for GEANT plots:

plotting variable (gpt*gpt), with rapidity cut, y > -1, y < 1

 

for reco plots:

plotting variable (pt*pt), with cuts as follows:

abs(pPairs.pionH.yRap)>0.1 && abs(pPairs.pionH.yRap)<1.0 && qTot == 0 && nTot==2 && pPairs.pionH.mInv > 0.55 && pPairs.pionH.mInv <0.92 && nPrim==2 && pPairs.pCharge == 0 && pPairs.tr1.nHits >= 13 && pPairs.tr2.nHits >= 13 && abs(rVertex)<8 && abs(zVertex)<50
