What is the current consensus on 7Li abundances and key research papers?

AI Thread Summary
Current discussions on 7Li abundances highlight a potential issue in nuclear physics as a key factor influencing observed discrepancies. Recommended papers include Steigman's work and two others discussing Big Bang Nucleosynthesis and its relation to WMAP results. The consensus remains speculative, with some skepticism about the effectiveness of proposed depletion factors from stellar processes in explaining the observed abundances. There is also a noted lack of urgency in the scientific community for further research on this topic. Overall, the conversation reflects ongoing uncertainty and the need for deeper exploration into 7Li abundance issues.

What are a couple of recommended papers on 7Li abundances? I have had a quick look at Steigman, and he seems to conclude that the problem might well be in the nuclear physics. What is the current consensus?

Cheers

Inhomogeneous Big Bang Nucleosynthesis Revisited

Thanks, Chronos. This paper seems to get 7Li concordance (for WMAP3) with a "depletion factor for stellar processes". That doesn't sound very convincing to me...unless we expect a large depletion factor to arise this way?

:smile:
 
Yep, it wasn't terribly convincing to me either Kea. Hence, 'speculative' remains the word of the day. It also doesn't appear a huge number of people are clammoring for collider/telescope time to resolve this mystery. Since I have too much free time, I will attempt to explore this a bit deeper if desired.
 

Thread 'Matter density right after the decoupling'

https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.

Thread 'Hubble Constant, Dark Energy and the Expanding Universe'

Why was the Hubble constant assumed to be decreasing and slowing down (decelerating) the expansion rate of the Universe, while at the same time Dark Energy is presumably accelerating the expansion? And to thicken the plot. recent news from NASA indicates that the Hubble constant is now increasing. Can you clarify this enigma? Also., if the Hubble constant eventually decreases, why is there a lower limit to its value?
