lambda_analysis Nov7~ weekly meeting NOV07 2008 GHOST CUTの変更 same / opposite charge pair • ghost cut – (pi+)-(pi+), (pi-)-(pi-)でのghost pair cut – p-p, (anti-p)-(anti-p)のpairはyieldが少ないため ghost cutをしない • TOF intruder cut – (anti-p)-(pi+), (p)-(pi-)でのintruder cut – pionのみreject • mixではintruder cutのみを行う WITH KINEMATICS CUT mass distribution (centrality, pT) • lambda central peripheral pT mass distribution (centrality, pT) • lambda central peripheral pT mass distribution (centrality, pT) • anti-lambda central peripheral pT mass distribution (centrality, pT) • anti-lambda central peripheral pT 問題 • mass peakの左側でreal/mixが合っていない – 無視してよいレベルか？
