decay channel in the ATLAS -mixing studies
It is shown, using a track-level simulation, that the use of the decay channel for reconstruction, in additioon with the
previously studied mode, enables two fold gain in the
ATLAS -mixing signal statistics through
-decay channel. A new modification of the amplitude fit method is
suggested for the determination. Some general aspects of the
-mixing phenomenon is illustrated by pictures of Casimir Malevich,
Maurits Cornelis Escher and Salvador Dali.Comment: 23 pages, LaTex, 7 figures and 4 picture
ATLAS sensitivity range for the x_s measurement
Previous results for the prospects of B_s mixing measurement in the ATLAS
experiment at LHC are updated. The improved analysis method of the studied
decay channels B_s -> D_s pi and B_s -> D_s a_1, combined with most recent
values for the branching ratios and the B_s lifetime, leads to the new ATLAS
sensitivity range for the x_s measurement: x_s^{max} = 42. An extensive study
is done in order to estimate how x_s^{max} is influenced by the B-decay
proper-time resolution of the vertex detector, as well as by the number of
events and by the signal-to-background ratio.Comment: 17 pages, incl. 12 figure
State corporations’ creation for more efficient management of public resources
In order to fulfill the tasks of sustainable state development, the creation of an innovative economy and the achievement of technological independence it is of particular importance to find ways to improve the efficiency of public resource management. Especially this concerns the development of measures to increase the impact of research and development, and the introduction of new technologies. As part of the implementation of this task, a statistical and economic analysis of the introduction effects of advanced production technologies at enterprises, including in the context of various forms of ownership has been carried out in the work. It is established that the best research results and development work are observed in companies with state participation, especially in state corporations. Thus, one of the most effective forms of innovation economy development in Russia is the further creation of state-owned companies in the most high-tech areas
