Changes in Dark Matter Properties After Freeze-Out

The properties of the dark matter that determine its thermal relic abundance can be very different from the dark matter properties today. We investigate this possibility by coupling a dark matter sector to a scalar that undergoes a phase transition after the dark matter freezes out. If the value of Omega_DM h^2 calculated from parameters measured at colliders and by direct and indirect detection experiments does not match the astrophysically observed value, a novel cosmology of this type could provide the explanation. This mechanism also has the potential to account for the "boost factor" required to explain the PAMELA data.Comment: 5 pages; v2: Fixed minor typo, added short discussion of application to PAMELA and appropriate references, results unchange

Kansas Oil and Gas Update

Kansas courts continue to address foundational oil & gas law issues in unique and complex factual contexts. The report for this year again illustrates how oil and gas law principles can vary from state-tostate. This simple fact highlights why a publication like the Texas Wesleyan Law Review\u27s Annual Survey on Oil and Gas law is so helpful and important for those who practice in this area
