Measurement of and Structure Functions in Low Region with the IHEP-JINR Neutrino Detector
The isoscalar structure functions and are measured as functions
of averaged over all permissible for the range of 6 to 28 GeV of
incident neutrino (anti-neutrino) energy at the IHEP-JINR Neutrino Detector.
The QCD analysis of structure function provides
MeV under the assumption of QCD
validity in the region of low . The corresponding value of the strong
interaction constant agrees with the
recent result of the CCFR collaboration and with the combined LEP/SLC result.Comment: 11 pages, 1 Postscript figure, LaTeX. Talk given at the 7th

Determination of the high-twist contribution to the structure function
We extract the high-twist contribution to the neutrino-nucleon structure
function from the analysis of the data collected by
the IHEP-JINR Neutrino Detector in the runs with the focused neutrino beams at
the IHEP 70 GeV proton synchrotron. The analysis is performed within the
infrared renormalon (IRR) model of high twists in order to extract the
normalization parameter of the model. From the NLO QCD fit to our data we
obtained the value of the IRR model normalization parameter
. We
also obtained from a similar fit to the CCFR data. The average of both results is

Direct Observation of PI-2(1680) in the RHO-0-PI-System
In the reaction of x- dissociation into a p+p-z'- system on a Cu nucleus, a clear enhancement in the poz- effective-mass distribution has been observed in the 1;2( 1680) region. Partial-wave analysis shows that this enhancement is due to the P-wave and has a resonant nature. Coherent and incoherent cross-sections for this enhancement have been measured

Shape, transverse size, and charged-hadron multiplicity of jets in pp collisions at
Measurements of jet characteristics from inclusive jet production in
proton-proton collisions at a centre-of-mass energy of 7 TeV are presented. The
data sample was collected with the CMS detector at the LHC during 2010 and
corresponds to an integrated luminosity of 36 inverse picobarns. The mean
charged hadron multiplicity, the differential and integral jet shape
distributions, and two independent moments of the shape distributions are
measured as functions of the jet transverse momentum for jets reconstructed
with the anti-kT algorithm. The measured observables are corrected to the
particle level and compared with predictions from various QCD Monte Carlo
generators.Comment: Replaced with published version. Added journal reference and DOI.
