Under construction at Berkeley Lab, the Gamma-Ray Energy Tracking Array, or GRETA, is a cutting-edge instrument for nuclear physics. Software developed at ORNL will enable GRETA to send data to the nation’s fastest supercomputers for immediate analysis, radically reducing data storage needs and enabling real-time experiment adjustments for optimal results.

An early-career physicist mathematically connects timelike and spacelike form factors, opening the door to further insights into the inner workings of the strong force. A new lattice QCD calculation connects two seemingly disparate reactions involving the pion, the lightest particle governed by the strong interaction. One reaction is known as the spacelike process, where an electron is bounced off a pion. The second reaction, known as the timelike process, is when an electron and antielectron collide, annihilate each other, and produce two pions. The lattice QCD numerical calculation is simultaneously able to describe the spacelike and timelike processes, demonstrating the interconnectedness of different reactions described by QCD. While this connection had been observed experimentally, now physicists have the math to corroborate it.

For the first time, researchers have utilized detailed factors such as water depth and temperature to better estimate the capacity for floating solar panels on U.S. reservoirs. Even under conservative projections, these reservoirs present enormous potential, with the ability to support projects generating up to 77,000 megawatts. (Photo: Getty Images)
