ATLAS calorimeter capabilities for B-Physics studies: the Bs->J/Psi Eta example

This work presents an example of the utilisation of ATLAS calorimeters for B-physics analysis. We show that, using ATLAS electromagnetic calorimeter and appropriate cuts, a 2.3% eta reconstruction efficiency could be reached in the Eta->2Photons channel with a background rate of 24%. It enables t...

description This work presents an example of the utilisation of ATLAS calorimeters for B-physics analysis. We show that, using ATLAS electromagnetic calorimeter and appropriate cuts, a 2.3% eta reconstruction efficiency could be reached in the Eta->2Photons channel with a background rate of 24%. It enables the extension of ATLAS B-physics program to such interesting channels as Bs->J/psi eta, and demonstrates that ATLAS calorimeters are performant for soft-particles measurement.
