New Study: Scientists Narrow Down the Search for Dark Photons Using Decade-Old Particle Collider Data

A fresh analysis of particle-collider data, co-led by Berkeley Lab physicists, limits some of the hiding places for one type of theorized particle – the dark photon, also known as the heavy photon – that was proposed to help explain the mystery of dark matter.

Experiment Provides Deeper Look into the Nature of Neutrinos

The first glimpse of data from the full array of a deeply chilled particle detector operating beneath a mountain in Italy sets the most precise limits yet on where scientists might find a theorized process to help explain why there is more matter than antimatter in the universe.

Scientists Decode the Origin of Universe’s Heavy Elements in the Light from a Neutron Star Merger

On Aug. 17, scientists around the globe were treated to near-simultaneous observations by separate instruments that would ultimately be confirmed as the first measurement of the merger of two neutron stars and its explosive aftermath.

New Simulations Could Help in Hunt for Massive Mergers of Neutron Stars, Black Holes

Scientists at Berkeley Lab have developed new computer models to explore what happens when a black hole joins with a neutron star – the superdense remnant of an exploded star.

Report: Compact, Precise Beam Could Aid in Nuclear Security

A Berkeley Lab-led report highlights a new, compact technique for producing beams with precisely controlled energy and direction that could “see” through thick steel and concrete to more easily detect and identify concealed or smuggled nuclear materials for national security and other applications.

Heavy Particles Get Caught Up in the Flow

New, high-precision measurements of the subatomic mix of particles produced by smashing gold nuclei together benefit from a Berkeley Lab-developed device known as the “Heavy Flavor Tracker.”

FIONA to Take on the Periodic Table’s Heavyweights

A new tool at Berkeley Lab will be taking on some of the periodic table’s latest heavyweight champions to see how their masses measure up to predictions.

Filling in the Nuclear Data Gaps

Berkeley Lab’s Nuclear Data Group is conducting new experiments to address common data needs in nuclear medicine, nuclear energy and fusion R&D, security, and counterproliferation work.

Berkeley Lab Awarded $4.6 Million for Transformational Agriculture Technologies

ARPA-E has awarded Berkeley Lab $4.6 million for two projects to “see” into the soil and ultimately develop crops that take carbon out of the atmosphere. One technology aims to use electrical current to image the root system. The other will use neutron scattering to measure the distribution of carbon and other elements in the soil.

Simulations Show Swirling Rings, Whirlpool-Like Structure in Subatomic ‘Soup’

Powerful supercomputer simulations of high-energy collisions between atomic cores provide new insights about the complex structure of a superhot fluid called the quark-gluon plasma.
