Subjet multiplicity in quark and gluon jets at D-Zero

PDF Version Also Available for Download.

Description

The authors measure the subjet multiplicity M in jets reconstructed with a successive combination type of jet algorithm (K{sub T}). They select jets with 55 < E{sub T} < 100 GeV and {vert_bar}{eta}{vert_bar} < 0.5. They compare similar samples of jets at {radical}s = 1800 and 630 GeV. The HERWIG Monte Carlo simulation predicts that 59% of the jets are gluon jets at {radical}s = 1800 GeV, and 33% at {radical} s = 630 GeV. Using this information, they extract the subjet multiplicity in quark (M{sub q}) and gluon (M{sub g}) jets. They also measure the ratio R {equivalent_to} (M{sub ... continued below
