The article titled “Energy Calibration of b-quark jets with Z->bb decays at the Tevatron collider” has passed the review stage and will appear quite soon on Nuclear Instruments and Methods in Physics Research A.

So what is the news, you might well ask. The paper was already made available in the ArXiv almost one year ago (and I wrote about the underlying story of a ten-year-long analysis in length). True. But seeing the proofread version, in NIM style, was a pleasant feeling last week, when I gave a last look at the text and spotted a few inaccuracies left over to correct. The paper amounts to 14 pages in NIMA double-column format. It features eight figures and five neat tables. Here is the abstract, for those of you who missed it the other time:

The energy measurement of jets produced by b quarks at hadron colliders suffers from biases due to the peculiarities of the hadronization and decay of the originating B hadron. The impact of these effects can be estimated by reconstructing the mass of Z boson decays into pairs of b-quark jets. From a sample of of data collected by the CDF experiment in 1.96 TeV proton-antiproton collisions at the Tevatron collider, we show how the Z signal can be identified and measured. Using the reconstructed mass of Z candidates we determine the energy calibration of b-quark jets with a precision better than 2%. This measurement allows a reduction of one of the dominant sources of uncertainty in analyses based on high transverse momentum b-quark jets. We also determine, as a cross-check of our analysis, the Z boson cross-section in hadronic collisions using the b-antib final state as .

Now, for the subject of this post: If you want to cite this paper (please do) I can already provide you with a temporary reference:
