SUMMARY:Dark Matter Results from XENON100 and Scintillation Response o
f LXe to Low Energy Particles\, NPAC (Nuclear/Particle/Astro/Cosmo) Fo
rum\, Kyungeun Lim\, Columbia University
DESCRIPTION:XENON100 is a dual-phase (liquid-gas) time projection cham
ber (TPC) containing a total of 161 kg of LXe with a 62 kg WIMP target
mass\, built with radiopure materials to achieve an ultra-low electro
magnetic background and operated at the Laboratori Nazionali del Gran
Sasso in Italy. Data from the XENON100 experiment have resulted in the
most stringent limits on the spin-independent elastic WIMP-nucleon cr
oss sections for WIMP masses above 8 GeV/c^2.
\n
\nI will pres
ent the experiment and its latest dark matter search results. I will a
lso discuss a dedicated test facility built and operated at Columbia U
niversity to measure with high precision the scintillation response of
LXe to low-energy electrons and nuclear recoils of interest to dark m
atter direct detection experiments like XENON.
