Hi Matt,

I asked Pythia authors about the difference in jet cross-section we have seen between Pythia 6 and Pythia 8. I got a first response from Peter Skands, he replied to me six days ago, but his email ended up in my junk box until I realized it today. He seems to be interested in this issue. You can find more discussion at the link below. I will let you know if we have reached a meaningful conclusion.

Thanks,

Zilong

Hi all,

We will have our regular PYTHIA 8 tune meeting tomorrow (7/14) at 3 PM BNL time. I have copied the connection details below.

For agenda items, so far I plan on showing the tune results using updated NNPDFs/CDF data/ISR parameters. If there are others please let me know.

Cheers,
Matt
