PROSPECT Characterizes the Footprint of Neutrinos

Predictions based on the Standard Model of particle physics don’t always agree with what scientists see in experimental data. One way to examine these differences is emissions of neutrinos from nuclear reactors. As part of this research agenda, scientists in the PROSPECT Collaboration have reported the most precise measurement ever of the energy spectrum of antineutrinos emitted from the fission of uranium-235, providing a new reference energy spectrum and new constraints on the origin of the disagreements between data and models.

Theoretical and Experimental Physics Team Up in the Search for Particle Flavor Change

Scientists recently discovered that neutrinos have mass, counter to long-held understanding. This means that neutrinos can change flavor. Now, advances in theory and experiment are helping scientists to determine whether the neutrinos’ charged counterparts—electrons, muons, and tauons—can also change flavor and how future experiments can look for those changes.

Andrea Delgado unites fundamental, high energy physics with quantum computing

Andrea Delgado, a Eugene P. Wigner Fellow at the Department of Energy’s Oak Ridge National Laboratory, is using quantum computing to help investigate the fundamental building blocks of the universe and to see whether there are particles yet to be found.

Department of Energy Announces $3.6 Million for Research Traineeships to Broaden and Diversify Nuclear Physics

Today, the U.S. Department of Energy (DOE) awarded more than $3.6 million with a focus on broadening and diversifying the nuclear and particle physics research communities through research traineeships for undergraduates from Historically Black Colleges and Universities (HBCUs) and other Minority Serving Institutions (MSIs). The goal of this program is to increase the recruitment and retention of students from groups under-represented in nuclear physics and to create new partnerships with HBCUs and MSIs. Only by accessing the broadest possible pool of potential physicists can the community produce the best possible science.

‘Shining’ Light on the Inner Details and Breakup of Deuterons

Scientists have found a way to “see” inside deuterons, the simplest atomic nuclei, to better understand how particles called gluons are arranged within the deuteron. These collisions can also break the deuteron apart, giving insights into what holds the proton and neutron together. The research helps scientists understand how nuclei emerge from quarks and gluons, and how the masses of nuclei are dynamically generated by gluons.

10 Years Later, Higgs Boson Discoverers Publish Refined Measurements

Particle physics changed forever on July 4, 2012. That was the day the two major physics experiments at CERN’s Large Hadron Collider (LHC), CMS and ATLAS, jointly announced the discovery of a particle that matched the properties of the Higgs boson—a particle theorized decades earlier. The discovery cemented the final piece in the Standard Model of particle physics. Now physicists from the CMS and ATLAS Collaborations detail high-precision results from their latest Higgs boson studies.

Research Breakthrough Means Warp Speed ‘Unruh Effect’ Can Finally Be Tested in Lab Settings

A major hurdle for work at the forefront of fundamental physics is the inability to test cutting-edge theories in a laboratory setting. But a recent discovery opens the door for scientists to see ideas in action that were previously only understood in theory or represented in science fiction.

Brookhaven Chemist Minfang Yeh Wins 2021 DPF Instrumentation Award

UPTON, NY—Minfang Yeh, a senior scientist at the U.S. Department of Energy’s Brookhaven National Laboratory, has won the American Physical Society’s 2021 Division of Particles and Fields (DPF) Instrumentation Award. The award honors Yeh’s pioneering work in the development and production of high-performance water-based liquid scintillators for particle physics experiments, including metal loaded scintillators for rare process experiments.

New results from MicroBooNE provide clues to particle physics mystery

New results from a more-than-decade long physics experiment offer insight into unexplained electron-like events found in previous experiments. Results of the MicroBooNE experiment, while not confirming the existence of a proposed new particle, the sterile neutrino, provide a path forward to explore physics beyond the Standard Model, the theory of the fundamental forces of nature and elementary particles.

Argonne announces 2022 Maria Goeppert Mayer Fellows, honoring the legacy of the physics Nobel Laureate

Argonne’s Maria Goeppert Mayer is one of only four women to win the Nobel Prize in physics. Today, on her 115th birthday, Argonne announces the award of its 2022 Maria Goeppert Mayer Fellowship to four outstanding early-career doctoral scientists.

Basic to Breakthrough: How Exploring the Building Blocks of the Universe Sets the Foundation for Innovation

Particle physics peers into the mysteries of our cosmos while opening the door to future technologies. Research into the Higgs boson, dark energy, and quantum physics reveals insights into the universe and enables innovation in other fields.

Department of Energy Announces $2.85 Million to Support Undergraduate Research Traineeships at HBCUs and other MSIs

Today, the U.S. Department of Energy awarded over $2.85 million with a focus on broadening and diversifying the nuclear and particle physics research communities through research traineeships for undergraduates from Historically Black Colleges and Universities and other Minority Serving Institutions.

Machine Learning System Improves Accelerator Diagnostics

A machine learning system is helping operators resolve routine faults at the Continuous Electron Beam Accelerator Facility (CEBAF). The system monitors the accelerator cavities, where faults can trip off the CEBAF. The system identified which cavities were tripping off about 85% of the time and identified the type of fault about 78% of the time.

Precise Measurement of Pions Confirms Understanding of Fundamental Symmetry

Scientific rules about “chiral symmetry” predict the existence of subatomic particles called pions. The lifetime of a neutrally charged pion is tied to breaking of chiral symmetry. Until recently, measurements of this lifetime have been much less precise than calculations from theory. Physicists have now measured a pion’s lifetime more precisely than ever before.

Signs of “Turbulence” in Collisions that Melt Gold Ions

A new analysis of collisions of gold ions shows signs of a “critical point,” a change in the way one form of matter changes into another. The results hint at changes in the type of transition during the shift from particles to the quark-and-gluon “soup” that filled the early universe. This helps scientists understand how particles interact and what holds them together.

Hunting for Sterile Neutrinos with Quantum Sensors

An international team has performed one of the world’s most sensitive laboratory searches for a hypothetical subatomic particle called the “sterile neutrino.” The novel experiment uses radioactive beryllium-7 atoms created at the TRIUMF facility in Canada. The research team then implants these atoms into sensitive superconductors cooled to near absolute-zero.

Supercomputer Calculations May Give First Look at the Structure of Two-Faced Pions

Pions consist of a quark paired to an antiquark and are the lightest particles to experience the strong force. But until recently scientists did not understand pions’ internal structure because of their short lifespan. Now, an advance in supercomputer calculations using lattice Quantum Chromodynamics may allow scientists to provide an accurate and precise description of pion structure for the first time.
