Learn about Effective Field Theory in this comprehensive lecture from the ICTP-SAIFR/ExoHad School on Few-Body Physics: Nuclear Physics from QCD series. Delivered by André Walker-Loud from Lawrence Berkeley Lab, USA, explore fundamental concepts of Effective Field Theory and its applications in nuclear physics. Part of a specialized school program focusing on the intersection of quantum chromodynamics (QCD) and nuclear physics, gain insights into how theoretical frameworks help understand complex nuclear systems and interactions.
