The MCFM program is a parton-level event integrator that calculates various processes, including those involving W, Z, Higgs bosons, and heavy quarks, at next-to-leading order (NLO). Version 5.8 of MCFM includes new processes such as Higgs boson production in association with two jets and top quark pair production with decay. These processes are important for understanding Higgs boson production and top quark interactions at the Tevatron and the LHC. The Higgs + 2 jet process is calculated using an effective Lagrangian that includes spin correlations. The results are based on analytic calculations of one-loop amplitudes, which improve the speed of the code. The Higgs + 2 jet cross section is important at both the Tevatron and the LHC. The Tevatron can provide important information on processes initiated by quark-antiquark collisions, and it may have a competitive advantage over the LHC for these processes. Top quark pair production with decay is another new process included in MCFM. The spin correlations in the decay are important for understanding the angular separation of the two charged leptons from top decay. The Tevatron may still have a competitive advantage for these processes even with a higher luminosity at the LHC. The Tevatron's parton luminosities are compared to those of the LHC. The Tevatron has a competitive advantage for processes initiated by quark-antiquark collisions. If the Tevatron runs until it accumulates 16 fb⁻¹ of luminosity, it could provide 3σ evidence for the standard model Higgs boson in the mass range 100 < m_H < 180 GeV. This would complement information from the LHC on the Higgs boson decay into γγ. In conclusion, MCFM has been updated to include new processes that are important for understanding Higgs boson and top quark interactions at the Tevatron and the LHC. The Tevatron can provide important information on certain processes, even with a lower luminosity than the LHC.The MCFM program is a parton-level event integrator that calculates various processes, including those involving W, Z, Higgs bosons, and heavy quarks, at next-to-leading order (NLO).
