Taking into account a tensor force between nucleons in the nucleus provides a more definite description of the average potential experienced by nucleons and the effective residual interaction between them.

A recent theory of high-energy bottom quark jet quenching in nuclear collisions accentuates the novelty of heavy quark jet dynamics in strongly coupled quark-gluon plasmas discovered at the Relativistic Heavy Ion Collider.
A huge, predicted atomic parity violation has now been observed in ytterbium, further aiding tabletop experimental searches for physics beyond the standard model that complement ongoing efforts at high-energy colliders.
Experiments show that spherical and nonspherical states of a light nucleus near neutron number 28 coexist at the same energy, challenging the usefulness of the notion of stable and persistent “magic numbers.”

The critical point is one of the main features of the phase diagram of strongly interacting quark-gluon matter. Finding this critical point in the lab will require luck and an understanding of the possible experimental signatures.
Heavy nuclei formed by fusion reactions often decay rapidly by fissioning into two fragments. Understanding how these decays occur and over what time scale provides a means to locate the superheavy “island of stability.”
