Experimental investigation of the energy dependence of the strong coupling strength

Jet-Hadron Correlations insNN=200 GeVp+p

“…In elementary collisions, jets can be reconstructed by clustering their constituents in order to determine the energy and direction of the parent parton [20][21][22]. However, full jet reconstruction in a heavy-ion environment presents large challenges due to the fluctuating underlying event from soft processes.…”

Quark-gluon jet differences inZ0decay

“…In doing this, a jet finder that was specially designed to analyze Y events outperforms the k ⊥ [7] algorithm, and by even more the JADE [6] algorithm.…”

“…According to the simulation, Y events defined in this tightlyrestricted way make up 0.88% of hadronic Z 0 decays. Other jet-finding algorithms such as JADE [6] or k ⊥ ("Durham") [7] yield similar rates and estimates for the jet axes, as will be discussed in Section 4.…”

“…It is interesting to compare with results obtained using the standard jet algorithms JADE [6] and "k ⊥ " [7]. To make the comparison, we re-analyze our events according to those schemes, choosing the resolution parameter y cut in these schemes for each event to obtain three jets.…”

Inter-string Bose-Einstein Correlations in Hadronic Z Decays using the L3 Detector at LEP

“…There are several jet clustering algorithms, e.g., the JADE [39,40] and Durham [41,42] algorithms, which are widely used in high energy physics studies. The Durham algorithm is used in this thesis.…”
