Monte Carlo study of gg->H+jets contribution to Vector Boson Fusion Higgs production at the LHC
The contribution of gg->H+jets production process to the vector boson fusion
production of the Higgs boson, VV->H, at LHC was evaluated with the ALPGEN
generator and the PYTHIA shower Monte Carlo including a jet-parton matching
procedure. After the experimental like event selections applied at PYTHIA
particle level, the contribution was found to be 4-5 % for a Higgs boson mass
of 120 GeV
ON THE RECORD PROPERTIES OF INTEGRATED TIME SERIES
This paper compares the statistical properties of the records from i.i.d. time series with those of time series containing a single unit root. It is shown that there are important differences in both the limiting distributions and the convergence rates of the associated record counting processes. Since the record properties of i.i.d. time series are shared by a large class of stationary time series, the reported differences underline the possibility of using record-based statistics for robust resting procedures of the unit root hypothesis.
Ballistic Localization in Quasi-1D Waveguides with Rough Surfaces
Structure of eigenstates in a periodic quasi-1D waveguide with a rough
surface is studied both analytically and numerically. We have found a large
number of "regular" eigenstates for any high energy. They result in a very slow
convergence to the classical limit in which the eigenstates are expected to be
completely ergodic. As a consequence, localization properties of eigenstates
originated from unperturbed transverse channels with low indexes, are strongly
localized (delocalized) in the momentum (coordinate) representation. These
eigenstates were found to have a quite unexpeted form that manifests a kind of
"repulsion" from the rough surface. Our results indicate that standard
statistical approaches for ballistic localization in such waveguides seem to be
unappropriate.Comment: 5 pages, 4 figure
