Probe Rjets in different phase space volume/regions
Jet kinematic variable
*This is just an illustration of what the final measurement
must look like.
-Data points are pure fiction
-Theoretical prediction made from ppbar at √s=1.96TeV
Excess of W+jets or of Z+jets candidate events
Good agreement indicate a good understanding of the
more fundamental featured of analysis, preparing for
more complex studies
expertise in the estimate of such quantities, so don’t want to by-pass
chance of testing it…
Oxford group interest converged in a Rjets measurements
Low sensitivity to new physics
I would propose to choose jets selections of the jets+met analysis
A lot of work has been made in this group on that!!!
