Axions are in WIMPS are out!
"Axions are even trickier than WIMPs. They’re theorized to be extremely light—a millionth of an electronvolt or so, about a trillion times lighter than the already tiny electron—making them next to impossible to produce or study in a traditional particle physics experiment. ... That means they exist all around us, as many as 10 trillion per cubic centimeter, waiting to be detected. ... In the presence of an electromagnetic field, they should sometimes spontaneously convert to easily detectable photons."
