In this talk, I present recent developments on the model building of inflationary classical primordial standard clocks (CPSC) and emphasize their observable consequences. I then present constraints on these models from the latest Planck temperature and polarization data and show how CPSC can address anomalies at different multipoles. Finally, I discuss the prospects for detecting CPSCs with upcoming CMB missions and to distinguish them from other feature models.<\/p>\n<p>\u00a0<\/p>\n<p>Abstract e slide disponibili su: <a class=\"js-copy-to-clipboard moz-txt-link-freetext\" href=\"https:\/\/agenda.infn.it\/e\/braglia\" data-clipboard-text=\"https:\/\/agenda.infn.it\/e\/marinelli\" data-clipboard-action=\"copy\" data-qtip-oldtitle=\"Copy link to clipboard\">https:\/\/agenda.infn.it\/e\/braglia<\/a><\/p>\n<p>\u00a0<\/p>\n<p>Il seminario si terr\u00e0 in modalit\u00e0 remota sulla piattaforma\u00a0 Zoom al seguente indirizzo:<\/p>\n<p><a class=\"moz-txt-link-freetext\" href=\"https:\/\/infn-it.zoom.us\/j\/84261721878?pwd=MDZNaGdBUlcvUUJXa2phSHZVZk5sdz09\">https:\/\/infn-it.zoom.us\/j\/84261721878?pwd=MDZNaGdBUlcvUUJXa2phSHZVZk5sdz09<\/a><br \/><br \/>ID riunione: 842 6172 1878<br \/>Passcode: 611379<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Abstract: Massive fields oscillating around their minima produce specific oscillatory patterns in the density perturbations that record the time dependence of the scale factor in the primordial Universe (hence the name &#8216;Primordial Standard Clocks&#8217;).
