The Jet Energy Scale Group
Group Leader: V.Daniel Elvira
Meeting Time: we used to
meet every week in the past. Now we handle Run I energy
scale issues in the KT
group meetings and individual discussions.
The aim of the group
was to develop a method to perform the absolute jet energy calibration
to a high degree of accuracy for Run I (1992-1995). It was primarily based
on physics principles using collider data, given the lack of a central
tracking magnetic device in the Run I D0 detector. The group has produced
a number of publications, conference proceedings and
notes.
Minutes
of the weekly meetings (1996-1997) are available. You can also read the
minutes of the
KT
jet meetings for KT information. A graphic
description of the energy scale analysis is available at the bottom
of this page.
