Boosted Regression Tree Based Invariant Mass Reconstruction of $\tau$ Lepton Pairs at ATLAS

Boosted regression trees were tested as an alternative to the currently used invariant mass reconstruction algorithms for hadronically decaying tau lepton pairs. In particular, focus was placed on the mass range necessary for accurate measurement of the Higgs Boson. Over this range, boosted regressi...

description Boosted regression trees were tested as an alternative to the currently used invariant mass reconstruction algorithms for hadronically decaying tau lepton pairs. In particular, focus was placed on the mass range necessary for accurate measurement of the Higgs Boson. Over this range, boosted regression trees showed performance comparable to that of the currently used algorithms, but using only a small fraction of computational resources for evaluation.
