"Big bang nucleosynthesis as a probe of new physics"

Sougata Ganguly (Institute for Basic Science -IBS-, South Korea)

Abstract: The remarkable agreement between the observed light-element abundances and the predictions of big bang nucleosynthesis (BBN)
makes BBN a powerful probe of physics beyond the Standard Model (BSM). In this talk, I will present the BBN constraints on a specific BSM particle,
the Majoron, and discuss its cosmological implications. I will also highlight the caveats of the standard BBN scenario in light of the long-standing
cosmological lithium problem and briefly outline a possible solution.
