The Large Hadron Collider (LHC) at CERN, along with its upcoming high-luminosity upgrade (HL-LHC), will provide a vast amount of high-energy data of outstanding quality. To fully leverage this experimental precision, theoretical predictions must reach a comparable level of accuracy. This is essential not only to impose stringent constraints on the Standard Model (SM), but also to explore uncharted domains, such as the Higgs potential, and to search for signs of new physics. Future colliders will likewise require highly-accurate theoretical inputs to achieve their ambitious physics goals. The Electron-Ion Collider at Brookhaven National Laboratory will serve as a cutting-edge facility for studies in quantum chromodynamics (QCD) and for probing the internal structure of hadrons. Furthermore, the proposed Future Circular Collider (FCC) at CERN is envisioned as the next-generation facility for exploring physics beyond the Standard Model, through both direct and indirect searches. In this talk, I will highlight a selection of my contributions to the precision challenge at the LHC and future colliders. These include QCD predictions for processes involving identified light and heavy hadrons (from the fragmentation of charm and bottom quarks), as well as fixed-order calculations at next-to-next-to-leading order (NNLO) and beyond, and their matching to Monte Carlo parton showers. I will also outline possible future research directions within the community’s ongoing effort to achieve percent-level precision.
