Machine learning method for enforcing variable independence in background estimation with LHC data: ABCDisCoTEC

Aram Hayrapetyan, Vladimir Makarenko, Armen Tumasyan, Wolfgang Adam et autres

Abstract A novel solution is presented for the problem of estimating the backgrounds of a signal search using observed data while simultaneously maximizing the sensitivity of the search to the signal. The ‘ABCD method’ provides a reliable framework for background estimation by …

Resolution of the ATLAS muon spectrometer monitored drift tubes in LHC Run 2

Georges Aad, Abbott, Brad, D. C. Abbott, Abdinov, Ovsat et autres

The momentum measurement capability of the ATLAS muon spectrometer relies fundamentally on the intrinsic single-hit spatial resolution of the monitored drift tube precision tracking chambers.Optimal resolution is achieved with a dedicated calibration program that addresses the specific operating conditions of the 354 …
