IMPORTANT: The cross-section values listed in the table are largely still for the 2 TeV Tevatron.     The tbj and tb NLO's are for the 1.96 TeV Tevatron and are taken from Zack Sullivan's talk, though I used the top mass for renormalization and factorization scales (not what he used). The ttx NLO CS needs to be updated for 1.96.

Normalizations (divide by 9 for W BR, divide by 2 for t vs. tx):
tbj: 1.98/9/2 = 0.11pb Madgraph cross-section: 0.044pb Normalization: 2.46
tb:   0.88/9/2 = 0.0488pb Madgraph cross-section: 0.0366 Normalization: 1.33
ttx:
tbj_1diag: 0.11pb Madgraph cross-section (4samples) 0.0798 Normalization: 1.37

Outstanding questions:
1. What renormalization/factorization scales to use for tbj?
2. What diagrams to include/exclude for tbj?
3. Cone size for PGS?
4. Jet eta plot for wjj.... why the abrupt change at eta==2.0?

*All values are for 2 TeV Tevatron and from hep-ph/9807340 unless otherwise noted.
**hep-ph/9604223
***hep-ph/9705398 - Both the LO and NLO tbj CS's are the most likely to be out-of-date. tbj used to be 2.44pb, but there was a problem in the PDFs. After that was corrected, the CS was 2.12pb, but that was for the 2 TeV Tevatron. Now we're at 1.98 pb.
