Experiments such as Gargamelle (Hasert et al., 1973), Brookhaven’s Alternating (21) This remarkable feature has been exploited extensively in various neutrino experiments, particularly for solar neutrino detection. The Kamiokande neutrino experiment was the first to use this reaction to reconstruct 8 B neutrino events from the Sun and point back to the source. The Super-Kamiokande experiment later expanded the technique, creating a photograph of the Sun using neutrinos (Fukuda et al., 1998).1 The technique was later used by other solar experiments, such as the Sudbury Neutrino Observatory (SNO) (Ahmad et al., 2001, 2002a, 2002b) and Borexino (Alimonti et al., 2002; Arpesella et al., 2008). C. Experimental tests of electroweak theory Neutrino-lepton interactions have played a pivotal role in our understanding of the working of the electroweak force 1 The fact that such a picture was taken underground during both day and night is also quite remarkable. Rev. Mod. Phys., Vol. 84, No. 3, July–September 2012 FIG. 4 (color online). The first candidate leptonic neutral-current event from the Gargamelle CERN experiment. An incoming muonantineutrino knocks an electron forwards (towards the left), creating a characteristic electronic shower with electronpositron pairs. Photograph from CERN. Joseph A. Formaggio and G.

Corrections due to leptonic masses and radiative correlations are ignored. Cross sections are compared to the asymptotic cross section 0 ¼ G2 s=. Listed are also the experiments which F have measured the given reaction, including Gargamelle (Hasert et al., 1973), the Savannah River Plant (Reines, Gurr, and Sobel, 1976), Brookhaven National Laboratory (BNL) (Ahrens et al., 1983; Abe et al., 1989; Ahrens et al., 1990), LAMPF (Allen et al., 1993), LSND (Auerbach et al., 2001), CCFR (Mishra et al., 1990), CHARM (Vilain et al., 1995a; Vilain et al., 1995b), NuTeV (Formaggio et al., 2001), and TEXONO (Deniz and Wong, 2008).
