Run-11 Transverse Jets: R050 Results

Here, I post updated results using the new cone radius of R = 0.5. Results are still preliminary in a few ways:

  • Verify three-Gaussian fits to nσ(π) distributions are robust
  • Revisit trigger-bias estimates
  • Still need maximized projections from the Torino group for Collins-like

From discussions with the jet group, the plan would be to include Figs. 1-3 in the paper and convert Figs. 4-5 to a single table. After observing the large Collins asymmetry, the high-pT Collins vs. jT will be promoted to a figure.

Figure 1: Inclusive Jet Azimuthal Asymmetry

Could think about quoting mean η rather than range of η. Also, I will check with Koichi Kanazawa for updated theory curves.

Figure 2: Collins(-like) Asymmetry vs. z

Aside from that listed above these should be close to ready.

Figure 3: Collins-like Asymmetry vs. z for Low pT, jet

To do:

  • Try to obtain theoretical predition for maximized scenario
  • Verify trigger bias estimate

Figure 4: Collins(-like) Asymmetry vs. pT

To do:

  • Verify trigger bias estimate (currently using what was determined for Inclusive jet asymmetry vs. pT

Figure 5: Collins-like Asymmetry vs. pT, jet for Low z

To do:

  • Try to obtain theoretical predition for maximized scenario (should be ~2% or so)
  • Verify trigger bias estimate (currently using what was determined for Inclusive jet asymmetry vs. pT)

Figure 6: Collins Asymmetry vs. jT in Bins of z and pT, jet

To do:

  • Recalculate for new cuts (aside from high-pT)
  • Real average z for each bin (aside from high-pT, currently just the center of the detector-z bin)
  • See if I can reduce "horizontal" uncertainty on first jT bin of low-pT, z ~ 0.25 and next-to-last jT bin of low-pT, z ~ 0.55
  • Verify trigger bias estimate (currently using what was determined for Inclusive jet asymmetry vs. pT

Figure 7: Collins-like Asymmetry vs. jT in Bins of z and pT, jet

To do:

  • Recalculate for new hadron radius cut
  • Real average z for each bin (currently just the center of the detector-z bin)
  • Decide what to do about lowest-jT π+ point of high-pT, z ~ 0.15, η < 0 bin (-0.074±0.026) -- Plan to drop these bins!
  • See if I can reduce "horizontal" uncertainty on first jT bin of low-pT, z ~ 0.25 and next-to-last jT bin of low-pT, z ~ 0.55
  • Verify trigger bias estimate (currently using what was determined for Inclusive jet asymmetry vs. pT
