Evidence and Search for Sterile Neutrinos at Accelerators

Table 4

The number of data, fitted (constrained) backgrounds, and excess events in the 𝜈_𝑒 and 𝜈_𝑒 analyses for neutrino mode, antineutrino mode, and combined in the neutrino oscillation energy range from 200 to 1250 MeV. The uncertainties include both statistical and constrained systematic errors. All known systematic errors are included in the systematic error estimate.

Mode	Data	Background	Excess
Neutrino mode	952	790.0±28.1±38.7	162.0±47.8
Antineutrino mode	478	399.6±20.0±20.3	78.4±28.5
Combined	1430	1189.7±34.5±52.6	240.3±62.9
