Add to Calendar 11/30/2018 12:00 pm 11/30/2018 America/Chicago High Energy Phenomenology Seminar: Lindsay Forestell (UBC) "Big Bang Nucleosynthesis and the Dark Side" DESCRIPTION:

The consistency of standard Big Bang Nucleosynthesis (BBN) with the lambda-CDM model of the Universe is a remarkable success. Because it is so consistent, not only is it the earliest test of lambda-CDM, but any perturbations during this epoch will be extremely sensitive to changes in BBN. Thus, it can be used as an excellent tool to probe new physics. Here I will discuss the changes to standard BBN analysis that must be made to use this tool at low mass scales. Although BBN has been extensively covered at high masses, lower mass theories are beginning to become more popular, and it is thus worth extending the range in which we can accurately use BBN as a probe. I will also provide an example in which we utilize BBN limits (and others) to constrain a particular model of a new dark gauge force.
