As new technology makes it possible to perform experiments that were unimaginable a decade ago, Eve Marder argues that we can still learn from the past.

J/q/SUPPRESSION BY QUARK-GLUON PLASMA FORMATION ~

If high energy heavy ion collisions lead to the formation of a hot quark-gluon plasma, then colour screening prevents ce binding in the deconfined interior of the interaction region. To study this effect, the temperature dependence of the screening radius, as obtained from lattice QCD, is compared with the J/~' radius calculated in charmonium models. The feasibility to detect this effect clearl...

THE IOTA IN RADIATIVE J/q!. DECAYS bY

The continued study of light meson spectroscopy holds out two inviting prospects: (A) We can discover more about the mesons with masses 1 + 2 GeV/c2, (B) if anomalous mesons are identified we will have found either exotics (states with quantum numbers not permitted by the standard quark model), hybrids (states which are quark-gluon mixtures) or glueballs (bound gluon states). Both these objecti...

CHARMONIUM SPECTROSCOPY FROM INCLUSIVE PHOTONS IN J / Q AND q

The Crystal Ball detector at SPEAR is used to study the inclusive photon spectra in decays of the J/$ and +', with double our previous data sample. Branching fractions for +' + y~~,~,~ have been measured as (9.7?0.6)%, (8.8 &0.5)% and (7.7 ?0.5)% respectively. Combining measurements from inclusive and exclusive Crystal Ball studies our best values for the natural widths are, r ( tot x0,1,21 = (...

The Grandmother Effect

Two classes of explanation have been advanced to explain women’s long post-menopausal life span – that it is an epiphenomenon of increased longevity or an evolved adaptation. While there is no decisive evidence to choose between them, the latter appears more likely. Two mechanisms for the evolved adaptation have been proposed, the ‘mother effect’ and the ‘grandmother effect’. It is argued that ...
