What Does PQCD Stand For?

PQCD stands for Perturbative Quantum Chromodynamics

PQCD, or Perturbative Quantum Chromodynamics, is a theoretical framework within quantum field theory that describes the strong interactions between quarks and gluons. It employs perturbation theory to calculate the properties and behaviors of these fundamental particles by analyzing their interactions at high energies where the coupling strength is small. PQCD is instrumental in predicting outcomes in high-energy particle collisions, such as those observed in particle accelerators, and plays a vital role in advancing our understanding of the fundamental forces governing particle physics.
