[Rivet] CMS ridge

[Holger Schulz]

Hi Xavier,

sounds interesting. Google tells me that some students used CMS open
data to rediscover
the ridge --- do you think it would be feasible to do the BG subtraction
in that fashion, too?

Thanks,
Holger

I/We had a simplified version with mixing the 10 previous events for the first pp paper I think but no idea after all this time where I did put it.  What I did with was only MC and without fixing the normalisation, so without comparison to real data in fact. I am cc’ing some relevant people from our heavy ion group to see if they would have interest
