Perturbative and Non-perturbative QCD
I will describe recent developments in perturbative QCD focusing on progress in
understanding one-loop corrections to multi-jet processes.

Perturbative and Non-perturbative QCD
I present results for two-loop soft anomalous dimensions, which
are derived from dimensionally regularized diagrams with eikonal
quark lines and control soft-gluon emission in hard-scattering processes.
Detailed results for the UV poles of the eikonal integrals will be
shown for massive quarks, and the massless limit will also be taken.
The construction of soft anomalous dimensions at...

Perturbative and Non-perturbative QCD
In the context of HERWIG6.5, we present Monte Carlo data showing the comparison between the parton shower generated by the standard DGLAP-CS kernels and that generated by the new IR-improved DGLAP-CS kernels recently developed by one of us(BFLW). This is done by implementing the new kernels in HERWIG6.5 to generate a new MC, HERWIRI1.0, for hadron-hadron interactions at high energies. Possible...

Perturbative and Non-perturbative QCD
The large production rate of jets and photons at the LHC will provide
an ideal opportunity for testing perturbative QCD, for constraining the gluon
parton density function, as well as for searching for new physics. The finely
segmented calorimeters, together with an efficient tracking system, allows
for precision measurements of photons and jets. In this presentation, the
di-jet,...

Perturbative and Non-perturbative QCD
A sample of photon plus 3-jet events collected in the D0 experiment
with an integrated luminosity of 1fb-1 is used to determine the fraction
of the events with double parton (DP) scattering fDP in a single ppbar
collision at sqrt(s)=1.96TeV. The events are selected with photon
candidate transverse momentum between 60 and 80GeV, leading jet pT above
25GeV and two additional jets with...

We present the first measurement of dijet angular distributions
in Run II of the Fermilab Tevatron Collider. The measurement is
based on a dataset, corresponding to an integrated luminosity of
approx 0.7 fb-1 taken with the D0 detector. Shapes of dijet angular
distributions have been measured over a range of dijet masses,
from 0.25 TeV and beyond 1TeV. The data are in good agreement...

Perturbative and Non-perturbative QCD
We present measurements of differential cross sections in
inclusive Z/gamma plus jet production in a data sample of
1fb-1 collected with the D0 detector in proton antiproton
collisions at sqrt(s)=1.96TeV. Measured variables include
the Z/gamma transverse momentum (pT-Z), and rapidity (y-Z),
the leading jet pT (pT-jet), and rapidity (y-jet), as well
as various angles of the Z+jet...
