ON the question of the uniqueness of the energy-momentum complex in the special and general theory of relativity

Modification of the Fock method is used to look systematically for the complexes of energy and momentum which are conserved as a consequence of the vacuum field equations of the second order (real and complex scalar field, real vector field, symmetric tensor field of the linearized and non-linear Einstein theory). In contrast to Fock's results for fields described by equations of the first order, the complexes are not defined uniquely. The non-uniquenesses are eliminated by supplementary conditions.This paper is based on a diploma thesis worked out at the Department of Theoretical Physics, Faculty of Mathematics and Physics, Charles University.

The center of nuclear physics data at the All-Russia Research Institute of Experimental Physics

The Center of Nuclear Physics Data (All-Russia Research Institute of Experimental Physics) is a member of the International Nuclear Reaction Data Center Network, operating under the aegis of the International Atomic Energy Agency and founded to coordinate the collection, compilation, and dissemination of data among the world community. The Center of Nuclear Physics Data (CNPD) focuses on the compilation of experimental data on the interaction of charged particles with nuclei for the EXFOR international library. The center’s personnel are currently developing a software package that will make it possible to enter, edit, and record the data in the EXFOR format. The package includes all of the procedures for processing experimental data and ensuring compliance with the specified format.     

Vertical rotation effect on turbulence characteristics in an open channel flow

This paper solves the three-dimensional Navier-Stokes equation by a fractional-step method with the Reynolds number Reτ=194 and the rotation number Nτ=0-0.12. When Nτ is less than 0.06, the turbulence statistics relevant to the spanwise velocity fluctuation are enhanced, but other statistics are suppressed. When Nτ is larger than 0.06, all the turbulence statistics decrease significantly. Reynolds stress budgets elucidate that turbulence kinetic energy in the vertical direction is transferred into the streamwise and spanwise directions. The flow structures exhibit that the bursting processes near the bottom wall are ejected toward the free surface. Evident change of near-surface streak structures of the velocity fluctuations are revealed.

New physics contributions to the lifetime difference in D0-D0 mixing

We present the first general analysis of New Physics contributions to the D0-D[over ](0) lifetime difference (equivalently DeltaGamma(D)). We argue that New Physics (NP) contributions to |DeltaC|=1 processes can dominate the lifetime difference in the flavor SU(3) limit. We provide several specific examples of models that produce sizable effects in DeltaGamma(D) for realistic values of light quark masses, even if such NP contributions are undetectable in the current round of D0 decay experiments. This makes DeltaGamma(D) a viable observable for studies of indirect effects of New Physics.
