Connecting LHC, ILC, and Quintessence

Understand

If the cold dark matter consists of weakly interacting massive particles (WIMPs), anticipated measurements of the WIMP properties at the Large Hadron Collider (LHC) and the International Linear Collider (ILC) will provide an unprecedented experimental probe of cosmology at temperatures of order 1 GeV.

• It is worth emphasizing that the expected outcome of these tests may or may not be consistent with the picture of standard cosmology.
• For example, in kination-dominated quintessence models of dark energy, the dark matter relic abundance can be significantly enhanced compared to that obtained from freeze out in a radiation-dominated universe.
• Collider measurements then will simultaneously probe both dark matter and dark energy.
