High-Energy Physics & RIKEN Theory Seminar
"Two Topics in Cosmoparticle Physics"
Presented by Maxim Perelstein, Cornell University
Wednesday, April 6, 2005, 1:30 pm — Small Seminar Room, Bldg. 510
My talk will be concerned with the implications of the recent precise
measurements of cosmological parameters for particle physics. First,
I will explain how the measurement of dark matter density can be used
(assuming that dark matter consists of WIMPs) to predict the rate of
anomalous missing energy events due to WIMP production at colliders.
Second, I will argue that the cosmological observations do not rule out
the sterile neutrino interpretation of the LSND experiment. I will
an explicit model of sterile neutrino masses in which the non-standard
cosmological evolution of neutrinos allows them to evade all known
The talk is based on two recent preprints, hep-ph/0403004 and
