In the K1.8 beam-line at Hadron Experimental Facility of J-PARC, a new magnetic spectrometer S-2S is being installed. S-2S was designed to achieve a high momentum resolution of Δp/p = 6 × 10−4 in FWHM. Several strangeness-physics programs which require the high resolution will be realized by S-2S. The present article introduces J-PARC E70 (missing-mass spectroscopy of Ξ12Be) and E94 (missing-mass spectroscopy of Λ7Li, Λ10B, and Λ12C) experiments.

In his History of Italy (XVIII, 7), Francesco Guicciardini celebrated his own role as saviour of the patria, i.e. of Florence, during the so-called Tumulto del venerdì, the failed anti-Medici coup of 26 April 1527. The forgotten testimony by the Urbino ambassador Orazio Floridi scales down the version of facts provided by Guicciardini, raising the question of the relationship between autobiography and historiography. This essay explores the double role of Guicciardini as papal Luogotenente and as Florentine citizen who was about to make the decision of aiding Florence while leaving open the way to the devastation of Rome. In his Accusatoria Guicciardini drew up charges against himself that, in the light of this contribution and of historical hindsight, seem more than grounded.

Abstract: Hybrid pixel and double sided silicon microstrip devices will equip the Micro Vertex Detector of the experiment. The most challenging request of the experiment is the continuous readout at the rate of interactions/s. The detector is in an advanced R&D phase and pixel assemblies, composed of thinned epitaxial sensor read out by the custom chip prototype ToPix, developed in the 130nm CMOS technology, were produced. The triggerless ASIC implements readout channels that are able to detect signals and transmit the information with a precise timestamp. It performs the energy loss measurement using the Time over Threshold technique, in the input range to about 50fC. A dedicated testing bench allows the control and the readout of each single chip assembly. Two experimental setups were assembled for testing these first single chip prototypes with pions at CERN, T9, in August 2012. The first one is based on a pixel assembly positioned in the middle of a telescope composed of double sided silicon strips sensors. A 50MHz clock signal synchronizes these two systems, the triggerless pixels and the strip detectors triggered by scintillation detectors. The second experimental setup is a tracking station housing four pixel assemblies. First results will be reported. [Copyright &y& Elsevier]
