Improving the precision of SM calculations

The quest to unravel Nature's fundamental constituents and interactions relies critically on precise theoretical predictions. They are essential for fully exploiting the potential of experiments, in particular at colliders, and provide the foundation for:

Deciphering the experimental data: Like a Rosetta Stone for particle physics, theory predictions allow us to translate raw experimental data into meaningful insights about the particles and forces governing the Universe.

Unveiling new physics: By comparing precise predictions with experimental observations, we can identify subtle discrepancies that may reveal the existence of physics beyond the Standard Model.

Refining our knowledge of fundamental constants: Accurate theoretical predictions enable us to extract precise values for the fundamental constants of nature, such as particle masses and coupling strengths.

Deepening our theoretical understanding: The pursuit of precision compels us to refine our theoretical frameworks, leading to a deeper understanding of the underlying principles governing physics.

Building on these foundations, this presentation will explore recent progress in enhancing the precision of Standard Model calculations for collider processes, driven by the ever-increasing accuracy of experimental measurements. We will focus on recent advancements in perturbative calculations, particularly within Quantum Chromodynamics (QCD), which describes the strong force governing the interactions of quarks and gluons. We will discuss some of the recent state-of-the-art results in perturbative calculations and progress in understanding the all-order structure of the quantum corrections.

Furthermore, this talk will address the ongoing challenges in achieving the required theoretical precision for current and future colliders. We will explore promising research avenues, including developing innovative calculational techniques and the crucial interplay between theory and experiment.
