnetic interactions and oscillations of ultrahigh-energy cosmic neutrinos in interstellar space
No full textWe present a theoretical analysis [1] of possible influence of neutrino magnetic moments on the propagation of ultrahigh-energy cosmic neutrinos in the interstellar space under the assumption of two-neutrino mixing. The exact solution of the effective equation for neutrino evolution in the presence of a magnetic field and matter is obtained, which accounts for four neutrino species corresponding to two different flavor states with positive and negative helicities. Using most stringent astrophysical bounds on the putative neutrino magnetic moment, probabilities of neutrino flavor and spin oscillations are calculated on the basis of the obtained exact solution. Specific neutrino-oscillation patterns are determined for neutrino-energy values characteristic of, respectively, the cosmogenic neutrinos, the Greisen-Zatsepin-Kuz’min cutoff, and well above the cutoff.

Study of the p–p–K + and p–p–K - dynamics using the femtoscopy technique
No full textThe interactions of kaons (K) and antikaons (K ̄) with few nucleons (N) were studied so far using kaonic atom data and measurements of kaon production and interaction yields in nuclei. Some details of the three-body KNN and K ̄ NN dynamics are still not well understood, mainly due to the overlap with multi-nucleon interactions in nuclei. An alternative method to probe the dynamics of three-body systems with kaons is to study the final state interaction within triplet of particles emitted in pp collisions at the Large Hadron Collider, which are free from effects due to the presence of bound nucleons. This Letter reports the first femtoscopic study of p–p–K + and p–p–K - correlations measured in high-multiplicity pp collisions at s = 13 TeV by the ALICE Collaboration. The analysis shows that the measured p–p–K + and p–p–K - correlation functions can be interpreted in terms of pairwise interactions in the triplets, indicating that the dynamics of such systems is dominated by the two-body interactions without significant contributions from three-body effects or bound states
