Profiling Extreme Beams: Scientists Devise New Diagnostic for Cutting-Edge and Next-Gen Particle Accelerators

The world’s cutting-edge particle accelerators are pushing the extremes in high-brightness beams and ultrashort pulses to explore matter in new ways. To optimize their performance – and to prepare for next-generation facilities that will push these extremes further – scientists have devised a new tool that can measure how bright these beams are, even for pulses that last only quadrillionths or even quintillionths of a second.

Early Career Spotlight: Zach Marshall Searches for Supersymmetry

Just five years after joining Berkeley Lab as a Physics Division fellow, Zach Marshall is co-leading an international team of researchers in search of supersymmetry — the theory that every known particle has a “superpartner” particle. Now with funding from an early career award announced last November, Marshall and his team are building a powerful super-scheduling platform that will help particle physicists process more data faster without investing in costly new computing infrastructure.

Underground Neutrino Experiment Could Provide Greater Clarity on Matter-Antimatter Imbalance

Scientists working on the MAJORANA DEMONSTRATOR experiment have shown that they can shield a sensitive, scalable germanium detector array from background radioactivity – a critical step to developing a large experiment to study the nature of neutrinos and probe the universe’s matter-antimatter imbalance.

Beyond the WIMP: Unique Crystals Could Expand the Search for Dark Matter

A new particle detector design proposed at the U.S. Department of Energy’s Berkeley Lab could greatly broaden the search for dark matter – which makes up 85 percent of the total mass of the universe yet we don’t know what it’s made of – into an unexplored realm.

From Belgrade to Berkeley: A Postdoctoral Researcher’s Path in Particle Physics

After completing her Ph.D. thesis in calculating the mass of the W boson – a heavier-than-iron elementary particle that mediates one of the universe’s fundamental forces – physics researcher Aleksandra Dimitrievska is now testing components at Berkeley Lab for a scheduled upgrade of the world’s largest particle detectors.

How the Earth Stops High-Energy Neutrinos in Their Tracks

In an analysis of data from an experiment embedded in Antarctic ice, a research collaboration including scientists from Berkeley Lab has demonstrated that the Earth stops high-energy neutrinos – particles that only very rarely interact with matter.

A Flight Path to Physics Success

In a previous career with the U.S. Air Force, Sandra Miarecki flew high above the Earth’s surface. She retired from the Air Force in 2007 to pursue a new calling in physics that would set her sights on particles traveling into the depths of the Earth.

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.

Dark Matter Day Is Approaching … but Don’t Be Afraid of the Dark

A global hunt for the universe’s missing matter is underway, and this autumn everyone is invited to join in. On and around October 31, 2017, events around the world will celebrate the hunt for the universe’s unseen “dark matter.”
