COMPUTER MODELLING OF HEAT EXTENSION IN A DETAIL IN THE COMBINED PROCESS OF PLASMA SPRAYING AND STRENGTHENING OF PLASMA COATING Компьютерное моделирование распространения тепла в детали в комбинированном процессе плазменного напыления и упрочнения покрытия

Abstract: The modeling method of heat extension in a detail in the combined process of plasma spraying coating with electromechanical treating and cooling by water jet is worked out. It is shown, that water cooling essentially decreases detail surface temperature and forms more strong coating thank to reduction of inner strains in the coating
Masses and couplings of vector mesons from the pion electromagnetic, weak, and πγtransition form factors
D. Melikhov,O. Nachtmann,V. Nikonov,T. Paulus
Physics , 2003, DOI: 10.1140/epjc/s2004-01726-4
Abstract: We analyse the pion electromagnetic, charged-current, and $\pi\gamma$ transition form factors at timelike momentum transfers $q$, $q^2=s\le 1.4$ GeV$^2$, using a dispersion approach. We discuss in detail the propagator matrix of the photon-vector-meson system and define certain reduced amplitudes, or vertex functions, describing the coupling of this system to final states. We then apply the derived analytic expressions to the analysis of the recent $e^+e^-\to \pi^+\pi^-$, $\tau^-\to \pi^-\pi^0\nu_\tau$, and $e^+e^-\to \pi^0\gamma$ data. We find the reduced amplitudes for the coupling of the photon and vector mesons to two pseudoscalars to be constant, independent of $s$, in the range considered, indicating a "freezing" of the amplitudes for $s\le 1$ GeV. The fit to the form factor data leads to the following values of the Breit-Wigner resonance masses m_{\rho^-}=775.3\pm 0.8 MeV, m_{\rho^0}=773.7\pm 0.6 MeV and m_\omega=782.43\pm 0.05 MeV, where the errors are only statistical.

Photoproduction of Baryons Decaying into N pi and N eta
A. V. Anisovich,A. Sarantsev,O. Bartholomy,E. Klempt,V. A. Nikonov,U. Thoma
Physics , 2005, DOI: 10.1140/epja/i2005-10120-5
Abstract: A combined analysis of photoproduction data on \gamma p to \pi N, eta N was performed including the data on K Lambda and K Sigma. The data are interpreted in an isobar model with s--channel baryon resonances and pi, rho,(omega), K, and K^* exchange in the t--channel. Three baryon resonances have a substantial coupling to eta N, the well known N(1535)S_{11}, N(1720)P_{13}, and N(2070)D_{15}. The inclusion of data with open strangeness reveals the presence of further new resonances, N(1840)P_{11}, N(1875)D_{13} and N(2170)D_{13}.
The study of the proton-proton collisions at the beam momentum 1628 MeV/c
K. N. Ermakov,V. I. Medvedev,V. A. Nikonov,O. V. Rogachevsky,A. V. Sarantsev,V. V. Sarantsev,S. G. Sherman
Physics , 2011, DOI: 10.1140/epja/i2011-11159-3
Abstract: The detailed investigation of the single pion production reactions $pp\to pn\pi^{+}$ and $pp\to pp\pi^{o}$ at the incident proton momentum 1628 MeV/c has been carried out. The data are analyzed in the framework of the event-by-event maximum likelihood method together with the $pp\to pp\pi^{0}$ data measured earlier in the energy region below 1 GeV. At 1628 MeV/c the largest contributions stem from the $^{3}P_{2}$, $^{3}P_{1}$, $^{3}P_{0}$, $^{1}D_{2}$ and $^{3}F_{2}$ initial partial waves.
