Fizika okusa: včeraj, danes, jutri

 

V preteklih letih je eksperimentalna fizika okusa ter kršitve naboja in
parnosti zelo napredovala. 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.

Predavanje bo v angleščini.

Lepo vabljeni!

Flavor physics: past, present, future

 

In recent years, huge progress in experimental flavor physics and CP
violation was achieved. 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.
