---+ Analysis pp 7 TeV :

---++ xE Distribution

*April 29, 2015*
Decide to re-use the Twiki after a long break.
The analysis is moving on. All the code is done. We are in check period.

For the moment we check if all the gamma decay contributions are compatible --&gt; %BLUE%TRUE%ENDCOLOR%

Check if UE is negligible --&gt; %BLUE%TRUE%ENDCOLOR%

Check if efficiency in away side and UE is compatible --&gt; %RED%FALSE%ENDCOLOR%

---++ Purity

The method has completely changed since Nicolas's thesis.
Now we take into account the contamination coming from gamma decays (neutral meson) in the signal region.

*23/06/2014*

Run the pp data on my code to crosscheck pp results : I don't have the same distributions =&gt; I do the x_E distribution for non isolated pi0 and compare to the UE distribution to see if we obtain the same shape and ratio as obtained in pp. It seems different, I have to check my code.

Comportement chaotique en fonction des données LHC11 que j'utilise --&gt; le facteur 2 que l'on trouve entre pp et pPb n'est certainement pas du à la physique ! Les données sont celles données par Gustavo du 29 avril 2013 et du 18 mars 2014.

#UpdatexEdistrib1905

*19/05/2014*

A cause des niveaux de trigger il faut faire attention lorsqu'on utilise les données des niveau L1 et L2 ensemble. On choisit de faire l'analyse avec les données L1(seuil de 12 GeV /c) pour le domaine en p_T^trigg de 12 à 25 GeV /c et avec les données L2 (seuil à 7 GeV /c) pour le range 10-11 GeV /c.
La stat disponible dans L2 pour 10-11 GeV /c est 10 fois plus faible que pour L1 de 12 à 25 GeV /c ----&gt; Barre d'erreur plus importante.
Les valeurs de la pureté ont été calculées par Catherine.

   * [[%ATTACHURL%/3xEFitL2_10_12.pdf][3xEFitL2_10_12.pdf]]: the three part of xE isolated photon formula

   * [[%ATTACHURL%/3xEL2_10_12.pdf][3xEL2_10_12.pdf]]: 3xEL2_10_12.pdf

   * [[%ATTACHURL%/xEPhotonL2_10_12.pdf][xEPhotonL2_10_12.pdf]]: xE for isolated photon : the fit does not converged because of the small error bars at high x_E where the distribution is negative.

Les barres d'erreurs semblent très grandes (pas trop de stat 10 fois moins pour L2 10-12 que pour L1 12-25) mais lorsqu'on fait la propagation d'une soustraction on somme en quadrature les erreurs.

Erreur dans la propagation pour les ratios GoodRuns /AllRuns et GoodRuns /BadRuns --&gt; problème réglé, nouveaux plots ici :

*15/05/2014*

Update of x_E distribution : I did a non weighted average of each bin in [12,25] GeV /c --&gt; it's not the proper way to do the analysis. One must scale the total distribution with the number of particles in 12-25 and not scale each bin distribution with number of particle in the bin.
It doesn't change a lot but it could be interesting to do the comparison between the two methods. ---&gt; !!!!!!!!!!!!!!! To do !!!!!!!!!!!!!!!

*09/05/2014*

Check if the values for left and right side UE \Delta\Phi are OK -----&gt; There is no hole for left side as confirmed by the fit

   * [[%ATTACHURL%/DeltaPhiLeftRightInitial.pdf][DeltaPhiLeftRightInitial.pdf]]: Plot the value taken by \Delta\Phi for left and right UE.

   * [[%ATTACHURL%/DeltaPhiLeftRightPositif.pdf][DeltaPhiLeftRightPositif.pdf]]: Same plot as before but add 2*Pi() if negative values of \Delta\Phi

Comparison between AllRuns data and AllGoodRuns data -----&gt; slight difference between the two datasets -&gt; see if we choose to remove others bad runs when we go back to QA

   * [[%ATTACHURL%/compareGoodAllrunsFitxE.pdf][compareGoodAllrunsFitxE.pdf]]: compareGoodAllrunsFitxE.pdf

Comparison between L1 data and L1+L2 data : L2 has 50% of L1 statistic but for the xE histograms the biggest part of the stat is below 12 GeV /c so we don't use it for the analysis.

   * [[%ATTACHURL%/CompareL1_L1L2Fit.pdf][CompareL1_L1L2Fit.pdf]]

Comparison between the analysis for \p_{T}^{trigg} \in [10,25] GeV /c and \in [12,25] GeV /c : the purity is very low for low \p_{T}^{trig} not sure this is the best option

Do the plots with merged data &lt;=&gt; LHC13d, e, f without identified bad runs from QA
there is 14 bins in p_T^trigg [12,25]

   * [[%ATTACHURL%/3xE.pdf][3xE.pdf]]: three part of the equation for x_E distribution for isolated photon ----&gt; Check if our x_E distribution has sense and do the ratio over f(x_E^UE) to be sure that the UE is negligible for high x_E where we don't have information on it

   * [[%ATTACHURL%/CompareUELeftRight.pdf][CompareUELeftRight.pdf]]: UE right and left comparison du to weird value in analysis code ----&gt; we want to be sure we can use this for now

   * [[%ATTACHURL%/xEPhoton.pdf][xEPhoton.pdf]]: x_E distribution for isolated photon with 12 bins in p_T^trigg (means still fake errors for two bins) ----&gt; Maybe it will be interesting to search for a good binning (i.e minimise the error bars)

When we look carefully at the x_E distribution (i.e TH2F in the plots analysis) we see that it would be great to perform the analysis from 10 Gev/c to 25 Gev/c ------&gt; we need L2 data
PRELIMINARY plots

   * [[%ATTACHURL%/3xE1_25.pdf][3xE1_25.pdf]]: the three part of the isolated photon x_E distribution formula p_T^trigg in [10,25] GeV /c ----&gt; fake value of the purity for the 2 first bins

   * [[%ATTACHURL%/xEPhoton10_25.pdf][xEPhoton10_25.pdf]]: we clearly see that we reach the high x_E region with more statistic here ! See if always true with good values of the purity

For both we have negative values for certain bins -&gt; What do we do ? TMath::Abs() ?

*23/04/2014*

Compare the three data periods ----&gt; we want to merge data
Two different plots : one with 14 bins in p_T^trigg (still a fake error on two bins for purity), and one with 1 bin in p_T^trigg
