Lattice Quantum ChromoDynamics with approximately chiral fermions
, 2008 In this work we present Lattice QCD results obtained by approximately chiral fermions. We use the CI fermions in the quenched approximation to investigate the excited baryon spectrum and to search for the Theta^+ pentaquark on the lattice. Furthermore we

Parton distributions and small X physics [PDF]
, 1992 We determine the parton distributions of the pion from a consistent next-to-leading order analysis of several high statistics π±N experiments including both Drell-Yan and prompt photon production.

Perturbative predictions for 4 jet production at LEP and prompt photon emission at the tevatron [PDF]
, 1999 Many contemporary experimental QCD results achieve greater accuracy in measurement than equivalent theoretical predictions calculated at leading order.

Transverse momentum resummation and analytic continuation into the deep infrared
European Physical Journal C: Particles and FieldsExtracting information on the three-dimensional structure of hadrons from transverse-momentum data is a challenging task, requiring the separation of perturbative contributions under QCD control from genuinely non-perturbative effects, unavoidably ...

Signals of the QCD Phase Transition in the Heavens
, 2007 The modern phase diagram of strongly interacting matter reveals a rich structure at high-densities due to phase transitions related to the chiral symmetry of quantum chromodynamics (QCD) and the phenomenon of color superconductivity.

A non-perturbative study of the infra-red behaviour of QCD [PDF]
, 1989 The non-perturbative behaviour of the non-Abelian gauge theory of strong interactions, namely QCD, is investigated using the Schwinger-Dyson equations.

Hadron multiplicity fluctuations in perturbative QCD
Journal of High Energy PhysicsWe examine hadron multiplicity fluctuations in hard processes and confront analytic QCD predictions with the pattern of multiplicity fluctuations observed in e + e − annihilation and high-p t jets produced in pp collisions at the LHC. Special emphasis is

Recalculation of Proton Compton Scattering in
, 2000 At very high energy and wide angles, Compton scattering on the proton ( p! p) is described by perturbative QCD. The perturbative QCD calculation has been performed several times previously, at leading twist and at leading order in s, with mutually ...

Non-perturbative QCD effects in jets at hadron colliders
, 2008 We discuss non-perturbative QCD contributions to jet observables, computing their dependence on the jet radius R, and on the colour and transverse momentum of the parton initiating the jet.
