A dense quark liquid is distinct from a dense nucleon liquid

Atomic nuclei are made of nucleons (like protons and neutrons), which themselves are made of quarks. When crushed at high densities, nuclei dissolve into a liquid of nucleons and, at even higher densities, the nucleons themselves ...

Further evidence for quark-matter cores in massive neutron stars

Neutron-star cores contain matter at the highest densities reached in our present-day universe, with as much as two solar masses of matter compressed inside a sphere of 25 km in diameter. These astrophysical objects can indeed ...

Not all jets radiate equally in quark-gluon plasma, study finds

Studying nuclear matter under extreme conditions allows scientists to better understand how the universe might have looked right after its creation. Scientists at the Large Hadron Collider achieve the conditions for recreating ...

How nanoplastics can influence metabolism

PET—the plastic used to make bottles, for example—is ubiquitous in our natural environment. In a joint study, scientists from Leipzig University and the Helmholtz Centre for Environmental Research (UFZ) investigated the ...

Using quantum technology to constrain new particles

Yet-to-be discovered axions and axion-like particles may be the key to explaining some of the deepest puzzles of our universe, such as dark matter and charge-parity violation in strong interactions. Several recent theories ...

New insights into neutron star matter

An international research team has for the first time combined data from heavy-ion experiments, gravitational wave measurements and other astronomical observations using advanced theoretical modeling to more precisely constrain ...
