The weak interaction and fusion?

Click For Summary
SUMMARY

The weak interaction is a fundamental force that governs the fusion of hydrogen in stars, particularly through the proton-proton chain reaction. This process begins with the formation of deuteron, which is facilitated by weak interactions and is characterized by a significant energy barrier, making it the slowest step in the chain. The proton-proton chain is the dominant mechanism for hydrogen fusion in the sun, highlighting the critical role of weak interactions in stellar processes.

PREREQUISITES
  • Understanding of weak interactions in particle physics

I've heard that the weak interaction actually governs fusion between hydrogen especially in the sun, how does this actually works?

The proton-proton chain is by far the predominant mechanism. The first step - the formation of deuteron - is governed by weak interactions, and is also the slowest due to the high energy barrier involved.
