A Vertex Trigger based on Cylindrical Multiwire Proportional Chambers
J. Becker, K. Bösiger, L. Lindfeld +14
The article describes the technical implementation and the performance of the z-vertex trigger (CIP2k), which is part of the H1-experiment at HERA.
Four-Loop Anomalous Dimensions for Radiative Flavour-Changing Decays
Michal Czakon, Ulrich Haisch, Mikolaj Misiak
We evaluate the complete four-loop anomalous dimension matrix that is necessary for determining the effective flavour-changing neutral current couplings qbar-q'-gamma and qbar-q'-g…
Effectivity of Brauer-Manin obstructions
Andrew Kresch, Yuri Tschinkel
We study Brauer-Manin obstructions to the Hasse principle and to weak approximation with special regard to effectivity questions.
Antenna subtraction with hadronic initial states
A. Daleo, T. Gehrmann, D. Maitre
The antenna subtraction method for the computation of higher order corrections to jet observables and exclusive cross sections at collider experiments is extended to include hadron…
New structural variation in evolutionary searches of RNA neutral networks
Sumedha, Olivier C Martin, Andreas Wagner
RNA secondary structure is an important computational model to understand how genetic variation maps into phenotypic (structural) variation. Evolutionary innovation in RNA structur…
Measurement of the ppbar to ttbar production cross section at sqrt(s)=1.96 TeV in the fully hadronic decay channel
D0 Collaboration, V. Abazov
A measurement of the top quark pair production cross section in proton anti-proton collisions at an interaction energy of sqrt(s)=1.96 TeV is presented. This analysis uses 405 pb-1…
Bottom production cross section from double muonic decays of b-hadrons in 920 GeV proton-nucleus collision
B Collaboration, I. Abt
The b-bbar production cross section in 920 GeV proton-nucleus fixed target collisions is measured by observing double muonic decays of b-flavored hadrons in the kinematic region $-…
Two-Loop Renormalization in the Standard Model Part I: Prolegomena
S. Actis, A. Ferroglia, G. Passarino +1
In this paper the building blocks for the two-loop renormalization of the Standard Model are introduced with a comprehensive discussion of the special vertices induced in the Lagra…
Search for techniparticles in e +jets events at D0
D0 Collaboration, V. Abazov
We search for the technicolor process ppbar -> rho_T/omega_T ->W+pi_T in events containing one electron and two jets, in data corresponding to an integrated luminosity of 390 pb-1,…
An Avoidance Principle with an Application to the Asymptotic Behaviour of Graded Local Cohomology
M. Brodmann, S. Kurmann, F. Rohrer
We present an Avoidance Principle for certain graded rings. As an application we fill a gap in the proof of a result by Brodmann, Rohrer and Sazeedeh about the antipolynomiality of…
Smooth tail index estimation
Samuel Müller, Kaspar Rufibach
Both parametric distribution functions appearing in extreme value theory - the generalized extreme value distribution and the generalized Pareto distribution - have log-concave den…
Search for single production of scalar leptoquarks in p\bar{p} collisions decaying into muons and quarks with the D0 detector
D0 Collaboration, V. Abazov
We report on a search for second generation leptoquarks LQ_2 which decay into a muon plus quark in p\bar{p} collisions at a center-of-mass energy of sqrt{s} = 1.96 TeV in the D0 de…
Two types of Hc2(T) dependences in Bi_2Sr_2Ca_(1-x)Y_xCu_2O_(8+delta) with different Yttrium content
I. L. Landau, H. Keller
We reanalyze the magnetization data collected on Bi_2Sr_2Ca_(1-x)Y_xCu_2O_(8+y) samples (Kim at al, Phys. Rev. B 72, 64525 (2005)) and argue that the method, which was used for the…
Supermassive black hole binaries in gaseous and stellar circumnuclear discs: orbital dynamics and gas accretion
M. Dotti, M. Colpi, F. Haardt +1
The dynamics of two massive black holes in a rotationally supported nuclear disc of 10^8 solar masses is explored using N-Body/SPH simulations. Gas and star particles are co-presen…
Small Visible Energy Scalar Top Iterative Discriminant Analysis for Different Center-of-Mass Energies
A. Sopczak, A. Finch, A. Freitas +2
Light scalar top quarks with a small mass difference with respect to the neutralino mass are of particular cosmological interest. This study uses an Iterative Discriminant Analysis…
On double Hurwitz numbers in genus 0
Sergei Shadrin, Michael Shapiro, Alek Vainshtein
We study double Hurwitz numbers in genus zero counting the number of covers $\CP^1\to\CP^1$ with two branching points with a given branching behavior. By the recent result due to G…
On Triple-Cut of Scattering Amplitudes
Pierpaolo Mastrolia
It is analysed the triple-cut of one-loop amplitudes in dimensional regularisation within spinor-helicity representation. The triple-cut is defined as a difference of two double-cu…
Coisotropic embeddings in Poisson manifolds
A. S. Cattaneo, M. Zambon
We consider existence and uniqueness of two kinds of coisotropic embeddings and deduce the existence of deformation quantizations of certain Poisson algebras of basic functions. Fi…

D0 Collaboration, V. Abazov
We report a new measurement of the ttbar production cross section in pbarp collisions at a center-of-mass energy of 1.96 TeV using events with one charged lepton (electron or muon)…
Zig-zag and Replacement Product Graphs and LDPC Codes
Christine A. Kelley, Deepak Sridhara, Joachim Rosenthal
The performance of codes defined from graphs depends on the expansion property of the underlying graph in a crucial way. Graph products, such as the zig-zag product and replacement…
