Proposal for a pi0 trigger at level-0
2000-024 This note shows the possibility to trigger on neutral pions at level 0 in the electromagnetic calorimeter. It describes a pi0 trigger within the framework of the 2x2 trigger described in LHCb notes 2000-010, 99-053, 99-017, 99-013 and 99-007. The trigger consists in computing the invariant...

description | 2000-024 This note shows the possibility to trigger on neutral pions at level 0 in the electromagnetic calorimeter. It describes a pi0 trigger within the framework of the 2x2 trigger described in LHCb notes 2000-010, 99-053, 99-017, 99-013 and 99-007. The trigger consists in computing the invariant mass of photon clusters hitting adjacent front-end blocks. Its efficiency is computed for 2 decay channels : Bd -> pi+ pi- pi° and B+->K+ pi°. |
