Measurement of Exclusive rho+rho- Production in Mid-Virtuality Two-Photon Interactions and Study of the gamma gamma* -> rho rho Process at LEP [PDF]

open access: yes, 2005
Exclusive rho+rho- production in two-photon collisions between a quasi-real photon, gamma, and a mid-virtuality photon, gamma*, is studied with data collected at LEP at centre-of-mass energies root(s)=183-209GeV with a total integrated luminosity of 684 ...

Play and virtuality

open access: yesEtikk i Praksis: Nordic Journal of Applied Ethics, 2010
The similarities between virtuality and play are obvious, beginning with, for instance, the ubiquitous character of both. This paper deals with how insights from research on play can be used to enlighten our understanding of the ethical dimensions of ...

Chiral Disorder in QCD [PDF]

open access: yes, 1998
Using the Gell-Mann-Oakes-Renner (GOR) relation and semi-classical arguments, we show that the bulk quark spectrum in QCD exhibits a variety of regimes including the ergodic one described by random matrix theory. We analyze the quark spectral form-factor

Virtual colonoscopy

open access: yesBritish Journal of Surgery, 2002
Computerized tomographic colonography (CT colonography) is a new, non-invasive technique that has been developed over the last few years; it looks at the large bowel in detail. In this chapter we look at how the examination is performed and we consider how the images are displayed.
