AuAu2016 with dNdx
The fit function for the fits:
f(x) = Yπ / (√2πσ) ×
[g(μπ, σ) +
YK/Yπ × g(μπ, σ) +
YP/Yπ × g(μP, σ) +
Ye/Yπ × g(μe, σ)]
Cuts for final fits:
|y(π)| < 0.1
|Vz| < 30 cm
|vpdVz - vz| < 3 cm
Track Level:
pT >= 0.2 GeV
nHitsFit >= 15
HitsFit/nHitsPoss >= 0.52
nHitsDedx >= 15
dca <= 2.5 cm
ΔT for TOF
ΔT = TTOF - Texp;
TTOF = lengthToTOF / (βc);
Texp2 = (lengthToTOF2 / c2) * (1 + M2/pT2);
Prediction for TOF
|nσ| < 1
M2 = pT2 * (T′TOF2c2 / lengthOfTOF2 - 1);
T′TOF = Texp + RANDOM(ΔT);
Texp2 = (lengthToTOF2 / c2) * (1 + M2/pT2);
