Joint Theory Seminar: Marco Gorghetto

Description <p>Joint Theory Seminar Speaker:&nbsp;Marco Gorghetto<br />mail:&nbsp;mgorghetto@sissa.it<br />Title:&nbsp;Axions from Strings: the Attractive Solution<br />Host: &nbsp;John Terning<br />Room: 432<br />Abstract:&nbsp;</p><p>The axion solution to the strong CP problem also provides a natural&nbsp;dark matter candidate. If the PQ symmetry has ever been restored after&nbsp;inflation, topological defects of the axion field would have formed and&nbsp;produced relic axions, whose abundance is in principle calculable. Using&nbsp;numerical simulations I will present a detailed study of the evolution of&nbsp;axion strings and the resulting spectrum of axion produced. The features found&nbsp;are important for a correct estimate of the total DM abundance.</p>
