Abstract:

For comparison of inclusive jet cross sections measured at hadron-hadron colliders to next-to-leading order (NLO) parton-level calculations, the energy deposited in the jet cone by spectator parton interactions must first be subtracted. The assumption made at the Tevatron is that the spectator parton interaction energy is similar to the ambient level measured in minimum bias events. In this paper, we test this assumption by measuring the ambient charged track momentum in events containing large transverse energy jets at [Formula Presented] and [Formula Presented] and comparing this ambient momentum with that observed both in minimum bias events and with that predicted by two Monte Carlo models. Two cones in [Formula Presented] space are defined, at the same pseudorapidity, [Formula Presented], as the jet with the highest transverse energy ([Formula Presented]), and at [Formula Presented] in the azimuthal direction, [Formula Presented]. The total charged track momentum inside each of the two cones is measured. The minimum momentum in the two cones is almost independent of [Formula Presented] and is similar to the momentum observed in minimum bias events, whereas the maximum momentum increases roughly linearly with the jet [Formula Presented] over most of the measured range. This study was carried out using data from the CDF detector taken during Run 1 (1994-1995). The study will help improve the precision of comparisons of jet cross section data and NLO perturbative QCD predictions. The distribution of the sum of the track momenta in the two cones is also examined for five different [Formula Presented] bins. The HERWIG and PYTHIA Monte Carlo generators are reasonably successful in describing the data, but neither can describe completely all of the event properties. © 2004 The American Physical Society.

Design study for the KMOS spectrograph module

P SOC PHOTO-OPT INS 5492 (2004) 1395-1402

Authors:

M Tecza, N Thatte, I Lewis, J Lynn, W Lau, S Yang, I Tosh, M Wells

Abstract:

We present the results of a design study for the spectrograph module for KMOS - a cryogenic near-infrared multi-object spectrograph being developed as a second generation instrument for the VLT by a consortium of UK and German institutes. KMOS will consist of 24 deployable integral field units feeding three identical spectrograph units via image slicers. The spectrographs are designed to provide a resolving power greater than 3000, so as to provide adequate OH avoidance, whilst covering one of the J, H or K bands within a single exposure. We present the opto-mechanical layout of the spectrographs, together with an analysis of the impact of the image quality (and PSF uniformity) on the accuracy of sky background subtraction within each IFU's field of view.
