ABSTRACT:
Although the neutral kaon system has been researched many times in the past, it still remains a vital tool for decisive studies on CP violation and for probing into new physics. The KTeV experiment has played a crucial role in these endeavors with an intense source of high energy kaon decays coupled with a high precision detector. Currently, there's no published calculation inside the Standard Model for Br(K L 0 -> π 0 π 0 μ + μ - ), although the decay is possible via a virtual photon or a 'possible' new neutral boson X 0 , which was recently observed by the HyperCP Experiment in the decay Σ + -> pX 0 -> p μ + μ - . The decay K L L -> π 0 μ + μ - is also an intriguing study since it contains a direct CP violating parameter. I shall report on the progress made in analyzing these two decays.
