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...

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...

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...

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.
