Quarks: The Next Frontier in Physics?

Physicists are investigating discrepancies in quark mixing predictions within the Standard Model, which currently do not sum to 100%, suggesting potential new physics. Researchers, including Jordy de Vries, have developed a new framework to more accurately calculate quark mixing, particularly between up and down quarks, using precise measurements from nuclear beta decays. This work aims to refine theoretical models and reduce uncertainties, potentially revealing new physics beyond the Standard Model.

Scientists Unveil Quantum Entanglement Map in Protons

Scientists at Brookhaven National Laboratory have used quantum information science to map quantum entanglement among quarks and gluons inside protons, revealing a complex, dynamic system. This entanglement, occurring at incredibly short distances, affects the distribution of particles resulting from proton-electron collisions. The research, published in Reports on Progress in Physics, provides new insights into proton structure and lays the groundwork for future experiments at the Electron-Ion Collider, which will explore how nuclear environments impact entanglement.

Unveiling the Energy Origins of Mass

While the Higgs field is often credited with giving mass to particles, it actually contributes very little to the mass of the universe. Most of a person's mass comes from the energy of quarks moving at high speeds within protons and neutrons, as described by Einstein's equation E=mc². This energy, rather than the mass of the quarks themselves, accounts for the majority of mass, illustrating that matter is fundamentally made of energy.

Unveiling Neutron's Secret Layers of Matter

Scientists at the Thomas Jefferson National Accelerator Facility have made a breakthrough in understanding the internal structure of neutrons, revealing how quarks and gluons contribute to nucleon spin. This was achieved using a new Central Neutron Detector, developed over a decade, which allowed the first direct detection of neutrons in deeply virtual Compton scattering (DVCS) reactions. The findings, published in Physical Review Letters, advance nuclear physics by providing insights into the spin structure of nucleons and addressing the 'nucleon spin crisis.'

New Predictions for Meson Measurements Unveiled by Scientists

Scientists at Brookhaven National Laboratory have used supercomputers to predict the distribution of electric charges in mesons, particles made of a quark and an antiquark. These predictions, validated through a method called factorization, align with low-energy measurements and will guide future high-energy experiments at the upcoming Electron-Ion Collider (EIC). The research aims to deepen understanding of how quarks and gluons generate the mass and structure of hadrons, which are fundamental to visible matter.

"Honoring a Landmark Physics Breakthrough"

Physicist David Politzer reflects on his groundbreaking 1973 discovery of asymptotic freedom, which revealed how the strong force binds quarks inside atomic nuclei. This discovery, for which he won the 2004 Nobel Prize in Physics, revolutionized particle physics by providing a working framework for quantum chromodynamics (QCD). Politzer discusses his journey, the challenges faced, and the broader implications of his work, which enabled precise calculations and experiments in the field.

"Unleashing the Strongest Magnetic Force in the Universe: A Breakthrough in Nuclear Matter Imprinting"

Scientists at the US Department of Energy's Brookhaven National Laboratory have created the strongest magnetic field ever observed on Earth by inducing off-centre collisions of heavy atomic nuclei in a particle accelerator. This breakthrough allows for the study of the electrical conductivity of quark-gluon plasma, providing new insights into the fundamental building blocks of matter. The magnetic field generated in these collisions is so powerful that it surpasses even that of neutron stars, making it possibly the strongest in the universe. This discovery opens up new avenues for understanding the deep inner workings of atoms and the universe as a whole.

"The Impact of the Strong Force on Gravitational Waves"

Physicists have shown that the behavior of quarks and gluons as the universe cools should leave a distinct signature on the stochastic gravitational wave background, potentially impacting models of the universe post-Big Bang. This finding could help distinguish early universe waves from those originating from other sources, such as astrophysical phenomena. The study suggests that the quantum chromodynamics crossover, which occurred about 10-5 seconds after the Big Bang, could affect the low-frequency gravitational wave signal, providing a way to search for this signature in pulsar timing array data.
