Jet Substructure at HERA

Measurements of jet shapes and subjet multiplicities in photoproduction performed by ZEUS are presented and compared to leading-logarithm parton-shower Monte Carlo models. The predicted differences on the size of gluon- and quark-initiated jets are used to select samples to study the dynamics of the subprocesses.Comment: 9 pages, 7 figures.

Jet production in deep inelastic ep scattering at HERA

Recent results from jet production in deep inelastic ep scattering at HERA are reviewed. The values of alpha_s(M_z) extracted from a QCD analysis of the data are presented.Comment: 9 pages, 5 figures, talk given at the ``Ringberg workshop: New trends in HERA Physics 2003'

When the City of London’s bubble burst, it was the state and the real economy that had to take the hit

Recently appointed Labour peer Maurice Glasman, a leader of London Citizens and considered the ‘father of Blue Labour’, reflects on how the UK got into the financial crisis and who will ultimately pay for it

The Structure of the Virtual Photon

Measurements of dijet cross sections for virtual photons are presented as a function of \xo, the fraction of the virtual photon energy invested in the production of the dijet system, using the ZEUS detector. Comparisons to QCD predictions show that a resolved photon component is needed to describe the data up to values of the photon virtuality comparable to the scale of the interaction.Comment: 9 pages, 6 figures.
