(Phys.org)—A team of researchers with the University of Adelaide and the Australian National University has found that the excited state of the Lambda baryon, Λ(1405), is actually a type of quark molecule. In their paper ...
The fact that the neutron is slightly more massive than the proton is the reason why atomic nuclei have exactly those properties that make our world and ultimately our existence possible. Eighty years after the discovery ...

It is often claimed that the Ancient Greeks were the first to identify objects that have no size, yet are able to build up the world around us through their interactions. And as we are able to observe the world in tinier ...

Shortly following the Big Bang, the Universe was filled with a chaotic primordial soup of quarks and gluons, particles which are now trapped inside of protons and neutrons. Study of this quark-gluon plasma requires the use ...

Over the past few days, the SPS has been accelerating argon ions, which have started to be sent to the NA61/SHINE experiment. This operating mode, using a new type of ion, required a number of modifications to the accelerator.

When particles collide inside Brookhaven Lab's Relativistic Heavy Ion Collider (RHIC), they melt at trillion-degree temperatures and form a friction-free "perfect" liquid. This quark-gluon plasma, composed of the liberated ...
