A brief summary of the numbers used in obtaining present preliminary E789 D results - MJL, 11/9/92 Be Au ------------ ------------- protons/me3ic 71x10^6 6.24x10^6 (p.247 Log VI) (p.252 Log VI) rhotgt 1.848 gm/cm^2 19.32 gm/cm^2 xtgt(1.5mm) 1.852x10^22 nuclei/cm^2 8.857x10^21 nuclei/cm^2 eff-vtx(Kpi) .0909 .101 (from monte carlo/analysis) acceptance .00293 .00312 (differnces due to beam-x on target) (used Kodama et al kinematic distributions) eff-proc .86 (from Ron's simulation and monte carlo) eff-trig .39 (.9 hodo x .43 calorimeter+susd+etc) decay .69 (hand calculation; needs full monte carlo) amonsb 8.05x10^5 8.76x105 KPi counts 281+311 202+221 (asym. gaussian and constraint between K-Pi+ and K=Pi- only within each of K-Pi+ or K+Pi- mass id plots) Resulting numbers: sig(K-Pi+K+p-) ~= 21.5+/-1.4ub or 27.6+/-1.8 (for .56 or .43 calor+susd+.. effs) alpha ~= .84+/-.02 (for standard cuts; see previous note for other lifetime cuts) assym(K-Pi+/K+Pi-,Be) ~= .90+/-.08 BR(PiPi)/BR(KPi) ~= .036+/-.006 (fitting needs work yet)
