The DØ Experiment’s Integrated Luminosity for Tevatron Run IIa
نویسندگان
چکیده
An essential ingredient in all cross section measurements is the luminosity used to normalize the data sample. In this note, we present the final assessment of the integrated luminosity recorded by the DØ experiment during Tevatron Run IIa. The luminosity measurement is derived from hit rates from the products of inelastic proton-antiproton collisions registered in two arrays of scintillation counters called the luminosity monitor (LM) detectors. Measured LM rates are converted to absolute luminosity using a normalization procedure that is based on previously measured inelastic cross sections and the geometric acceptance and efficiency of the LM detectors for registering inelastic events.

A Precision Measurement of the W Boson Mass with 1 Fb−1 of Dø Run Iia Data
by Jyotsna Osta This thesis is a detailed presentation of a precision measurement of the mass of the W boson. It has been obtained by analyzing W → eν decays. The data used for this analysis was collected from 2002 to 2006 with the DØ detector, during Run IIa of the Fermilab Tevatron collider. It corresponds to a total integrated luminosity of 1 fb−1. With a sample of 499,830 W → eν candidate e...

Run 2 of the Tevatron collider at Fermilab has begun in the spring of 2001. During its first year of operation the Tevatron has delivered an integrated luminosity of approximately 30 pb −1 to the DØ experiment. These data have been used to commission the detector. The progress in understanding the detector performance and the prospects for an exciting physics program to be carried out in the ne...
متن کاملPresent Searches for Higgs Signatures at the Tevatron
We present results for various searches for signatures of standard and non-standard model Higgs boson decays conducted at the collider detectors CDF and DØ using ≈ 100 pb −1 of integrated luminosity each from the Tevatron collider Run 1 (1992-96) at √ s = 1.8 TeV. No evidence for a Higgs boson decay is found and various limits are set.
متن کاملRecent Qcd Studies at the Tevatron
Since the beginning of Run II at the Fermilab Tevatron, the QCD physics groups of the CDF and DØ experiments have worked to reach unprecedented levels of precision for many QCD observables. Thanks to the large dataset over 3 fb of integrated luminosity recorded by each experiment many important new measurements have recently been made public and will be summarized in this paper.
