The D0 collaboration at Fermilab has applied a new technique for measuring the mass of the top quark that yields a more precise result than previously.
A new variation on an old technique is yielding the most precise results so far in lattice calculations of quantum chromodynamics, the theory of strong interactions, as Christine Davies explains.
The H1 experiment studying electron-proton collisions at DESY's HERA accelerator may have discovered a new five-quark particle.
While quantum chromodynamics (QCD) is considered to be the theory of strong interactions, it is very difficult to use it to make predictions of processes over distances of the order of the size of had...
The superlarge nuclei studied at CERN's ISOLDE facility can now vie for attention with the superdeformed and the superheavy, as David Lunney explains.
The first results from the FINUDA experiment at INFN's Frascati National Laboratory show that the detector is performing well and is in good shape for its future studies of hypernuclear physics.
A team from the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, and the Lawrence Livermore National Laboratory (LLNL) in the US, has published results on the synthesis of two new superhe...
The Quark Matter 2004 conference, held in Oakland, California, in January, provided participants with evidence for the elusive quark-gluon plasma. Spencer Klein and Joakim Nystrand describe the highli...
Volker Burkert reports on Pentaquark 2003, the first topical workshop on exotic baryons, which was held at Jefferson Lab in November.
Researchers using the Penning trap mass spectrometer, ISOLTRAP, at the ISOLDE facility at CERN have published new high-precision measurements of the mass of short-lived radionuclides of argon and copp...
