AbstractAbstract
[en] In this paper, we describe the performance of the readout system for MONOLITH developed at the LNGS. This system is based on the use of flat cables as readout elements, instead of the conventional copper strips. The advantages of flat cable strips are the good performance, the easy installation and the possibility to realize complex readout systems. The X-coordinate readout system (X-system) is composed by 15 m long, Flat Cable Strips (FCS). The distribution of the time difference between the streamer signals transmitted at both the ends of the X-system FCS has a sigma resolution of the order of 100 ps. This resolution allows the measurement of the particle direction by means of the time-of-flight technique and can be exploited to measure the Y-coordinate with a resolution in the order of 1 cm. The Y-coordinate system is composed by short FCS connected together by a flat cable acting as a bus line. It allows the installation of the electronics outside the apparatus minimizing the number of channels

AbstractAbstract
[en] The Compressed Baryonic Matter experiment (CBM) will be based at the new Facility for Antiproton and Ion Research (FAIR), which will deliver heavy-ion beams up to energies of 14 A GeV. In nucleus-nucleus collisions at these beam energies strongly interacting matter with densities up to 10 times normal nuclear matter is expected to be produced. The key objective of CBM is to investigate the QCD phase diagram in the region of high baryon-densities, where a first order phase transition from hadronic to partonic matter as well as a chiral phase transition is expected to occur, representing a substantial discovery potential at FAIR energies. As a fixed-target experiment CBM is consequently designed to cope with very high interaction rates up to 10 MHz. This will allow to perform high precision measurements of extremely rare probes which have not been accessible by previous nucleus-nucleus experiments in this energy regime. To achieve the high rate capability CBM will be equipped with fast and radiation hard detectors employ- ing free-streaming readout electronics. A prototype high-speed Data Aquisition (DAQ) system was built in 2016. It has been successfully deployed at a CBM beamtest at the SPS accelerator at CERN, where it has forwarded data from the detector front-ends of the TOF and MUCH subsystems to a prototype of the First Level Event Selector (FLES). We report on the status of this CBM DAQ prototype.

AbstractAbstract
[en] We propose a general description for the unambiguous discrimination of mixed states according to the system-environment coupling, and present a procedure to reduce this to a standard semidefinite programming problem. In the two-state case, we introduce the canonical vectors and partly simplify the problem to the case of discrimination between pairs of canonical vectors. By considering the positivity of the 2x2 matrices, we obtain a series of new upper bounds for the total success probability, which depends on both the prior probabilities and specific state structures

AbstractAbstract
[en] This contributions summarizes the discussions that have taken place in the Hall B community on the possibilities to upgrade the CLAS detector to higher energy operation. After reviewing the present capabilities of CLAS and the associated Hall B instrumentation, the limitations of the equipment are pointed out, especially in the context of the physics program at higher energy. Possibilities are discussed to overcome these limitations by modest changes to the present equipment

AbstractAbstract
[en] A detector layout using O(cm) long, radially pointing, scintillating fibers at large radius is investigated. Such a geometry allows discrimination between high and low pT particles based on their angle of incidence and because high pT particles deposit large ionization in one fiber, while low pT particles deposit small ionization in many fibers. A pixelated array of these fibers provides a phi-z projection of particle trajectories, from which the track parameters can be calculated. The simulated track parameter resolutions are presented, and some of the unique detector and electronics issues associated with such a design are discussed.

AbstractAbstract
[en] Quantum state separation is a more general operation for identifying states than unambiguous discrimination. In this paper, we derive an upper bound on the success probability of separation among n states with arbitrary a priori probabilities, extending some of the important results given in the literature. This conclusion generalizes that obtained by Chefles and Barnett for separating two states having equal a priori probabilities. Some of the known bounds on the success probabilities of unambiguous discrimination such as the Ivanovic-Dieks-Peres limit, the more general limit by Jaeger and Shimony, and an upper bound for the case of unambiguously discriminating n states, are special cases of our results. Notably, we also give implicitly a different method to derive the upper bound on the probability of successful unambiguous discrimination among n states. Finally, we apply our conclusion to quantum cloning and then derive some upper bounds on the success probabilities for several probabilistic cloning machines. (author)

AbstractAbstract
[en] To extract the invaluable information on the nature of dark energy hidden in the history of the Hubble factor we must have at our disposal simple and practical criteria to be used on the data. Here, we propose some diagnostics based on H(z) that may help discern whether the dark energy interacts with dark matter or not and whether it is phantom or quintessence in nature.
