Kljub zelo natančnemu ujemanju z eksperimentom pa ima tako imenovani standardni model nekatere fenomenološke težave (npr. opis nevtrinov, temna snov) in objektivne pomanjkljivosti (kvantizacija naboja, nerazumno ponavljanje interakcij, večje število različnih delcev, itd.). Marsikatero izmed teh težav lahko rešimo, če standardni model nadgradimo v teorijo poenotenja, katera glavna ideja je, da izvirajo vse tri umeritvene interakcije standardnega modela pri visoki energiji iz ene same poenotene interakcije. To istočasno poenoti tudi osnovne gradnike – delce. Posledice te ideje so daljnosežne: avtomatičen obstoj magnetnih monopolov, razpad protona in poenoten opis kvantnih lastnosti snovi. V predavanju bomo nakazali tako teoretske predpostavke kot fenomenološke posledice te zanimive in osnovne ideje.<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt;text-align:justify'>Predavanje bo v slovenščini.<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><b><span style='font-family:"Calibri","sans-serif";color:red'>Lepo vabljeni!</span></b><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></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></div></body></html>
