MiniBooNE is a Cherenkov detector experiment at Fermilab designed to observe neutrino oscillations (BooNE is an acronym for the Booster Neutrino Experiment). A neutrino beam consisting primarily of muon neutrinos is directed at a detector filled with 800 tons of mineral oil (ultrarefined methylene compounds) and lined with 1,280 photomultiplier tubes.{{cite web | url = http://www-boone.fnal.gov/for_physicists/experiment_details/detector.html | title = Detector | access-date = 2015-12-07 | work = MiniBooNE Experiment Details | publisher = Fermilab

MiniBooNE started collecting data in 2002 and was still running in 2017. In May 2018, physicists of the MiniBooNE experiment reported a possible signal indicating the existence of sterile neutrinos.

History and motivation

Experimental observation of solar neutrinos and atmospheric neutrinos provided evidence for neutrino oscillations, implying that neutrinos have masses. Data from the LSND experiment at Los Alamos National Laboratory are controversial since they are not compatible with the oscillation parameters measured by other neutrino experiments in the framework of the Standard Model. Either there must be an extension to the Standard Model, or one of the experimental results must have a different explanation. Moreover, the KARMEN experiment in Karlsruhe |date = 3 August 2011 |url = http://www-ik1.fzk.de/karmen/karmen_e.html |title = KARMEN experiment |archive-url = https://archive.today/20130105232055/http://www-ik1.fzk.de/karmen/karmen_e.html |archive-date = 5 January 2013

Cosmological data can provide an indirect but rather model-dependent bound to the mass of sterile neutrinos, such as the ms | author = S. Dodelson |author2=A. Melchiorri |author3=A.

MiniBooNE was designed to unambiguously verify or refute the LSND controversial result in a controlled environment.

2007

: After the beam was turned on in 2002, the first results came in late March 2007, and showed no evidence for muon neutrino to electron neutrino oscillations in the LSND [low energy] region, refuting a simple 2-neutrino oscillation interpretation of the LSND results. | author = A.
