Measuring the magnetism of antimatter: Researchers measure antiprotons more accurately than ever before
In a breakthrough that could one day yield important clues about the nature of matter itself, a team of Harvard scientists have succeeding in measuring the magnetic charge of single particles of matter and antimatter more ...
Scaling up polymer blobs
Scientists use simulations to test the limits of their object of study—in this case thin films of polymers—to extremes of scale. In a study about to be published in the European Physical Journal E, Nava S ...
Elliptical galaxies much younger than previously thought?
(PhysOrg.com) -- The standard model for elliptical galaxies formation is challenged by a new result uncovered by an international team of astronomers from the Atlas3D collaboration. Team members from CNRS, ...
The debut of the antihydrogen beam
The standard model of particle physics suggests that matter and antimatter are equal and opposite in every way. Yet the observable Universe is made almost entirely of matter—an asymmetry that remains one ...
Best of Last Week – New model for dark matter, Martian clouds and mind to mind conversing
NOvA: Crews complete first block of North America's most advanced neutrino experiment
(Phys.org)—Today, technicians in Minnesota will begin to position the first block of a detector that will be part of the largest, most advanced neutrino experiment in North America.
LHC experiments join forces to zoom in on the Higgs boson
Today during the 50th session of "Rencontres de Moriond" in La Thuile Italy, ATLAS and CMS presented for the first time a combination of their results on the mass of the Higgs boson. The combined mass of ...
Definitely, maybe: Evidence grows for positive ID of Higgs boson
Physicists say they are now almost certain that the curious "Higgs-like particle" revealed last year at CERN is a Higgs boson.
Seeking cracks in the Standard Model
In particle physics, it's our business to understand structure. I work on the Large Hadron Collider (LHC) and this machine lets us see and study the smallest structure of all; unimaginably tiny fundamental partic ...
New measurement of electron–quark scattering
From matching wings on butterflies to the repeating six-point pattern of snowflakes, symmetries echo through nature, even down to the smallest building blocks of matter. Since the discovery of quarks, the ...
QUIET team to deploy new gravity-wave probe in June
A tiny fraction of a second following the big bang, the universe allegedly experienced the most inflationary period it has ever known.
Higgs search: A half-century odyssey
Over half a century, the Higgs boson has evolved from a theory rejected as daft to a cornerstone of our understanding of the Universe.
CMS in 2011: A mountain of particle collision data
Datasets are the currency of physics. As data accumulate, measurement uncertainty ranges shrink, increasing the potential for discoveries and making non-observations more stringent, with more far-reaching ...
Courant's Marateck describes math theory behind Higgs boson finding
Lost in the exhilaration surrounding this summer's presumed discovery of the Higgs boson, the subatomic particle that is a building block of the universe, were the theoretical clues that led to the breakthrough.
