It’s like stepping into a science fiction film: Eerie blue and green lighting; spherical white chairs with black cushions; touch-operated computer information stations; a full-wall projection of stars and galaxies; and a calming voice from a loudspeaker asking, “Why are we here?”
The idea that a preference in meson decays for matter over antimatter could point to a whole world of unseen particles, including multiple Higgs bosons, just got a blessing.
Like another neutrino result earlier this week, the MiniBooNE experiment has found that antineutrinos, which should follow the same rules as neutrinos, might oscillate in a slightly different way. The results seem to favor a much-debated antineutrino result obtained by the Liquid Scintillator Neutrino Detector experiment in 1990.
A new measurement from the MINOS neutrino experiment today announced an unexpected variance in a property of neutrinos versus antineutrinos. This mass difference parameter, called Δm2 (“delta m squared”), is smaller by approximately 40 percent for neutrinos than for antineutrinos.
During last week's Physics at LHC conference, textbooks were being literally rewritten as experimental particle physicists presented their remeasurements of the data contained in the particle data booklet, which contains all possible data for all existing and hypothetical particles. One theorist presented his prediction for a page from the 2016 version of the booklet.
The Large Hadron Collider's beam brightness has steadily increased over the past two and a half months. It currently takes a minute to see as many collisions as we used to see in a day. Very soon, the same number of collisions will take seconds.
It's been just over two months since the first high-energy proton collisions took place in the Large Hadron Collider, and scientists from the LHC experiments have been working feverishly to analyze the data now pouring from their detectors. The results of the first analyses using real LHC data are being presented this week at the "Physics at LHC" conference at the DESY laboratory in Hamburg, Germany.
The “Spin Path Integrals and Generations” paper got accepted at Foundations of Physics. This initiates a series of emails that make you feel like a real researcher. I’m at the stage where they’ve sent the first cut proofs and asked me to make changes. I screwed up some of the section titles (when I cut [...]
