  1. 165. New features in version 2 of the fastNLO project
    Daniel Andreas Britzger (DESY)

    Hadronic final states/structure functions
    Standard methods for higher-order pQCD calculations of cross sections in hadron-induced collisions are time-consuming. The fastNLO project uses multi-dimensional interpolation techniques to convert the convolutions of perturbative coefficients with parton distribution functions and the strong coupling into simple products. By integrating the perturbative coefficients for a given...

  2. 71. Inclusive jet production measured with ATLAS, and constraints on PDFs
    Dr Bogdan Malaescu (CERN)

    Hadronic final states/structure functions
    Inclusive jet and dijet double-differential cross sections have been measured in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS detector. The cross sections were measured using jets clustered with the anti-kT algorithm. The measurements are performed in the jet rapidity range |y|<4.4, covering jet transverse momenta from 20 GeV to 1.5 TeV and dijet...

  4. 267. On the timelike splitting functions at NNLO and beyond
    Andreas Vogt (University of Liverpool)
    29/03/2012, 10:00
    Hadronic final states/structure functions
    We present the third-order (NNLO) contributions to the timelike splitting functions governing the evolution of parton fragmentation functions in QCD. The hitherto missing quark-gluon and gluon-quark quantities have been derived by studying physical evolution kernels for photon- and Higgs-exchange DIS structure functions and their counterparts in semi-inclusive annihilation, together with...

  5. 96. A new approach to hadron multiplicity ratio
    Paolo Bolzoni (DESY)
    29/03/2012, 10:20
    Hadronic final states/structure functions
    We present a new approach in considering and including the perturbative and non-perturbative contributions to the gluon-quark multiplicity ratio. The new method is motivated by new developments in timelike small x resummation and exploit the recently computed NNLO timelike splitting fnctions. Comparison of our new results with other methods and with data will also be presented.
