Overview – <strong>QCD</strong> – F<strong>in</strong>ite Temperature <strong>QCD</strong> – Unsettled Issues – Early Universe: Nucleosyn<strong>the</strong>sis - Summary<br />
Impact on Nucleosyn<strong>the</strong>sis I<br />
● Baryon-to-photon ratio is <strong>in</strong>fluenced by <strong>QCD</strong><br />
<strong>phase</strong> <strong>transition</strong><br />
– Quarks electrically charged<br />
● Baryon distribution can also be <strong>in</strong>fluenced<br />
– Baryon density <strong>in</strong> <strong>the</strong> high-temperature <strong>phase</strong><br />
higher<br />
– Light quarks vs. heavy baryons<br />
● 1 st order <strong>phase</strong> <strong>transition</strong> leads to bubble<br />
formation<br />
