УСЛОВИЯ И ОРГАНИЗАЦИЯ ПЕРЕХОДА К БАЗОВЫМ ТЕХНОЛОГИЯМ НОВОГО ТЕХНОЛОГИЧЕСКОГО УКЛАДА
With due account for the coming new (VI-th) world technological structure, future creation of new types of industrial production is both possible and necessary. Economic environment conditions favorable for such development are designated. In reference to Russian technologicalenvironment particulars, self-developing economic-technological microenvironment of a new quality level should be created in zones where controlled «technological chains» function. Possibilities of creation of the VI-th technological structure level basic technologies are shown for industrial and household waste processing techniques as an example.В перспективе возможно, а с учетом формирующегося в мире нового (VI-го) технологического уклада необходимо создание новых промышленных производств. Обозначены условия экономической среды, благоприятствующие такому развитию. Применительно к российским особенностям технологической среды необходимым является создание саморазвивающейся экономико-технологической макросреды нового уровня качества в зонах функционирования управляемых «технологических цепочек».

Evidence for the exclusive decay Bc+- to J/psi pi+- and measurement of the mass of the Bc meson
We report first evidence for a fully reconstructed decay mode of the
B_c^{\pm} meson in the channel B_c^{\pm} \to J/psi \pi^{\pm}, with J/psi \to
mu^+mu^-. The analysis is based on an integrated luminosity of 360 pb$^{-1} in
p\bar{p} collisions at 1.96 TeV center of mass energy collected by the Collider
Detector at Fermilab. We observe 14.6 \pm 4.6 signal events with a background
of 7.1 \pm 0.9 events, and a fit to the J/psi pi^{\pm} mass spectrum yields a
B_c^{\pm} mass of 6285.7 \pm 5.3(stat) \pm 1.2(syst) MeV/c^2. The probability
of a peak of this magnitude occurring by random fluctuation in the search
region is estimated as 0.012%.Comment: 7 pages, 3 figures. Version 3, accepted by PR
Top quark mass measurement using the template method at CDF
We present a measurement of the top quark mass in the lepton+jets and
dilepton channels of decays using the template method. The data
sample corresponds to an integrated luminosity of 5.6 fb of
collisions at Tevatron with TeV, collected with the CDF II
detector. The measurement is performed by constructing templates of three
kinematic variables in the lepton+jets and two kinematic variables in the
dilepton channel. The variables are two reconstructed top quark masses from
different jets-to-quarks combinations and the invariant mass of two jets from
the decay in the lepton+jets channel, and a reconstructed top quark mass
and , a variable related to the transverse mass in events with two
missing particles, in the dilepton channel. The simultaneous fit of the
templates from signal and background events in the lepton+jets and dilepton
channels to the data yields a measured top quark mass of Comment: submitted to Phys. Rev.
Measurement of the Inclusive Jet Cross Section in ppbar Interactions at sqrt{s}=1.96 TeV Using a Cone-based Jet Algorithm
We present a measurement of the inclusive jet cross section in ppbar
interactions at sqrt{s}=1.96 TeV using 385 pb^{-1} of data collected with the
CDF II detector at the Fermilab Tevatron. The results are obtained using an
improved cone-based jet algorithm (Midpoint). The data cover the jet transverse
momentum range from 61 to 620 GeV/c, extending the reach by almost 150 GeV/c
compared with previous measurements at the Tevatron. The results are in good
agreement with next-to-leading order perturbative QCD predictions using the
CTEQ6.1M parton distribution functions.Comment: 19 pages, 2 figures, 1 tabl
Measurement of and Production in Collisions at = 1.96 TeV
The Standard Model predictions for and production are
tested using an integrated luminosity of 200 pb of \ppbar collision data
collected at the Collider Detector at Fermilab. The cross sections are measured
selecting leptonic decays of the and bosons, and photons with
transverse energy GeV that are well separated from leptons. The
production cross sections and kinematic distributions for the and
are compared to SM predictions.Comment: 7 pages, 4 figures, submitted to PR
Measurement of the Lifetime Difference Between B_s Mass Eigenstates
We present measurements of the lifetimes and polarization amplitudes for B_s
--> J/psi phi and B_d --> J/psi K*0 decays. Lifetimes of the heavy (H) and
light (L) mass eigenstates in the B_s system are separately measured for the
first time by determining the relative contributions of amplitudes with
definite CP as a function of the decay time. Using 203 +/- 15 B_s decays, we
obtain tau_L = (1.05 +{0.16}/-{0.13} +/- 0.02) ps and tau_H = (2.07
+{0.58}/-{0.46} +/- 0.03) ps. Expressed in terms of the difference DeltaGamma_s
and average Gamma_s, of the decay rates of the two eigenstates, the results are
DeltaGamma_s/Gamma_s = (65 +{25}/-{33} +/- 1)%, and DeltaGamma_s = (0.47
+{0.19}/-{0.24} +/- 0.01) inverse ps.Comment: 8 pages, 3 figures, 2 tables; as published in Physical Review Letters
