Event genera<strong>to</strong>rs<br />
At high energies many gluons are radiated. Then one needs <strong>to</strong> include<br />
high orders in αs for which complete, IR regulated matrix elements are not<br />
available.<br />
⇒ Shower Monte Carlo methods:<br />
Include only the log enhanced terms of tree digrams (no loops)<br />
Use phenomenological hadronization model for Q < µ.<br />
This gives approximate results for hadron<br />
distributions in the final state.<br />
The reliability is tested by including<br />
next-<strong>to</strong>-leading logarithms and comparing<br />
several hadronization models.<br />
