super-kamiokandeLSU Physicists Collaborate on T2K CP Violation Results to Explain Workings of Universe:  LSU physicists Thomas Kutter and Martin Tzanov were among the international T2K Collaboration who recently announced their findings on the symmetry between neutrino and antineutrino oscillation. With newly collected antineutrino data, T2K has performed a new analysis, fitting both neutrino and antineutrino modes simultaneously. T2K’s new data continue the trends observed in 2015, which is a preference for maximal disappearance of muon neutrinos, as well as a discrepancy between the electron neutrino and electron antineutrino appearance rates.

On December 26, 2015 at 03:38:53 UTC, scientists observed gravitational waves-ripples in the fabric of spacetime-for the second time. The gravitational waves were detected by both of the twin Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA. Read more

Extreme light from frozen argon LSU physicists Mette Gaarde, Mengxi Wu, Kenneth Schafer, and Dana Browne, in collaboration with a team of researchers at SLAC/Stanford University have directly compared the ultrafast, extreme ultraviolet radiation emitted by argon atoms when they are in their gas phase or in their weakly bound solid phase and found significant differences between them, as reported today in the journal Nature. The results yield new clues about how energetic electrons in a solid behave, and may yield new compact sources of short wavelength radiation. Read more
