Blessed plots for the subcluster analysis (update)

Subclusters are observed in high Et jets produced in proton-antiproton collisions at a center-of-mass energy of 1800 GeV. No evidence for subclusters in low Et jets is also presented. The properties of the observed jet subclusters are compared with the predictions from a QCD parton shower Monte Carlo program.

• scl_eta_phi_kta_pub.ps---Distributions of tracks in a jet are displayed in eta - phi space. The transverse momentum of the jet is approximately 160 GeV/c. We display 4 typical jets. Tracks associated with a subcluster are indicated by the same symbol. The subclusters have been determined using the kt algorithm. The jet cone radius is 0.7.
• minj_scl_eta_phi_kta_pub.ps---Distributions of tracks in a jet are displayed in eta - phi space. The transverse momentum of the jet is approximately 9 GeV/c. We display 4 typical jets. Tracks associated with a subcluster are indicated by the same symbol. The subclusters have been determined using the kt algorithm. The jet cone radius is 0.7.
• avrms_ptsub_kta_jsch.ps---The RMS distribution of tracks in a subcluster is plotted as a function of the transverse momentum Pt(sub) of the subcluster for high Et jets using Kt algorithm.
• avrms_ptsub_kta_jsch_core_noncore.ps---The RMS distribution of tracks in a subcluster is plotted as a function of the transverse momentum Pt(sub) of the subcluster for high Et jets using Kt algorithm. The subclusters in core and non-core of jet are compared.
