Particle Physicists Find Proverbial Needle in a Haystack

Particle physicists from the international ZEUS collaboration have found the proverbial needle in a haystack. They identified a mere 15 Z0 bosons in over 500 million collision events at DESY’s former electron–proton accelerator HERA. Z0 particles are carriers of the weak nuclear force, one of four fundamental forces in the universe. Although Z0 bosons have been intensely studied at other particle accelerators, they have never been directly observed in electron–proton collisions before. Z0 production is the rarest process ever measured at HERA.

Top Female Particle Physicist Recognized with Niels Bohr Institute Medal of Honour

The LHC accelerator is running on ‘woman power’, such is a saying at CERN. One of the great top female researchers is the particle physicist Fabiola Gianotti, who for four years has been the head of one of the two large international research groups responsible for detecting the Higgs particle in the ATLAS experiment on 4 July 2012. Fabiola Gianotti has been awarded the Niels Bohr Institute’s Medal of Honour 2013.

Physicists Posit a Theory for Why Scientific Theories Work

Cornell physicists have figured out why science works. Or rather, they’ve posited a theory for why scientific theories work – a meta theory.

Researchers Observe Extremely Rare Decay of Bs Meson Into Two Muons

Researchers from the Paul Scherrer Institute have observed for the first time the extremely rare decay of the Bs meson into two muons. They have determined its decay frequency with sufficient accuracy using data collected by the CMS detector at CERN. Their result agrees with the predictions of the standard model of particle physics.

Quasar Light Method for Measuring Cosmic Distances Wins Lundbeck Foundation Research Prize

Darach Watson has been awarded the Lundbeck Foundation Research Prize for Young Scientists for his outstanding and innovative research in astrophysics, where he has developed a groundbreaking method for measuring distances in the cosmos using the light from distant quasars. The result was selected by Physics World as one of the year’s most important breakthroughs in physics.

TU Vienna Sets New World Record for Terahertz Quantum Cascade Laser

Terahertz waves are invisible, but incredibly useful; they can penetrate many materials which are opaque to visible light and they are perfect for detecting a variety of molecules. Terahertz radiation can be produced using tiny quantum cascade lasers, only a few millimetres wide. This special kind of lasers consists of tailor made semiconductor layers on a nanometer scale.

BSI’s MIIPS Technology Used to Study Quantum Mechanical Effects Behind Photosynthesis

Biophotonic Solutions Inc. (BSI), the world leader in automated laser pulse compression, announces that its "MIIPS" laser pulse characterization and compression technology was used in a two-dimensional (2D) electronic spectroscopy setup for photosynthesis experiments by researchers at the University of Chicago (UChicago).
