2009.11.11 Tests of EEMC geometry, version 6.1

Monte-Carlo setup:

Ecalgeo V6.1

Plot of reconstructed energy/input energy as a function of input energy - comparing cvs version with version 6, version 6.1 and version 6.1 with pure lead.  The replacement for pure lead means

Electron asymmetry

The goal is to obtain non-photonic electron asymmetry. To get there, various asymmetries need to be calculated, namely:

2009.11.10 BEMC sampling fraction and clustering

Monte-Carlo setup:

dE/dx cut, efficiency and electron purity

One of the electron id cut is the dE/dx cut. Unlike the other cuts, the efficiency of this cut is calculated from data instead of simulation.

Pre-embedding QA for W analysis II

Pre-embedding QA for W analysis II

Motivation:  Verify compatibility of MC signal W events with real background events (zerobias) before embedding begins. 

2006 p+p BEMC issue with upsilon triggers

notes on w error

 I've attached a latex document with some notes on sources of error for the W cross section.  Please note that the latest version is entitled WxSectV2.

Electron identification efficiency

The electron identificatione fficiency is calculated to determine how effective the electron identification process done in this analysis is, and hence how much electrons there actually are, given

Photonic electron reconstruction efficiency

Photonic electron reconstruction efficiency is the background rejection efficiency.

Simulation analysis: track association and identifcation

To calculate electron identification and photonic electron reconstruction efficiencies, simulation dataset for both 2005 and 2006 are used.
