The dangerous jet background which has large uncertainties needs to be further reduced by a factor of about 3 so that it does not dominate the irreducible background. 0000009395 00000 n Some of the more recent calorimeter implementations do in fact partially use higher granularity layers (strip detectors) to exploit these possibilities, as in the CMS pre-shower detector [3], and full three-dimensional shower reconstruction was used in the PAMELA space mission [4]. Then the shower shape is analysed with a neural net using 11 strips centered on these positions [5]. For a Higgs mass of 120 GeV, the 0s have a transverse energy of the order of 60 GeV leading to a separation between the 2 photons arising from the 0 decay of about 0.8 cm in the barrel region while it is only few milimeters in the endcaps.
