Run-13 Projected Impact on Run-12 W+/W- Cross Section Ratio

Combines preliminary Run-12 W+/W- cross section ratio with current Run-13 cross section ratio.
Run-13 ratio is described here:

QA of individual jets

This QA was performed on the individual jets comprising a di-jet event. All the attached pdfs show the same data for the individual triggers.

Run12 pp 200GeV high multiplicity trigger: Pt distribution

Motivation:

Is there more jet in high multiplicity?
Is mean pt higher in high multiplicity? 

Dataset:

run 12 pp 200GeV

Comparison KFParticle vs. Helix swimming for secondary vertex reconstruction

Simulation :

D0 Reconstruction comparing Helix Swimming (HS) and KFParticle (KF)

About 62M events within |Vz|<6cm from official production.

Common cuts
pT1>1.2, pT2>1.2 GeV/c

Hijing + HF simulations

 I have provided template code used to produce D0's in a hijing background, the files can be located in:
