Cuts: ( Mee(LNEL1,LNEL2) > 2.AND. EW(LNEL1)*EW(LNEL2) > 0.1) .OR. ( Mee(LNMAX1,LNMAX2) > 2.AND. EW(LNMAX1)*EW(LNMAX2) > 0.1) .OR. ( Mee(LINES1,LINES2) > 2.AND. EW(LINES1)*EW(LINES2) > 0.1) LNELx,LNMAXx,LINESx are variables in kinem.cde and the EW is stored in TRACKPAR(24,i) (elewei.FOR) Program is compiled by /code/e835code/psinc/src/trim_link_ewdst Efficiency of this selection (starting from gold data) on Jpsi is 94% Background : etacp < 0.9 nb (Mee>2 GeV) etac ~ 1 nb
