But a full understanding of the various aspects of the neutrino oscillations is far to be achieved. AIP congratulates Takaaki Kajita and Arthur B. McDonald on their receipt of the Nobel Prize in Physics "for the discovery of neutrino oscillations, which shows that neutrinos have mass." The oscillation process is directly related to the neutrinos' mass: oscillation is only possible if neutrinos have a mass, however small. Such a discovery moment was rewarded with this years Nobel Prize in Physics. This article describes neutrino oscillation experiments; the discovery, the present status and the future prospect.

In cosmology, baryon acoustic oscillations (BAO) are fluctuations in the density of the visible baryonic matter (normal matter) of the universe, caused by acoustic density waves in the primordial plasma of the early universe. OPERA: Additional Supporting Info; OPERA: Comparing the Two Versions; OPERA: Some Arguments Against. Leaders of these two projects would go on to receive the 2015 Nobel Prize in physics for discovering the solution to the solar neutrino problem: neutrino oscillations. In the same way that supernovae provide a "standard candle" for astronomical observations, BAO matter clustering provides a "standard ruler" for Key neutrino discovery helps understand how their oscillation occurs.

Keywords: neutrino, neutrino oscillation, atmospheric neutrino, cosmic ray. Full Record; Other Related Research; Abstract. In the Standard Model neutrinos have always been treated as massless particles and it is only the discovery of neutrino oscillations which has given us any evidence to suggest otherwise. NEUTRINO, DISCOVERY OFThe particle called the neutrino was conceived in 1930 by the Austrian-Swiss theoretical physicist Wolfgang Pauli (19001958) as a possible solution to two vexing problems confronting a widely accepted model of the structure of the atomic nucleus, which used the two elementary constituents of matter then known: the electron and the proton. Indications of such oscillations have been reported before, but the new Discovery of the neutrino oscillations in the atmospheric Super-Kamiokande , solar SNO and reactor KamLAND experiments was a first evidence in favor of a beyond the Cohen-Glashow: OPERA is Self-Contradictory; OPERA vs ICARUS; OPERA: Another Speed Bump; Supernovas and Neutrino At the very beginning, the Universe exponentially expanded during a period known as the cosmic inflation.
