Abstract:

Measurements of the cross sections for charged current deep inelastic scattering in e+p collisions with a longitudinally polarised positron beam are presented. The measurements are based on a data sample with an integrated luminosity of 132 pb-1 collected with the ZEUS detector at HERA at a centre-of-mass energy of 318 GeV. The total cross section is presented at positive and negative values of the longitudinal polarisation of the positron beams. The single-differential cross-sections dσ/dQ2, dσ/dx and dσ/dy are presented for Q2>200 GeV2. The reduced cross-section σ̃ is presented in the kinematic range 200

Conference summary

Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment 623:1 (2010) 80-81

Abstract:

How does one summarise a summary? Briefly. • TIPP09, the first of a new IUPAP-sponsored series, has made a fantastic start and promises that TIPP will be as distinguished a series as Rochester and LPS. The next conference will be hosted in two years time by Fermilab in the Chicago area. • The whole area of detectors and accelerators is in rapid and continuous development. There will be lots to report every two years. The scope of TIPP will continue to grow as the imperative to transfer technology to other fields is increasingly recognised. • We are approaching a cusp in particle physics. In these turbulent times, we must convince governments and colleagues that particle physics is a subject in which it is worth investing. We have an excellent story. With the courage and imagination of our predecessors, we can succeed. © 2010 Elsevier B.V. All rights reserved.

Micron size laser-wire system at the ATF extraction line, recent results and ATF-II upgrade

Abstract:

The KEK Accelerator test facility (ATF) extraction line laser-wire system has been upgraded last year allowing the measurement of micron scale transverse size electron beams. The last measurements using the upgraded system from recent operation at the ATF are presented, demonstrating raw measurements of order 3μm RMS. The main component contributions to this measurement are also discussed. © 2010 Elsevier B.V. All rights reserved.

Abstract:

Beauty production in deep inelastic scattering with events in which a muon and a jet are observed in the final state has been measured with the ZEUS detector at HERA using an integrated luminosity of 114 pb-1. The fraction of events with beauty quarks in the data was determined using the distribution of the transverse momentum of the muon relative to the jet. The cross section for beauty production was measured in the kinematic range of photon virtuality, Q2>2 GeV2, and inelasticity, 0.05

Abstract:

A combination is presented of the inclusive deep inelastic cross sections measured by the H1 and ZEUS Collaborations in neutral and charged current unpolarised e±p scattering at HERA during the period 1994-2000. The data span six orders of magnitude in negative four-momentum-transfer squared, Q2, and in Bjorken x. The combination method used takes the correlations of systematic uncertainties into account, resulting in an improved accuracy. The combined data are the sole input in a NLO QCD analysis which determines a new set of parton distributions, HERAPDF1.0, with small experimental uncertainties. This set includes an estimate of the model and parametrisation uncertainties of the fit result.
