An outlook on the relevant progresses in the rhenium experiment with cryogenic detectors that has been made in the past year will be presented. We will discuss how the surrounding environment causes a ripple-like perturbation on the energy spectrum called Beta Environmental Fine Structure (BEFS). In 3 months of effective data acquisition we...

Determining whether neutrinos have mass is an important test of grand unified theories. Neutrino masses can in principle be measured from small distortions' in the spectra of electrons emitted in low-energy beta-decay processes. Detailed knowledge of the beta-particles' spectral shape and the detector response is therefore required in order to...

We propose a parametrization for intepreting some of the presently available data of the B+/- -> K+/-p pbar decay, in particular those by LHCb and Belle collaborations. The model is inspired to the well-known current and transition contributions, usually assumed in this kind of decay. However, in the light of considerations about the dominant...

The LHCb experiment at CERN has a large number of custom electronics boards performing high-speed data-processing. As in any large experiment the control and monitoring of these crate-mounted boards must be integrated into the overall control-system. Traditionally this has been done by using buses on the back-plane of the crates, such as VME....

Descrizione dell'interfacciamento di un PC di dimensioni molto piccole (formato "Carta di Credito") con una scheda di elettronica, sulla quale il PC e` installato, in modo da poterne permettere il controllo remoto attraverso una rete ethernet. Allo scopo e` stata realizzata una scheda di interfacciamento, detta "Glue-Card", installata sulla...

The Focal Surface detector of EUSO (Extreme Universe Space Observatory) consists of small autonomous functional units (elementary cell, EC) assembled in larger modules (Photo Detector Modules, PDM). Each EC is conceived as an array of 4 multianode photomultipliers (MAPMTs). We have developed EC structure for the current baseline of the...
