Electron beamlets as observed on YAG screens at varying distances from a cathode source. Credit: Argonne National Laboratory Beam-driven wakefield acceleration approaches are promising candidates for future large-scale machines, including X-ray free electron lasers and linear colliders, as they have the potential to improve efficiency and reduce operation cost. One […]

An artistic rendering of the XMM-Newton (X-ray multi-mirror mission) space telescope. A study of archival data from the XMM-Newton and the Chandra X-ray space telescopes found evidence of high levels of X-ray emission from the nearby Magnificent Seven neutron stars, which may arise from the hypothetical particles known as axions. […]

At the University of Notre Dame, part of the Oak Ridge Deuterated Spectroscopic Array measured a reaction that causes noise in some neutrino detectors. Credit: Michael Febbraro/ORNL, U.S. Dept. of Energy Led by the Department of Energy’s Oak Ridge National Laboratory, a new study clears up a discrepancy regarding the […]

ANIMATION Scientific articles in the field of physics are mostly very short and deal with a very restricted topic. A remarkable exception to this is an article published recently by physicists from the Universities of Münster and Düsseldorf. The article is 127 pages long, cites a total of 1075 sources […]

Starting from individual ultracold atoms, Heidelberg University […]

In the 1970s, physicists uncovered a problem with the Standard Model of particle physics—the theory that describes three of the four fundamental forces of nature (electromagnetic, weak, and strong interactions; the fourth is gravity). They found that, while the theory predicts that a symmetry between particles and forces in our Universe […]

The Compact Muon Solenoid (CMS) is a general-purpose detector at the Large Hadron Collider (LHC). Credit: CERN The bounds are some of the tightest yet on the existence of third-generation leptoquarks. At the most fundamental level, matter is made up of two types of particles: leptons, such as the electron, […]

The Borexino research team has also succeeded in detecting neutrinos from the sun’s second fusion process, the Carbon Nitrogen Oxygen cycle (CNO cycle) for the first time.
