Description
We will discuss the status of CoGeNT and C-4, searches for low-mass WIMPs below 10 GeV/c^2. The performance of the first C-4 detector will be presented and compared to the previous generation of p-type point contact germanium detectors, employed in CoGeNT. First results from a sophisticated energy-time analysis of the 3.4 year CoGeNT dataset will be shown. This analysis considers not only the possibility of a WIMP signal from standard and non-standard galactic haloes, but also signatures from axion-like particles, as well as other scenarios able to account for a low-significance annual modulation.
We will also discuss the ongoing status of PICO-250l, a large bubble chamber containing C3F8 or CF3I, to be installed at SNOLAB. PICO is the merger of the PICASSO and COUPP collaborations. Ongoing related activities at SNOLAB (PICO-2l and COUPP-60) will be presented.
