Abstract

Recent results on low energy e+e- annihilation into hadrons from CMD-2 and 
SND in Novosibirsk, KLOE in Frascati and BaBar at SLAC are described. 
Their implications for the theoretical calculation of the muon anomalous 
magnetic moment are discussed.

First MiniBooNE neutrino oscillation results

Abstract

This seminar reports the initial results from a search for muon neutrino 
to electron neutrino oscillations by the MiniBooNE Collaboration. 
MiniBooNE was motivated by the result from the LSND experiment which 
presented evidence for oscillations at the delta_mass squared scale around 
1 eV2. The MiniBooNE experiment uses a high intensity neutrino beam 
produced by protons from the Fermilab Booster accelerator; the average 
muon neutrino energy for this beam is ~800 MeV. A 1 kton pure mineral oil 
detector instrumented with ~1500 photomultiplier tubes is placed 540 m 
away from the production target and used to identify and measure muon or 
electron neutrino events. MiniBooNE performed a "blind" analysis, where 
all analysis selections and fitting procedures are determined before 
candidate electron neutrino events are examined. Results of this analysis 
will be presented for the current neutrino mode data set corresponding to 
5.58E20 protons on target.
