| Sumario: | A measurement of the splitting scales occuring in the k<sub>t</sub> jet-clustering algorithm is presented for final states containing a Z boson. The measurement is done using 20.2 fb<sup>−1</sup> of 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 p<sub>T</sub> region 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. |
