Abstract

A measurement of the splitting scales occuring in the ktjet-clustering algorithm is presented for final states containing a Z boson. The measurement is done using 20.2 fbâ 1of proton-proton collision data collected at a centre-of-mass energy of s=8 TeV by the ATLAS experiment at the LHC in 2012. The measurement is based on chargedparticle track information, which is measured with excellent precision in the pTregion relevant for the transition between the perturbative and the non-perturbative regimes. The data distributions are corrected for detector effects, and are found to deviate from state-of-the-art predictions in various regions of the observables.[Figure not available: see fulltext.].
