Read article 'Putting a spin on physics'
Both theoretically and experimentally, spin physics has always been a challenge. Although many physicists proudly point to an increased understanding, some spin puzzles are still waiting for an expl...
Read article 'Quarks in hadrons and nuclei'
The idea of quarks as the ultimate constituents of strongly interacting particles has long been conventional dogma. Less well known, but no less important, is the role of quarks in nuclei. A recent ...

In which direction do quarks point? The HERMES experiment using DESY's HERA electron ring and an ingenious system to control the spin of the electron beam is poised to reveal new insights into the...
Read article '25 years of asymptotic freedom'
A quarter of a century ago, several theorists published an unexpected result which opened the door to quantum chromodynamics (QCD), the unusual field theory that describes quarks and gluons. This ye...
