SUMMARY:National Superconducting Cyclotron Laboratory Seminar
DESCRIPTION:
 Keith Olive from University of Minnesota will 
 be speaking.\n
 \n
 \n
 The semniar is titled "Big 
 Bang Nucleosynthesis - Post Planck."\n
 \n
 The abstract 
 is as follows:\n
 Big bang nucleosynthesis 
 provides a window to the physics of the universe 
 just seconds after the big bang. It predictions 
 of the light element abundances of 
 D, He-4, and Li-7 can be compared with observational 
 determinations. Over the last several 
 years, significant progress has been made in 
 the determinations of deuterium and helium 
 abundances and most importantly results from 
 Planck measurements of the microwave background 
 have provided precise values for the baryon 
 density of the universe, a key input used in 
 abundance predictions. Planck data is combined 
 with BBN to test the consistency of the Standard 
 Model. These predictions are also sensitive 
 to the conditions when the temperature 
 of the universe was ~ 1 MeV or ~ 10^10 K. Using 
 inputs from the standard model of cosmology 
 and particle physics yields excellent agreement 
 between theory and experiment. Thus deviations 
 from the standard model such as the number 
 of particle degrees of freedom (often parametrized 
 as the number of neutrino flavors) 
 can be tested.\n\n
