The ATLAS Experiment at the CERN Large Hadron Collider

Abstract: The ATLAS detector as installed in its experimental cavern at point 1 at CERN is described in this paper. A brief overview of the expected performance of the detector when the Large Hadron Collider begins operation is also presented.

The Psychology of Criminal Conduct

Abstract: Throughout the last decades the so-called Psychology of criminal conduct, which agglutinates scientific knowledge surrounding criminal phenomena, has been taking shape. We can find among the principal fields of interests an explanation for antisocial behaviour where learning theories, analyses of individual characteristics, strain-agression hypotheses, studies on social vinculation and crime, and the analyses of criminal careers are relevant. This last sector, also denominated ‘developmental criminology’, investigates the relationship between the beginning and maintenance of criminal activity and diverse risk predictors (singular and social, static and dynamic). Their results have had great relevance in the creation of crime prevention and treatment programs. Psychological treatments of offenders are aimed at the modification of those risk factors, known as ‘criminogenic needs’, which are considered to be directly related to their criminal activity. In particular, treatment programs attempt to provide criminals (whether juveniles, abusers, sexual aggressors, etc.) with new repertoires of prosocial behaviour, develop their thinking, regulate their choleric emotions, and prevent relapses or recidivisms in crime. Lastly, nowadays the Psychology of criminal conduct places special emphasis on the prediction and management of the risk for violent and antisocial behaviour, a field which will be addressed in a subsequent paper of this same monograph.

Review of Particle Physics

Abstract: This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as the Standard Model, particle detectors, probability, and statistics. Among the 108 reviews are many that are new or heavily revised including those on neutrino mass, mixing, and oscillations, QCD, top quark, CKM quark-mixing matrix, V-ud & V-us, V-cb & V-ub, fragmentation functions, particle detectors for accelerator and non-accelerator physics, magnetic monopoles, cosmological parameters, and big bang cosmology.

Direct evidence for neutrino flavor transformation from neutral current interactions in the Sudbury Neutrino Observatory

Abstract: Observations of neutral-current nu interactions on deuterium in the Sudbury Neutrino Observatory are reported. Using the neutral current (NC), elastic scattering, and charged current reactions and assuming the standard 8B shape, the nu(e) component of the 8B solar flux is phis(e) = 1.76(+0.05)(-0.05)(stat)(+0.09)(-0.09)(syst) x 10(6) cm(-2) s(-1) for a kinetic energy threshold of 5 MeV. The non-nu(e) component is phi(mu)(tau) = 3.41(+0.45)(-0.45)(stat)(+0.48)(-0.45)(syst) x 10(6) cm(-2) s(-1), 5.3sigma greater than zero, providing strong evidence for solar nu(e) flavor transformation. The total flux measured with the NC reaction is phi(NC) = 5.09(+0.44)(-0.43)(stat)(+0.46)(-0.43)(syst) x 10(6) cm(-2) s(-1), consistent with solar models.
