Plan za sledecih ~60 minuta · Nesto licno · OPERA Eksperiment - Zasto je sve to toliko komplikovano? ! · Buducnost Fizike Elementarnih Cestica, Fermilab, buducnost? · Sledecih 5 godina? · Sledecih 10 godina? ? ? M. Popovic 2

Tipican Neutrino Eksperiment Mini. Boon Dacay Channal Akcelerator, Meta, Kolektor, Kanal Raspada, Slobodni put, Detector OPERA (Oscillation Project with Emulsion-t. Racking Apparatus) je eksperiment za proucavanje mu – tau neutrino oscilacija Merenje brzine je dobijeno uporedjivanjem distribucije protonskog snopa koji je izbacen iz akceleratora i distribucije neutrina koji su registrovani u detektoru M. Popovic 4

Sta je bilo, Sta ce biti, Sta ti niko ne moze oduzeti • Super Nova 1987, detektor je registrovao 3 sata razliku izmedju pojave neutrina ( mislim 4 neutrina) i fotonskog talasa • MINOS - Neutrino eksperiment je nasao( pre oko GODINU DANA) takodje slican efekat ( ali sa sigurnoscu samo od 1. 8 sigma) • OPERA - rezultat je objavljen sa sigurnoscu od 6 sigma • OPERA - rezultat brzine svetlosti je 10000 puta brzi od SN 1987 A • • MINOS (Fermilab) gradi instrumentaciju koja ce 10 puta biti preciznija od postojece. Novi set podataka se ocekuje krajem 2012 JPARC(Japan) ce najverovatnije probati da ponovi eksperiment Teoreticari ce napraviti ~1000 novih teorija M. Popovic 5

g-2 Eksperiment The muon spin and momentum vectors rotate at slightly different frequencies if the gyromagnetic ratio differs from two, resulting in the famous muon g-2 'wiggle' plot. The current comparison to the accepted theory shows a deviation of more than 3 standard deviations, which might be an indication of New Physics beyond the Standard Model. M. Popovic 7

Mu 2 e Eksperiment, mu ->electron bez neutrina Researchers have observed quarks converting from one type, or flavor, to another. They have also observed neutrinos oscillating from one flavor to another. This leads them to wonder if members of the charged lepton family, the electron, muon and tau particles, have a similar ability to convert to one another. Such a process, called charged lepton flavor violation, would represent unambiguous evidence of new physics. M. Popovic 8
