Here is the homework from Dan:
During class, you worked toward producing a code that could calculate the thermal relic abundance of a stable, weakly-interacting particle. Finish that code on your own, and plot the freeze-out (co-moving number density vs temperature), for a 100 GeV particle, with a self-annihilation cross section of 3x10^-26 cm^3/s. Then, take this calculation one step further, and consider a scenario in which the particle decays after freezing out, into a 50 GeV particle. Also assume that the 50 GeV particle has an annihilation cross section of 6x10^-26 cm^3/s. What is the resulting abundance of the 50 GeV particle (assuming that it is stable)?
Summarize the findings from the code you started developing in class, and what is additional requested here, in a few pages document, and send to Dan Hooper <dhooper@fnal.gov> , with clear subject : "take home exam, Phd School , Copenhagen, your_name"
