摘要：

The CMS collaboration has made some of their data public, making it possible for external users to perform physics analysis using real data. In this work, we report the measurement of jet properties such as fragmentation function, and the average multiplicity distribution of leptons and charged hadrons within the jets, all of them produced in pp collisions at root s = 7 TeV. We show that by implementing high energy cuts, the uncorrected experimental data approaches the behavior of corrected data, facilitating the use of open-data for simple analysis. The analysis is restricted in pseudorapidity and energy of the jets to: |eta(Jet)| < 2.1 and E-Jet > 120 GeV respectively. For the study we used the anti - K-T algorithm applied to four samples of 2011 CMS open-data, to explore the possible differences obtained by using different trigger conditions, and the results are compared with predictions from the PYTHIA 8 event generator.
