Since
in the experiments, efficiency and purity of detector plays a big role
in results, so we simulate effect of efficiency and purity on final
results in our analysis. we asume efficeincy & purity varies as
gaussian
with a mean and sigma. These mean and sigma differs for postive and
negative particles.
Now we have taken following case shown in table
and calculate values of D's. Plot values of D's
Vs N_sub.

red line = First set
green line = Second set
pink line = Third Set
example:
effS= gRandom->Gaus(MeanS, Sigma);
effB= gRandom->Gaus(MeanB, Sigma);
puritySpos= gRandom->Gaus(MeanS
,Sigma);
puritySneg=
gRandom->Gaus(MeanS, Sigma);
purityBpos=
gRandom->Gaus(MeanB, Sigma);
purityBneg=
gRandom->Gaus(MeanB, Sigma);
TOT_Baryon = tot_baryon*effB +
(tot_impurityPos*purityBpos-tot_impurityNeg*purityBneg);
Float_t TOT_Strange =
tot_strange*effS +
(tot_impurityPos*puritySpos-tot_impurityNeg*puritySneg);
where
tot_impurityPos = all postive pions & tot_impurityNeg = all negative
pions, which we
consider as impuirty
