High Energy Neutrinos from Space
Thomas K. Gaisser This paper reviews the status of the search for high-energy neutrinos from astrophysical sources. Results from large neutrino telescopes in water (Antares, Baikal) and ice (IceCube) are discussed as well as observations from the surface with Auger and from high altitude with ANITA. Comments on IceTop, the surface component of IceCube are […]
Solar Neutrinos in 2011
January 31, 2012
Alvaro Chavarria I give an overview of the recent developments in the solar neutrino field. I focus on the Borexino detector, which has uncovered the solar neutrino spectrum below 5 MeV, providing new tests and confirmation for solar neutrino oscillations. I report on the updated measurements of the 8B solar neutrino flux by water Cherenkov […]
Neutrino watch
October 19, 2011
… Speed claim baffles CERN theoryfest Even a meeting of elite minds at Europe’s top particle physics lab couldn’t do it: reconciling neutrinos that appear to break the cosmic speed limit with the laws of physics is still beyond us. However, a paper on the speeding neutrinos has been accepted for publication and the first […]
ICARUS Refutes Opera’s Superluminal Neutrinos
October 18, 2011
The saga of the superluminal neutrinos took a dramatic turn today, with the publication of a very simple yet definitive study by ICARUS, another neutrino experiment at the Gran Sasso Laboratories, who has looked at the neutrinos shot from CERN since 2010. The ICARUS team jumped on the chance to test the Opera result based on […]
Faster-Than-Light Neutrino Puzzle Claimed Solved by Special Relativity
October 14, 2011
The relativistic motion of clocks on board GPS satellites exactly accounts for the superluminal effect, says physicist It’s now been three weeks since the extraordinary news that neutrinos travelling between France and Italy had been clocked moving faster than light. The experiment, known as OPERA, found that the particles produced at CERN near Geneva arrived […]
The neutrino song
October 12, 2011
“Toor a loo, toor a loo, toor a loo, toor-a-lino, is light now slower than a neutrino?” is the question of Corrigan Brothers…. http://youtu.be/vpMY84T8WY0
Measurement of the neutrino velocity with the OPERA detector in the CNGS beam
September 23, 2011
The OPERA neutrino experiment at the underground Gran Sasso Laboratory has measured the velocity of neutrinos from the CERN CNGS beam over a baseline of about 730 km with much higher accuracy than previous studies conducted with accelerator neutrinos. The measurement is based on high-statistics data taken by OPERA in the years 2009, 2010 and […]
The Daya Bay reactor neutrino experiment begins taking data
August 16, 2011
The Daya Bay Reactor Neutrino Experiment has begun its quest to answer some of the most puzzling questions about the elusive elementary particles known as neutrinos. The experiment’s first completed set of twin detectors is now recording interactions of antineutrinos (antipartners of neutrinos) as they travel away from the powerful reactors of the China Guangdong […]
A new neutrino oscillation
July 19, 2011
Starting in the late 1960s, neutrino detectors began to see signs that neutrinos, now known to come in the flavors electron (νe), muon (νμ), and tau (ντ), could transform from one flavor to another. The findings implied that neutrinos must have mass, since massless particles travel at the speed of light and their clocks, so […]
The antineutrino vanishes differently
July 6, 2011
CPT symmetry, the combination of charge conjugation, parity inversion, and time reversal, is a fundamental symmetry of particle and nuclear physics and is considered sacred. It is conserved in field theories that explain the strong, weak, and electromagnetic interactions. In the lepton sector, CPT symmetry requires that muon neutrino disappearance oscillations be identical to muon […]
