Just as matter can be converted into energy, so too can energy become matter. That’s what five-dozen Jefferson Lab researchers were counting on for an experiment in Hall A
Albert Einstein figured it out by 1905, as he was formulating his special theory of relativity: while you can’t exactly get something from nothing, you can come close. His famous formula, E=MC2, works both ways. Just as matter can be converted into energy, so too can energy become matter.
That’s just what five dozen researchers were counting on with a Jefferson Lab experiment in Hall A that used the Lab’s electron beam and a liquid hydrogen target to bring to life an unusual particle known as a kaon. The kaon’s unique structure could prove of great help to cosmologists, who should be able to use the results of experiments like the Hall A effort to develop structural models of stellar objects made up of exotic, or "strange" matter, matter that includes kaons as part of their own subatomic architectures. Preliminary findings indicate that kaon production results from the interactions of the particles of light known as photons. The photons create more than just kaons, however. They also produce other particles, known as lambda and sigma, with their own distinctive quark structure. All arise from a constantly churning sea of "virtual" particles that can’t exist until bumped by a jolt of energy such as that provided by the Lab’s accelerator.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
