"The search for K L 0 -> π 0 π 0 μ + μ - and K L L -> π 0 μ + μ - "
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.
