Hello, all

  We have a few  ttbar samples (low pT and high-pT) generated with 
HERWIG++ with overplayed  pileup events (140 pileup events, 14 TeV pp 
case). The samples were generated using Delphes 3.04 (it was modified to 
make this possible).  In addition, we have posted  "signal" ttbar 
samples, i.e. before mixing with 140 pileup events.

You can find this information here:

Please  send your feedback. It would be very interesting to see the 
effect of pileup on top reconstruction and jet resolution. The samples 
are mainly needed to adjust resolution functions in Delphes3, since 
generation of large samples in this approach is not very practical due 
to large size of ROOT files

best, Sergei
