Read article 'Don’t be afraid of the dark'
Unveiling the nature of dark matter matter revealing itself only via its gravitational interaction is a continuous challenge in contemporary cosmology. The job of particle physics experiments i...
Read article 'Superstrings, black holes and gauge theories'
Finding a quantum field theory that includes gravity has eluded the best minds of physics. Yaron Oz of CERN explains how the theory of superstrings modifies classical geometry, and how the secrets of...
Read article 'Linear collider physics: the next challenge'
While CERN's LHC proton collider is the world's major particle physics project, other avenues of research could yield complementary studies. Here, David Miller looks at the possibilities for a linea...
Read article 'KamLAND: neutrinos from heaven and Earth'
The Japanese Kamiokande underground detector played a leading role in the study of neutrinos produced via cosmic rays and also helped to pioneer the subject of neutrino astronomy. With Kamiokande now ...
Read article 'Raising the dead detectors'
The RD39 collaboration at CERN investigates heavily irradiated silicon detectors operated at cryogenic temperatures. Its results show that, below 100 K, such detectors can be brought back to life. T...
Read article 'Perfect rose'
The Rose collaboration (RD48: R&D on silicon for future experiments) at CERN has tackled the same problem as RD39,
from a different angle but with similar success. Its approach is "defect engineering...
Read article 'Probing the pomeron'
What ultimately controls the way particles interact? Different particles appear to interact at high energies in similar ways through a mechanism known as pomeron exchange. Sandy Donnachie explains wha...

Read article 'The quest for gravitational waves'
The gravitational waves emitted by accelerated masses were predicted by Albert Einstein's General Theory of Relativity as long ago as 1916, but so far remain undetected.
Read article 'Making tracks for the LHC'
Pictures ultimately provide the most graphic record of of particle interactions. For CERN's LHC collider, sophisticated electronic "eyes" at the heart of the big ATLAS and CMS detectors will pick up ...
