Summary
The MiniBooNE experiment searched for electron neutrino appearance in a muon neutrino beam. No significant excess events were observed, suggesting no neutrino oscillations in this analysis.
Area of Science:
- Particle Physics
- Neutrino Physics
Background:
- Neutrino oscillations are a key phenomenon in particle physics, indicating that neutrinos change flavor as they travel.
- Understanding neutrino oscillations helps in probing fundamental properties of neutrinos and the Standard Model.
Purpose of the Study:
- To search for evidence of electron neutrino (nu e) appearance in a primarily muon neutrino (nu mu) beam.
- To test neutrino oscillation models by analyzing event data.
Main Methods:
- Utilized two largely independent data analyses.
- Focused on reconstructed neutrino energies above 475 MeV.
Main Results:
- Observed no significant excess of events above the expected background.
- The data are consistent with the absence of neutrino oscillations within a two-neutrino appearance-only model.
Conclusions:
- The MiniBooNE experiment found no evidence for nu e appearance under the analyzed conditions.
- The results place constraints on neutrino oscillation parameters within the tested model.

03:37Subatomic Particles
Dalton was only partially correct about the particles that make up matter. All matter is composed of atoms, and atoms are composed of three smaller subatomic particles: protons, neutrons, and electrons. These three particles account for the mass and the charge of an atom.
03:26Electron Configuration of Multielectron Atoms
The alkali metal sodium (atomic number 11) has one more electron than the neon atom. This electron must go into the lowest-energy subshell available, the 3s orbital, giving a 1s22s22p63s1 configuration. The electrons occupying the outermost shell orbital(s) (highest value of n) are called valence electrons, and those occupying the inner shell orbitals are called core electrons. Since the core electron shells correspond to noble gas electron configurations, we can abbreviate electron...
01:14Atomic Nuclei: Nuclear Spin State Population Distribution
Near absolute zero temperatures, in the presence of a magnetic field, the majority of nuclei prefer the lower energy spin-up state to the higher energy spin-down state. As temperatures increase, the energy from thermal collisions distributes the spins more equally between the two states. The Boltzmann distribution equation gives the ratio of the number of spins predicted in the spin −½ (N−) and spin +½ (N+) states.
01:23Magnetic Moment of an Electron
Electrons revolving around a nucleus are analogous to a circular current carrying loop. This current produces a magnetic dipole moment proportional to the electron's orbital angular momentum. Since the orbital angular momentum is quantized in terms of the reduced Planck's constant, the dipole moment is quantized in the Bohr Magneton. The value of the Bohr magneton is 9.27 x 10-24 Am2. Electrons also have an intrinsic spin angular momentum, and the associated spin magnetic moment is...
01:09Electron Behavior
Electrons are negatively charged subatomic particles attracted to and orbit around the positively-charged nucleus of an atom. They reside in spaces associated with energy levels called shells and are further organized into subshells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the nucleus have less energy,...

01:19Thomson's e/m Experiment
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...
