K star

Files: pdsf>/eliza1/starprod/embedding/KstarM* ( July 31 2007)

Plots for Dedx, Mips, eta, phi distributions and vertex position on K star embedding are attached. Just around 20% of K star Minus files  could be scanned due to space issues (in my home dir) at pdsf. Reconstructed tracks were done just on Daugther Pions. There is little difference(0.036) in the mips position possible due to lack of statistics.

Plots - Dca Distributions

The Following are the results for dca distributions for different pT bins in Pi Minus. The results of dca agrees reasonable for the cut-off of 2 cm and above. These plots were done using the macro plot_dca.C

QA Plots Phi(Feb 2009)

QA P06ib (Phi->K +K)

 

This is the QA for P06ib (Phi- > KK). reconstruction on Global Tracks (Kaons)

1. dEdx

Reconstruction on Kaon Daugthers. Plot shows MOntecarlo tracks and Ghost Tracsks.

  

 

2. DCA Distributions

An original 3D histogram had been created  and filled with pT, Eta and DCA as the 3 coordinates. Projection on PtBins and EtaBins had been made to create this "matrix" of plots. (MonteCarlo and MuDst) (MuDst taken from pdsf > /eliza12/starprod/reco/cuProductionMinBias/ReversedFullField/P06ib/2005/022/st_physics_adc_6022048_raw*.MuDst.root)

Pt Bin array  used : { 0.5, 0.6, 0.8, 1.0} (moves down) and

Eta Bin array : {0.2, 0.5, 0.8, 1.0} (moves to the right)

For the Error bars, i used the option hist->Sumw2();

 

 

3. NFit Distributions

Similarly An Original 3D Histogram had been created with Pt, Eta and Nfit as coordinates. Respective projections had been made  in the same pT  and Eta Bins as the DCa distributions. (MonteCarlo and MuDst)

Pt Bin array  used : { 0.5, 0.6, 0.8, 1.0} (moves down) and

Eta Bin array : {0.2, 0.5, 0.8, 1.0} (moves to the right)

For the Error bars, i used the option hist->Sumw2();
