Isolation of Electrons and Photons on the Second Level Trigger

In this note the possible gain in jet rejection in the second levele/gamma trigger is studied by applying isolation cuts. So far,isolation of electromagnetic showers is only required in the firstlevel trigger. On the second level trigger the information of allcalorimeter cells is available. Hence, i...

description In this note the possible gain in jet rejection in the second levele/gamma trigger is studied by applying isolation cuts. So far,isolation of electromagnetic showers is only required in the firstlevel trigger. On the second level trigger the information of allcalorimeter cells is available. Hence, improved isolation criteriacompared to the first level trigger can be applied. To minimise datatrnasfer isolation is studied in a maximal window of (deta x dphi) = (0.4 x 0.4) around the shower core.
