Summary<br />
● <strong>QCD</strong> describes strong <strong>in</strong>teractions<br />
● Non-perturbative <strong>the</strong>ory – non-perturbative effects<br />
– Chiral symmetry break<strong>in</strong>g and conf<strong>in</strong>ement<br />
● Undergoes a <strong>phase</strong> change at high temperatures<br />
– Details are yet unclear<br />
● Can <strong>in</strong> pr<strong>in</strong>ciple have significant impact on <strong>the</strong> evolution of<br />
<strong>the</strong> <strong>early</strong> <strong>universe</strong><br />
– <strong>QCD</strong> parameters lead only to a weak effect<br />
– Strong and cosmological scales have already been to<br />
