Analysis
This paper highlights the application of the Trojan Horse Method (THM) to refine nuclear reaction rates used in Big Bang Nucleosynthesis (BBN) calculations. The study's significance lies in its potential to address discrepancies between theoretical predictions and observed primordial abundances, particularly for Lithium-7 and deuterium. The use of THM-derived rates offers a new perspective on these long-standing issues in BBN.
Key Takeaways
- •The Trojan Horse Method (THM) is used to measure nuclear reaction cross sections at astrophysical energies.
- •THM-derived reaction rates are incorporated into Big Bang Nucleosynthesis (SBBN) calculations.
- •Using THM rates leads to significant differences in predicted primordial abundances.
- •The use of THM rates improves agreement with observations, particularly for $^7$Li and deuterium.
Reference
“The result shows significant differences with the use of THM rates, which in some cases goes in the direction of improving the agreement with the observations with respect to the use of only reaction rates from direct data, especially for the $^7$Li and deuterium abundances.”
