SITP Wine and Cheese Seminar: Big Bang Nucleosynthesis: New Physics and New Tools

Speaker: Cara Giovanetti (NYU) In Person

Big Bang Nucleosynthesis (BBN) is a powerful tool for probing both new physics and LCDM, and complements analyses utilizing the Cosmic Microwave Background (CMB) and results from particle experiment.  I will provide two examples of BBN probes of BSM models, and show that there is still a lot to learn about BBN and new physics.  I will finally discuss the recently-released fast and differentiable BBN code LINX, which can be used to perform full BBN+CMB joint analyses at a level of sophistication that has never been achieved before.
