Calibration of the CMS Electromagnetic Calorimeter with $\sqrt{s}$ = 7 TeV LHC collisions data
The $\sqrt{s}$ = 7 TeV LHC collisions recorded with the CMS detector have been used to perform a channel-by-channel calibration of the electromagnetic calorimeter (ECAL). With 2010 data, decays of $\pi^0$ and $\eta$ into two photons as well as the azimuthal symmetry of the average energy deposition...

Sumario: | The $\sqrt{s}$ = 7 TeV LHC collisions recorded with the CMS detector have been used to perform a channel-by-channel calibration of the electromagnetic calorimeter (ECAL). With
2010 data, decays of $\pi^0$ and $\eta$ into two photons as well as
the azimuthal symmetry of the average energy deposition at a
given pseudorapidity are used to equalize the response of the
individual channels. Based on 36 pb$^{-1}$ of collected luminosity,
results will be shown for each method and for the combination.
Finally, the energy scale of the ECAL has been investigated and
comparison with the simulation predictions will be presented. |
