The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe

The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay --- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our Universe, its current state and its eventual fate. The Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed plan for a world-class experiment dedicated to addressing these questions. LBNE is conceived around three central components: (1) a new, high-intensity neutrino source generated from a megawatt-class proton accelerator at Fermi National Accelerator Laboratory, (2) a near neutrino detector just downstream of the source, and (3) a massive liquid argon time-projection chamber deployed as a far detector deep underground at the Sanford Underground Research Facility. This facility, located at the site of the former Homestake Mine in Lead, South Dakota, is approximately 1,300 km from the neutrino source at Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino charge-parity symmetry violation and mass ordering effects. This ambitious yet cost-effective design incorporates scalability and flexibility and can accommodate a variety of upgrades and contributions. With its exceptional combination of experimental configuration, technical capabilities, and potential for transformative discoveries, LBNE promises to be a vital facility for the field of particle physics worldwide, providing physicists from around the globe with opportunities to collaborate in a twenty to thirty year program of exciting science. In this document we provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess.Comment: Major update of previous version.

Indications and warning in Belgium : Brussels is not Delphi

The terrorist attacks in France and Belgium of 2015–2016 that occurred while these countries were in a heightened state of alert raise questions about indications and warning methodology as well as effectiveness of the blanket-protection deployment of security services assisted even by the military. Response and perhaps even more anticipation may require strategic rethinking in light of the predatory attacks that target the most vulnerable spots of the public space. This study looks at threat analysis in Belgium as conducted through her intelligence fusion centre Coordination Unit for Threat Analysis (CUTA)​​​​​​ since its inception in 2006. With a special focus on what is known, at the time of writing, about the terrorist attacks in Paris and Brussels, this study hopes to put into context how the system (mal)functions and will also consider the preventive measures that respond to the threat, and the international aspects which have implications far beyond Belgian borders. Therefore, a case is made for not just a Belgian homeland security framework, but one that fits into an EU-wide security concept

Determination of the D-0 -> K- pi(+) pi(0) and D-0 -> K- pi(+) pi(+) pi(-) coherence factors and average strong-phase differences using quantum-correlated measurements

The first measurements of the coherence factors (R-K pi pi 0 and R-K3 pi) and the average strong-phase differences((delta(K pi pi 0)(D) and delta(K3 pi)(D))) for D-0 -> K- pi(+) pi(0) and D-0 -> K- pi(+) pi(+) pi(-) are presented. These parameters can be used to improve the determination of the unitarity triangle angle gamma in B- -> DK- decays, where D is a D-0 or (D) over bar (0) meson decaying to the same final state. The measurements are made using quantum-correlated, fully reconstructed D-0(D) over bar (0) pairs produced in e(+)e(-) collisions at the psi(3770) resonance. The measured values are: R-K pi pi 0 = 0.84 +/- 0.07, delta(K pi pi 0)(D) = (227(-17)(+14))degrees, R-K3 pi = 0.33(-0.23)(+0.20), and delta(K3 pi)(D) = (114(-23)(+26))degrees. These results indicate significant coherence in the decay D-0 -> K- pi(+) pi(0), whereas lower coherence is observed in the decay D-0 -> K- pi(+) pi(+) pi(-). The analysis also results in a small improvement in the knowledge of other D-meson parameters, in particular, the strong-phase difference for D-0 -> K- pi(+), delta(K pi)(D), and the mixing parameter y
