Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain ...

In this video, we explore the existence of neutrons and their transformation into protons. We discuss why free neutrons are unstable and the significance of mass in particle stability. Key topics ...

Newly discovered particles have incited a fierce debate among experts about the correct picture of matter at the quantum scale. In August 2003, an experiment at the KEKB particle accelerator in Japan ...

Physicists see top quarks and Higgs bosons emanating from the same collisions in new results from the Large Hadron Collider. Today two experiments at the Large Hadron Collider at CERN announced a ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. However, there are inherent limits to the accuracy of ...

Billions of times each minute, the Large Hadron Collider (LHC) smashes protons together, unleashing a maelstrom of energy that crystallizes into more protons, neutrons, and less familiar cousins of ...

Eric Mack has been a CNET contributor since 2011. Eric and his family live 100% energy and water independent on his off-grid compound in the New Mexico desert. Eric uses his passion for writing about ...

Quarks are commonly considered by physicists as the very building blocks of reality. But even quarks’ greatest champions admit they are extremely bizarre entities. Quarks are believed to have ...

Heavy quarks (Q) interact most strongly with quark-gluon plasma (QGP)—exhibiting a short mean free path (zig zags)—near the transition temperature (near T/Tc = 1, in lower left), and less strongly ...
