We propose a version of the QCD-motivated “k⊥” jet-clustering algorithm for hadron-hadron
collisions which is invariant under boosts along the beam directions. This leads to improved …

The jet shape is a simple measure of how widely a jet's energy is spread. At present jet
shape distributions have only been calculated to leading order in perturbative QCD. In this …

We study the two-jet inclusive cross section via the triply differential distribution d 3 σ d ET d
η 1 d η 2 to next-to-leading order in QCD. The predicted distributions can be compared …

We describe a cone-based jet finding algorithm (similar to that used in ̄ pp experiments),
which we have applied to hadronic events recorded using the OPAL detector at LEP …

A search for single-top production, ep→ etX, has been made with the ZEUS detector at
HERA using an integrated luminosity of 130.1 pb− 1. Events from both the leptonic and …

Inclusive-jet cross sections have been measured in the reaction ep→ e+ jet+ X for photon
virtuality Q2< 1 GeV2 and γp centre-of-mass energies in the region 142< Wγp< 293 GeV …

A method to distinguish between light-quark jets and gluon jets in a calorimeter detector is
presented. The method could be used to refine the experimental test of QCD based on the …

Single-and double-differential inclusive dijet cross sections in neutral current deep inelastic
ep scattering have been measured with the ZEUS detector using an integrated luminosity of …

Jet substructure and differential cross sections for jets produced in the photoproduction and
deep inelastic ep scattering regimes have been measured with the ZEUS detector at HERA …

Differential inclusive-jet cross sections have been measured for different jet radii in neutral
current deep inelastic ep scattering for boson virtualities Q2> 125 GeV2 with the ZEUS …
