Surprise difference in neutrino and antineutrino mass lessening with new measurements from a Fermilab experiment
The physics community got a jolt last year when results showed for the first time that neutrinos and their antimatter counterparts, antineutrinos, might be the odd man out in the particle world and have different masses.
LHC experiments eliminate more Higgs hiding spots
Two experimental collaborations at the Large Hadron Collider, located at CERN laboratory near Geneva, Switzerland, announced today that they have significantly narrowed the mass region in which the Higgs boson could be hiding.
Tevatron experiments close in on favored Higgs mass range
Experiments at the Department of Energy’s Fermilab are close to reaching the critical sensitivity that is necessary to look for the existence of a light Higgs particle.
Fermilab experiment discovers a heavy relative of the neutron
Scientists of the CDF collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced the observation of a new particle, the neutral Xi-sub-b (Ξb0).
Fermilab experiment weighs in on neutrino mystery
Scientists of the MINOS experiment at the Department of Energy’s Fermi National Accelerator Laboratory announced today (June 24) the results from a search for a rare phenomenon, the transformation of muon neutrinos into electron neutrinos.
Dark Energy Survey Poised to Probe Cosmic Speed-Up
Scientists announced that the Dark Energy Survey soon expects to make a substantial leap forward in our understanding of why the universe is accelerating and the nature of dark energy.
Fermilab constructs pioneering accelerator test facility
Officials at the Department of Energy’s Fermi National Accelerator Laboratory announced today that the laboratory has started phase II of the construction of a pioneering facility to advance a technology that will be critical to the next generation of particle accelerators.
Fermilab experiments narrow allowed mass range for Higgs boson
New constraints on the elusive Higgs particle are more stringent than ever before.
New measurements from Fermilab’s MINOS experiment suggest a difference in a key property of neutrinos and antineutrinos
Scientists of the MINOS experiment at the Department of Energy’s Fermi National Accelerator laboratory today (June 14) announced the world’s most precise measurement to date of the parameters that govern antineutrino oscillations, the back-and-forth transformations of antineutrinos from one type to another.
Fermilab scientists find evidence for significant matter-antimatter asymmetry
Scientists of the DZero collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced Friday, May 14, that they have found evidence for significant violation of matter-antimatter symmetry in the behavior of particles containing bottom quarks beyond what is expected in the current theory, the Standard Model of particle physics.
