Celebration of the International Year of Light and Light-based Technologies (IYL 2015) continues in this issue with a look at the challenges in building a new light source in South East Asia, while Viewpoint asks whether the skills developed for high-energy physics could be used to make the dark side of the universe visible. These skills are already being directed at a large-scale project to investigate further what are arguably the most invisible of the elementary particles – the neutrinos. Celebrations also extend to wishing a happy 90th birthday to CERN Courier’s first editor, Roger Anthoine. To sign up to the new issue alert, please visit: http://cerncourier.com/cws/sign-up.

This “double issue” provides plenty to read during what is for many people the holiday season. The feature articles illustrate well the breadth of modern IceCube brings particle physics – from the Standard Model, which is still being tested in the analysis of data from Fermilab’s Tevatron, to the tantalizing hints of news from the deep extraterrestrial neutrinos from the IceCube Observatory at the South Pole. A connection of a different kind between space and particle physics emerges in the interview with the astronaut who started his postgraduate life at CERN, while connections between particle physics and everyday life come into focus in the application of particle detectors to the diagnosis of breast cancer.

  • The Standard Model
    The Standard Model by Christine Sutton In May 1983, the central detector of the UA1 experiment at CERN's proton-antiproton collider showed the tell-tale signature of the long-awaited Z particle as it decays into an electron-positron pair (arrowed). As the electrically neutral carrier of the weak force, the Z° plays a vital role in the Standard Model. The initial evidence from Fermilab (see previous article) for the long awaited sixth ('top') quark puts another rivet in the already firm structure of today's Standard Model of physics. Analysis of the Fermilab CDF data gives a top mass of 174 GeV with an error of ten per cent either way. This falls within the mass band predicted by the sum total of world Standard Model data and underlines our understanding of physics in terms of six quarks and six leptons. Model encompasses all the elemen­ their interactions emerge.

  • The Challenge of Neutrinos by Christine Sutton
    The challenge of neutrinos by Christine Sutton Neutrino pioneers - left to right, Paul Dirac, Wolfgang Pauli., Rudolf Peierls. (Photo MP Niels Bohr Library) Earlier this year, a team of physicists working at Los Alamos claimed a possible sighting of neutrino oscillations (June, page 13). However even before the claim appeared in the scientific literature, newspaper reports had leaked the possible findings and their implications. Detecting particles which can pass unhindered through the Earth provides the ultimate physics challenge. Neutrinos have always captivated public imagination and make compelling reading. In the wake of the latest neutrino episode, Oxford physi­ cist and science writer Christine Sutton looks back on the short but volatile history of the neutrino and its attendant publicity. strangers to controversy, for they beta-decay electrons varies continu­ With the availability of high were in a sense born amidst it, and ously up to a maximum, with peaks energy neutrino beams in the as recent work on neutrino oscilla­ ("lines") at only a few energies.

The Particle Odyssey: A Journey to the Heart of Matter by Frank Close, Michael Marten & FERMILAB Christine Sutton Oxford University Press: 2002. 246 pp. £29.95, $45. Ken Peach The development of the standard model of particles and their interactions is one of the major scientific achievements of the twen- tieth century. The electron was the first ‘elementary particle’ to be discovered, by J. J. Thomson (working largely on his own) in 1897, and the top quark was the last of the standard model’s ‘fundamental fermions’ to be discovered, by two large teams at the Tevatron near Chicago in 1995. In between, special and general relativity, quantum mechanics and a deep understanding of symmetry (explicit and hidden, global and local, absolute and spontaneously broken) have transformed our understanding of the dynamics of the Universe.

This issue takes a look at the discovery and some of what followed at CERN. In CP violation particular, the NA31 and NA48 experiments played a leading role in the discovery of direct CP violation, which helped to understand the phenomenon in the context of the Standard Model of particle physics. Fifty years later, interest in the effect shows no sign of abating, especially after CP violation was also found in B mesons at KEK and SLAC in 2001. Experiments to pin down the phenomenon continue, for example, with B mesons at the LHC, and are also beginning to turn to neutrinos.
