MC samples

Single top t-channel samples produced with:

• AcerMC 3.5 + Herwig, fast sim
• AcerMC 3.5 + Pythia, full sim

Atlas realease is 12.0.7.

Event selection

• 1 reconstructed lepton with Pt>30 GeV.
• At least two jets with Pt>30 GeV
• Jet multiplicity <= than 10 (for Pt>30 GeV jets)

Comparison of distributions (single top t-channel)

We shown below the comparison of some kinematical variables distributions between AcerMC+Herwig fast sim (yellow) and AcerMC+pythia full sim (blue) MC samples. All distributions are normalized to unity.
