Accidentals rate vs running period • Accidental rate : • - P1A,P2A,P1Atw,P2Atw • - comparison MC vs Data • - with/without corrections • Corrections table along the running periods S.Miscetti MC meeting 22-Dec-2004 S.Miscetti
Identification of the rate problem ?? The problem of P1A is related to the fact that in BGG files there is always at least one accidental hit which is a condition mostly satisfied in 2001 (testing sample) Not at all in 2002! The rate problem can be partially fixed by measuring P1A for the whole 2001-2002 period and scaling it whenever P1A < 100% S.Miscetti

Prob.Acci (corrected) vs run period (2001) Data • Bins of 10 pb-1 • All MC numbers • corrected by the • Data/MC ratio • of PA(ge 1) to take • into account the • case with no hits • in the selbkg file. MC
