Conformal symmetry has recently been found to have unexpected applications in quantum chromodynamics (QCD) at high energy, particularly in the calculation of energy flow correlations at the Large Hadron Collider (LHC) and other collider experiments. This builds on previous studies of using collider observables to constrain conformal field theory, known as conformal collider physics. This talk provides a comprehensive review of the progress made in this field, highlighting the power of symmetry in interpreting experimental results and the implications for our understanding of QCD at high energies. The insights gained from these findings have led to the discovery of new experimental phenomena, which demand a deeper understanding of QCD in Minkowski spacetime.
