The BASE team’s solution was to develop a device that can transport trapped antiprotons on a truck for substantial distances. It is this device, known as BASE-STEP (for Symmetry Tests in Experiments ...

Scientists have successfully relocated protons outside of an antimatter laboratory with the help of an autonomous, open Penning trap. This breakthrough marks a significant step toward transporting ...

Protons are the basic building blocks of matter. Together with neutrons, they form atomic nuclei. These minute, positively ...

As they studied atomic disintegration, they kept seeing that the atomic number (number of protons in the nucleus, equivalent to the positive charge of the atom) was less than the atomic mass ...

Since a nucleus contains protons and neutrons, most of the mass of an atom is concentrated in its nucleus.

Top quarks, in particular, are already the heaviest known elementary particles—the basic particles that makes up matter—clocking in at 184 times the mass of a proton. Some quarks produced from smashed ...

The proton had been proposed as being the nuclear particle responsible for the positive charge of the nucleus and for some of the nuclear mass. However, there was still a difference between the ...

Together with results by some nuclear mass models (denoted by pink block), calculations suggest that the isospin asymmetry of heavy nuclei at the neutron drip line tends toward a saturation value.

The BASE international research collaboration, in which Heinrich Heine University Düsseldorf (HHU) is strongly involved, has successfully relocated ...
