π- and π- boson production are among of the most precisely analyzed processes at the LHC,
enabling applications that range from precision determinations of couplings to parton distribution
functions to particle masses. Direct measurements are meanwhile only limited by luminosity
uncertainties of about 1%. On the other hand, the required theory predictions are pushing the
boundaries of theoretical methods, with a level of sophistication reached that is setting the stage for
the HL-LHCβs demand for higher multiplicity processes at a similar level. In these proceedings we
briefly summarize recent progress in the theoretical modeling of π- and π-bosons.
