DESCRIPTION:David Phillips\, University of Virginia\n\n Although the neut
ral kaon system has been researched many times in the \npast\, it still re
mains a vital tool for decisive studies on CP violation and \nfor probing
into new physics. The KTeV experiment has played a crucial \nrole in thes
e endeavors with an intense source of high energy kaon decays \ncoupled wi
th a high precision detector. Currently\, there's no published \ncalculat
ion inside the Standard Model for Br(K L 0 ->
π\; 0 π\; 0 μ\; + μ
\; - )\, \nalthough the decay is possible via a virtual photo
n or a 'possible' new \nneutral boson X 0 \, which was recent
ly observed by the HyperCP Experiment \nin the decay Σ\; + -> pX 0 -> p μ\; + μ\; -
. The decay K L L -> π\; 0
956\; + μ\; - is also an intriguing study s
ince it contains a direct CP \nviolating parameter. I shall report on the
progress made in analyzing \nthese two decays.\n
