Analyses Near GPC
The following is a list and description of analyses which are likely to request a GPC within the next 6-12 months.
2011 IFF at 500 GeV
This analysis utilizes the same data set (2011 p+p at 500GeV) as the 2011 Collins measurement, already in GPC. The data are well-understood; and the analysis is quite mature, having already completed a PWGC preview. The largest remaining analysis-related issue is the pion contamination estimate, an issue raised during the preview. The question is also relevant for the 2011 Collins result, and a path forward has been developed. The methodology has been presented multiple times to the Spin-PWG and in Jet-finding meetings. The preliminary results from this investigation have largely confirmed the existing estimates for the high-pT data (the data with greatest impact) with only lower-momentum tracks requiring a change. These changes will not affect the message or impact of the results.
The most complicated factor for the 2011 IFF analysis is that the lead analyst, Mike Skoby, has moved on from his postdoc position at IU. Nevertheless, the IFF asymmetries are also being analyzed in the 2012 dataset and remain a high priority for the 2015 and (requested) 2017 datasets. So, the 2011 analysis will not be abandoned and the expertise is in-place to bring the 2011 result to final status. Assuming Mike’s continued involvement, we estimate a GPC request within 2-3 months.
Forward Neutral Pion Longitudinal Double-spin Asymmetries at 500 GeV
This analysis utilizes a combination of the 2012 and 2013 longitudinal-spin datasets at 500 GeV. It represents the first opportunity for a publication from the large 2013 dataset. The analysis is nearing completion. Weekly presentations are given to the FMS group, typically by Chris Dilks from PSU. The final major tasks needed are to finalize systematics related to luminosity, polarization, and energy-scale. Last week, Chris Dilks presented to the FMS group an update of the systematic from residual transverse polarization. The conclusion was that this would be a negligible-to-subdominant systematic uncertainty compared to that from the relative luminosity. This presentation suggested that analysis of these uncertainties are nearly complete. The largest of the remaining task, then, is quantifying energy-scale-related uncertainties, e.g. gain calibrations. The preliminary result handled these in a very simplistic way, and that needs to be addressed before the GPC is requested. We estimate this will take between a few weeks and a month, depending on the results of the study. Since this result combines two different datasets, the systematics study will have to be performed separately for each dataset, to account for year-to-year difference in detector performance. While this may cause a slight delay in the time to completion, we do not anticipate significant complications.
The forward ALL analysis has not had a PWGC preview. The PAs would like to complete the aforementioned analysis tasks before requesting such a meeting. Stephen Trentalange has written a paper draft that has been circulated to the FMS group. The target journal is likely to be PRD-Rapid Communication. The FMS group has also been working to finalize theory predictions, necessary for the paper. These appear to be in good shape and should not be an obstacle for moving the paper forward. We estimate that a PWGC preview will be requested in 1-2 months.
Other Active Analyses
The following is a list of analyses that, while active, we are not ready to claim near to a GPC. In many cases, the analyses are mature but lack a significant undertaking, e.g. a large simulation sample. This list should not be interpreted as a critique of the effort or priority of these analyses. It is simply our best assessment of the current status, at this time, something that is undoubtedly subject to change.
2009 Inclusive Jet Cross Section
This analysis has already had a PWGC preview and is quite mature. Its largest obstacle is that the lead analyst, Xuan Li, has moved on from her position at Temple (currently at LANL). Due in part to this, we have not had as frequent analysis updates for this result, though one is scheduled for the collaboration meeting.
2011-2013 W Cross Section Ratio
This analysis has not yet had a PWGC preview. The biggest obstacle, as we see it, is the 2013 BEMC calibration, which is needed for this result. We have had a recent update on the calibration; and we are hopeful that a path forward can be established, soon. There will also be further dedicated discussion on this at the collaboration meeting.
2011 Forward Jet-like Transverse Single-spin Asymmetries at 500 GeV
This analysis is another that is quite mature, but has not had a PWGC preview. The biggest remaining obstacle is a large simulation sample. This has been actively discussed in the FMS group, and they are nearing a completed proposal. The proposal will then need to be discussed in the full Spin-PWG.
2012 Collins Asymmetries at 200 GeV
The 2012 Collins analysis is quite mature but not ready for PWGC preview. The largest remaining obstacles are the aforementioned pion contamination estimates and a large simulation sample. The proposal for this sample has been vetted by the Spin-PWG and the request is in the queue.
2012 IFF at 200 GeV
The 2012 IFF is largely in the same position as the Collins result.
