Overlap Study of V0 daughters and jet track by DCA

From the former study, There is a bump in L/K ratio at 7 TeV, then maybe one reason is the Overlap of V0 daughters and jet track,

Select the hybrid track and V0 candidates

if (t) continue;
jetID=t->GetID();
if (t->IsGlobalConstrained()){ // constrained tracks have a changed ID
jetID = -1-jetID;
}

and I found the phi of V0s in jet is not uniform
 After that I check the ratio about Single V0s and Matched V0s ,I fount the Matched Kshort and Lambda have slightly difference on high pT 85% and 94%, which will increase 10% of ratio.

and the eta cut nearly cut the same fraction of V0s,

Jet Reconstruct with jet and V0 vectors

Inclusive_4Type.pngInclusive_4Type_2.png

This two plot show the Inclusive and Single V0s ,and also include the matched V0s with eta 7GeV/c, and the new method with eta <0.35 and the pt of new jet(jet and V0s as input vectors) in 0/15GeV

The plot shows that the new method with pt>0 GeV. Its consistent with Inclusive V0s, and when you applied a pt>15GeV/c the results consistent with 7GeV/c

SingalBackgroundRatio.pngNsigma.png

These two plots, asked by my supervisor, one is the Signal and background ratio for inclusive V0s ,Check the Note from LF, It's consistent

and the other one shows the result about the counts of InvMass in each Sigma bins, especially for the N sigma in 3-4 and 6-7.

After that I check the ratio about Single V0s and Matched V0s ,I fount the Matched Kshort and Lambda have slightly difference on high pT 85% and 94%, which will increase 10% of ratio.

and the eta cut nearly cut the same fraction of V0s,

the Jet PT ,will cut the different fraction of V0s, keep 50 % for kshort, and 70% for lambda. which will increase the 40% of the ratio

Check the bump use LHC10d AND LHC10e bump exist

Change Jet R=0.4 and R=0.2, bump exist

Change V0 eta acceptance,bump exist

Leading Track Pt ,introduce bias. do not applied

Jet aea has a small effect on bump.

Select no pileup V0s, bum exist

Increase the Jet Pt , the bump exist and the statistics become lower. don't trust this results.

Maybe : 1. suppress the kshort production in jet.

The count at pt 10~12GeV/c of Lambda, It goes down to 20 counts, and its quite small ,and we already know due to the code bug, we overestimate the 22% of Good Event.

New Analysis without fiducial cut on jet

rerun the data sample without fiducial cut on jet,

1. Nearly 2.3\% $\Vzeros$ come from a event without jet,

2. Actrually, the jet clusters area in per event only take nearly 36.9% of the acceptance, since the multiplicity in pp collisions is small. After the jet with a minimum $\pT$ 0.15 $\GeVc$ to exclude the ghost jets. There are large fraction of vacant area (no jet), the $\Vzero$ located in this area will have a large possibility to be a Single $\Vzero$ -- no matched jet in acceptance <0.9

3. Applied fiducial and $\pT$ cuts to the combined clusters will introduce a acceptance cut on $\Vzeros$ ,the $\Vzeros$ located in the large $\eta$ will have a large possibiltiy to be a Single $\Vzeros$ -- have matched jet in acceptance <0.9 but no matched jet in acceptance <0.35

The frist case explained as small fraction of hard scattering processes in those events, The second case explained as small multiplicity in pp collisions. The third one explained as a fiducial cut

Discussion :

Expection:

--lower $\pT$ $\Vzeros$, case one will hava a main effect on lower $\pT$ part, since soft process generated $\Vzeros$ will contribute a large fraction to lower $\pT$, the vacant area will have a uniform effect on lower part, the vacant area give a hint about the particles inside it are not generated by hard processes.

--high $\pT$ $\Vzeros$, case one should have a small effect on high $\pT$ part, the vacant area have a unknow effect on high $\pT$, but It should be less than the lower $\pT$, There are situations about the $\Vzeo$ with a $\pT$ higher than 7\~8 $GeVc$ should came from a jet, but 1.) the $\Vzero$ take a large fraction of the jet, and the residual particles only have a very small fraction of $\pT$, during the jet reconstrution step. this jet have been lost, 2.)the $\Vzero$ take a small fraction of jet, and the jet reconstucted with a long distance to $\Vzero$

\mrk{The third case will have the same effect on lower $\pT$ and higher $\pT$ if the $\Vzeros$ production have no dependence on $\eta$ acceptance}

Area_Fraction.png

This plot show the jet Area fraction in each event, and used to prove, There are some vacant area in each event, the average jet area in each event is nearly 0.369.

This three plots show the Single V0s and Matched V0s without any fiducial and pt cut distribution, It show that the Single V0s have a large possibility in low pT and nearly 50%, and become lower when v0 pt increase.

Spectra comparison

The following plots show the inclusive V0s production compared to matched to Jet V0s, and spectra normalized to MB event.

Jet_Inclusive_Comparision.pngRatio_Kshort.pngRatio_Lambda.pngRatio_AntiLa.png

From these plot, we can found there is a gap between inclusive and matched V0s, and then, try to figure out the reason, why the high transverse momentum V0s not come from the jet.

Hint:

The Eta acceptance

The V0 applied a eta cut with 0.75 =>Inclusive V0 acceptance

In this analysis the Jet apply a eta cut with TPC acceptance(0.9) - jet radius(0.4)= 0.5,

Matched V0s, the Jet applied another eta cut wiht V0 acceptance - jet radius =0.35,

the eta acceptance have a influnence on the matched V0s.

The Single V0s

suppose there is one V0s located at eta = 0.6,with a pT=10 GeV /c , and There is a jet reconstructed in 0.6, due to the eta acceptance on jet, we will lost this V0s,

Improved Spectra comparison

Due to the jet reconstructed only with the charged track, so when applied a jet pT cut will lost some V0s from jet.

1. After finding jets associate every V0 with the closest highest pT jet but still within R and sum the pT jet and pTV0 to use as the jet

2. applied the new jet pt cut

The following plots show the new and older matched V0s, and spectra normalized to MB0 event.

From the plots, It shows this method contribute 10% to the matched V0 spectra

7GeV/c compare to 8GeV/c cut on Jet
