Evaluation of Run 9 BTOW Calibration for W analysis

Motivation:

QUARKONIUM 2010: J/ψ - hadron correlation and Upsilon production in p+p at STAR

Two short talks at workshop "QUARKONIUM 2010: Three days of Quarkonium Production in pp and pA collisions". 29 - 31 July, 2010

Large Cell HV curves

MinuitVF 200 GeV for run 10

Analysis cuts for Vertex Selection 39,7.7,11 GeV

This blog investigates the cuts that will be necessary to select Au+Au collisions from the background in low energy collisions in 2010.

Background events consist of:

DIS10 Proceedings - "Diffractive Physics Program with Tagged Forward Protons at STAR/RHIC"

Drift velocity

The four plots are:

1. Difference between drift velocity (west-east) vs. time(hrs).

2. Difference between drift velocity (west-east) vs. time(day).

In this reproduction, the main changes are :

ToF Gas System Mapping

The gas flows over 24 sectors. The first tray listed in each sector is the input side.
