Search for the Rare Decay $K_L \to \pi^0 \pi^0 \mu^+ \mu^-$

Abstract

This thesis describes the search for K L → π 0 π 0 µ + µ − , which was conducted using data collected by the KTeV Experiment at Fermi National Accelerator Laboratory in Batavia, Illinois. Although this decay mode is possible within the Standard Model,
