Update to Jet Study

I have updated some of the plots for the jet energy study I conducted. The following plots show the effect of a single type of particle on the jet energy we find.

Guidelines For MIT Tier2 Job Requests

Under:

In order to facilitate the submission of jobs, all requests for the Tier2 must contain the following information.  Note that, because we cannot maintain stardev on Tier2, all jobs must be run

SpaceCharge in dAu

Under:

In Run VIII, dAu data was acquired at high enough luminosities to worry about SpaceCharge (it was ignored previously in the Run III dAu data (2003)).

EEmc Gammas via conversion method

 

Abstract:
 
We use the preshower subsytem to statistically extract single-photon yields in the EEmc.  The method is similar to that employed by CDF [1].  An isolated sample of photon candidates is identified above pT > 5.0 GeV in the endcap.  Gamma candidates with charged particles within R < 0.3 are vetoed using the 1st preshower layer.  The remaining candidates should be primarily composed of neutral particles.  Based on the differential probabilities for 1 versus 2 photons to convert in the first radiator and deposit energy in preshower-2, it is then possible to extract a photon yield.
 
What follows is a "proof-of-principle" analysis.  The biggest "trick" is determining the conversion probabilities for the signal and background events, and this will need to be investigated further to quantify systematic uncertainties.
 

Frank's Jet Blog

Inspired by Matt Walkers study I have started a Geant4 investigation of the BEMC response to various particles. A very first look is shown in the attached pdf file.

Mass Windows

The nominal mass window was chosen 'by eye' to maximize the number of pion candidates extracted while minimizing the backgrounds (see yield extraction page.)  I wanted to check to see how this

Single Spin Asymmetries

The plots below show the single spin asymmetries (SSA) for the blue and yellow beams, as a function of run index.  These histograms are then fit with flat lines.  The SSA's are consistent
