Example : H2-1 .AND.[ (H2-4.or.H2-5.or. .... .or.H2-13) .or. (H2-21.or. ... .or.H2-29) ] H2-2 .AND.[ (H2-5.or.H2-6.or. .... .or.H2-14) .or. (H2-22.or. ... .or.H2-30) ] etc... If at least one of the above conditions is satisfied the H2_logic is ON and the event is rejected (we use this logic as a VETO) -------------------- KIN2B ----------------------------------------------- KIN2B is a "Matrix of coincidences among bundles" based upon the PhiPhi---> 4K kinematic (this logic has been studied with Montecarlo simulation) ---------------------- H2_CLUSTER -------------------------------------- It's a logic based on three different types of H2 multiplicities. The first (NH2) is the usual number of H2 elements that are hit. The second type (NH2_CLUST) is a "H2 cluster multiplicity", i.e. it counts one if there is one group of (at least) two adjacent H2 elements on, two if there are two groups of adjacent elements etc... The third type (H2_ALTCLUST ) counts the number of clusters of alternated elements, i.e., it counts one if, for example, H2_1 and H2_3 are hit or H2_2 and H2_4 (in general H2_i and H2_i+2). The final logics is a combination of the above sub logics, designed ad hoc to select phiphi events: H2_CLUSTER = (NH2=3).and.(NH2_CLU=1).and.(NH2_ALTCLU=0) .or. .or. (NH2=3).and.(NH2_CLU=0).and.(NH2_ALTCLU=1) .or. .or. (NH2=4).and.(NH2_CLU=2).and.(NH2_ALTCLU=0) .or. .or. (NH2=4).and.(NH2_CLU=1).and.(NH2_ALTCLU=1) .or. .or. (NH2=4).and.(NH2_CLU=0).and.(NH2_ALTCLU=2) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% For questions or comments please contact : Wander Baldini : - wander@fnal.gov - baldini@axpfe.fe.infn.it
