Photon Resolution Study: Eta and Energy Categories for Enhanced Analysis

This study focuses on resolving photon pairs by categorizing them based on η (eta) and energy. Key considerations include defining energy bins and determining eta bins for barrel and endcap divisions. The analysis explores the conversion possibilities and tagging strategies for leading and subleading photons across different η categories. It evaluates resolution parameters with and without smearing for various energy levels of the photons. This work aims to refine categories and suggest necessary adjustments to the Monte Carlo (MC) simulation size.

Presentation Transcript

  1. Categories for resolution study Categories : eta , energy , number of primary vertices , conversion should be considered Eta : barrel – endcap ? or 4 bins like [0, 0.6] , [0.6, 1.37] , [1.52, 1.81] , [1.81, 2.37] ? Energy : how to define the energy bins ?

  2. Fraction of eta division Di-photon, tagging as leading andsub-leading 4 eta bins -- [0, 0.6] , [0.6, 1.37] , [1.52, 1.81] , [1.81, 2.37] barrel / endcap If upper limit of the new MC is around 1,000,000. barrel – endcap division might be a better choice Also, do we need to tag two photons as leading and subleading in eta category ?

  3. conversion possibility in each eta bin Leading photon : subleading photon : Conversion for leading and subleading photon are more or less the same

  4. Glance on the resolution at different categories

  5. Resolution parameter comparison categorized by eta Without smearing : With smearing : B + B means: leading photon in barrel and subleading photon in barrel

  6. Resolution parameter comparison categorized by E (1) both of the two photons are in barrel low E low E smeared High E : E of leading Photon > 68 GeV , E of subleadingPhoton > 68 GeV Low E : E of leading Photon < 68 GeV , E of subleading Photon < 68 GeV High E High E smeared

  7. Resolution parameter comparison categorized by E (2) both of the two photons are in barrel and unconverted low E low E smeared High E : E of leading Photon > 68 GeV , E of subleadingPhoton > 68 GeV Low E : E of leading Photon < 68 GeV , E of subleading Photon < 68 GeV High E High E smeared

  8. next 1. Decide the categories of eta and energy ; 2. Any other category should be considered ? 3. Estimate the size of new MC asap

  9. Back up

  10. Resolution parameter comparison categorized by eta (2) Endcap + endcap is not precise enough smeared
