Abstract: The precision of 1% that is reached today in LHC π- and π-boson measurements is a great achievement, but also a great challenge. The reward of these measurements comes from a wealth of Standard Model precision tests and phenomenology. On the other hand, the achieved precision challenges practical calculational methods for higher order cross-sections, and even stress tests underlying concepts like factorization. In particular, perturbative third-order QCD predictions are necessary to reduce residual truncation uncertainties to the level of 1 β 2%. These developments open up a future focus on many similarly sized effects in non-perturbative proton structure and electroweak effects, for example. In these proceedings we briefly summarize our third-order QCD predictions for π- and π-boson production, which are publicly implemented in the code MCFM. We put our calculation in the broader context of current calculations and future development needs.
