Napredek je prinesel tudi nova teoretična spoznanja. Med drugim so dokazali, da je mehanizem Kobayashija in Maskawe glavni vzrok opažene kršitve naboja in parnosti. Vseeno ostajata odprti dve uganki. Prvo vprašanje je, zakaj morebitna nova fizika pri energijah reda TeV ne da dovolj jasnih odstopanj od napovedi standardnega modela za procese, pri katerih se spremeni okus kvarkov? Druga uganka pa je razlog za majhnost in hierarhijo parametrov okusa v standardnem modelu. Eksperimenta ATLAS in CMS bosta verjetno ponudila odgovor na prvo vprašanje in nemara celo nekaj namigov glede drugega.<i><o:p></o:p></i></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt;text-align:justify'>Predavanje bo v angleščini.<span style='mso-fareast-language:SL'><o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><strong><span style='font-family:"Calibri","sans-serif";color:red'>Lepo vabljeni!</span></strong><strong><span style='font-weight:normal'><o:p></o:p></span></strong></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal align=center style='text-align:center'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:black'>*****<o:p></o:p></span></p><p class=MsoNormal align=center style='text-align:center'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:black'>We invite you to the 2nd Institute colloquium in the academic year 2013/14.

It led to significant progress in our theoretical understanding. In particular, it was proven that the Kobayashi-Maskawa mechanism is the dominant source of the observed CP violation. Yet, two flavor puzzles remain open: First, if there is new physics at the TeV scale, why does it not generate significant deviations from the standard model predictions for flavor changing processes? Second, why is there smallness and hierarchy in the flavor parameters of the standard model? The ATLAS and CMS experiments are likely to solve the first puzzle, and may even provide clues about the second.<o:p></o:p></p><p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p></div></body></html>
