Belle II status and prospects
Get PDFThis paper is intended to describe the Belle II experiment, its status and physics prospects. Belle II is situated in Japan, at the KEK Laboratory and it is the upgraded version of the Belle experiment. It uses a new collider named
SuperKEKB, a new generation of B-factory based on the innovative Nano-Beam scheme technique, which is expected to collect an integrated luminosity of 50 ab−1. Using this huge amount of data, together with improved detector performances, it will be possible to provide important contributions about several flavour physics topics (i.e., UT angles, CKM matrix elements, FCNC processes, LFV studies, etc.) through high-precision measurements, in order to investigate new physics scenarios and validate highly suppressed SM predictions. The experiment took the first data without the vertex detector in place while the data taking will start in February 2019
Accurate predictions for top-quark pair production at the LHC
Get PDFThe top quark is the heaviest elementary particle in the Standard Model. For this reason, a precise determination of its mass mt is part of the LHC physics program. The most accurate determinations of mt rely on the kinematic
reconstruction of the top decay products and on the use of Monte Carlo event generators. In this contribution I discuss the impact of different theoretical descriptions for the process of top-pair production at the LHC on the extraction of mt
Search for electroweak production of supersymmetric particles at LHC Run 2 with the ATLAS detector
Get PDFSearches for supersymmetric particles performed with the ATLAS detector 2015–2016 data will be presented. The physical processes considered are the electroweak production of charginos, neutralinos and sleptons, with final states with leptons and missing transverse energy. No excess above the Standard Model expectations was observed. Exclusion limits at 95% confidence level are reported
Results from AMS-02 on the ISS after 6 years in space
Get PDFAMS-02 is a cosmic-ray detector which has been operating on the International Space Station since May 2011 to conduct a unique mission of fundamental research in space. More than 100 billion cosmic rays have been collected by AMS-02 after 6 years of operations, providing a detailed insight into the features of different species of cosmic rays. This contribution reviews the recent AMS-02 results based on 6 years of operations in space and their contribution to the advances in the understanding of cosmic-ray origin, acceleration and propagation physics
The πLUP project: Exploiting new techniques and neural networks in high-energy experiment data acquisition
Get PDFThe constant challenge to break the frontiers of energy and luminosity in high-energy physics experiments at LHC brings along the necessity of constant technological efforts in the acquisition of the signal generated by particles
detectors. The relatively slow pace of the technological advance when compared to the constant increase of the outcoming bandwidth from the detectors requires the exploit of innovative methods and architectures for the data acquisition electronics. The πLUP project aims to create the prototype of a new generation of flexible data
acquisition boards by exploiting the capabilities of the FPGA technology combined with the ease of use of an integrated Linux kernel, in order to implement new technological paradigms and to study the impact of neural networks in the reconstruction of acquired data
The Beam Dump eXperiment
Get PDFThe Beam Dump eXperiment (BDX), proposed at Jefferson Lab
(JLab), will search for Light Dark Matter (LDM) particles in the Dark Photon scenario. In this model, the LDM interacts with the Standard Model via a new massive vector boson (Dark Photon or A). The experiment uses the CEBAF (Continuous Electron Beam Accelerator Facility) 11 GeV electron beam impinging on the JLab Hall-A beam-dump, to produce a beam of LDM particles, detected by a ∼ m3 detector placed ∼ 20 m downstream. Receiving 1022 electrons on target in 285 days, the BDX will exceed the discovery potential of all existing experiments in the MeV-GeV LDM mass range
Thermodynamic thresholds in water/methanol solutions
Get PDFThe non-ideality of water/methanol solutions is established by the interplay between hydrophilic and hydrophobic interactions that take place within the system and determine its physical properties. These interactions have a different energetic dependence on the temperature and the measurement of transport parameters, such as self-diffusion coefficient and relaxation time, allows to obtain important information about that dependence. Here it is shown how thermodynamic parameters such as temperature and concentration determine the character and the physical properties of the solutions. Furthermore, the thermodynamic thresholds that separate the different energetic regions were identified
Ambiente e cultura in alcune proposte per lo sviluppo locale e turistico delle aree periferiche del Mezzogiorno: un'applicazione didattica
Get PDFThe contribution aims to assess the interconnections between environment and cultural
heritage, aspects recently highlighted by the international community that recognized
the strategic role of cultural heritage for sustainable development, affirming the need
for a new mix between tradition (material and intangible cultural heritage), and
innovation for the resilience of communities against environmental disasters and
climate change, also considering the importance of disadvantaged and peripheral areas,
to achieve local development and tourism, adopting an integrated and sustainable
political approach that takes into account cultural, biological aspects, geological and
landscape. The first experience refers to the planning of the Structural Funds (2007-
2013) and to the European Regional Development Fund of the Puglia Region, with the
creation of SAC (Environmental and Cultural Systems). The choice was made on the
basis of the results obtained, as evidenced by the visits on the ground with students of
the Human Geography Course (a.y. 2017/2018), of the University of Bari Aldo Moro
and from meetings with the operators. The second research experience, also didactic,
concerns the city of Taranto for the enhancement of natural and cultural aspects, and
for a new approach related to tourism development, included as an application in the
Geography of Tourism course (a.y. 2018/2019) of the same University
Birra Funzionale™
Get PDFLa birra, come prodotto completamente naturale, appartiene ad un gruppo speciale di bevande alcoliche a basso contenuto alcolico. È ricca di sostanze nutritive con proprietà funzionali ben definite. Contiene carboidrati, amminoacidi, vitamine, acidi organici, composti fenolici, componenti antiossidanti del luppolo, orzo, malto d’orzo e lievito: ingredienti specifici con effetti potenzialmente benefici sull’organismo umano. La ricerca sulla capacità antiossidante e funzionale delle birre in tutto il mondo è limitata. Le birre rappresentano circa la metà del mercato di bevande alcoliche e contribuiscono in modo significativo all'assunzione di antiossidanti nella dieta. I principali antiossidanti sono: composti fenolici e componenti del luppolo e malto. Il mio studio e la mia ricerca si basano su indicazioni e motivazioni sufficienti per indagare il ruolo specifico della birra nella prevenzione della salute e delle malattie come “Birra Funzionale
Introductory Chapter: An Introduction to the Stratigraphic Setting of Paleozoic to Miocene Deposits Based on Paleoecology, Facies Analysis, Chemostratigraphy, and Chronostratigraphy - Concepts and Meanings
Get PDFThis is the introductory chapter of the book “New insights into the stratigraphic
setting of Paleozoic to Miocene deposits: case studies from the Persian Gulf,
Peninsular Malaysia and south-eastern Pyrenees.” In this chapter, the research
themes studied in this book have been introduced referring to the paleoecological
and facies analysis techniques
and methodologies, pertaining, in particular,
an Oligo-Miocene carbonate succession of the Persian
Gulf (Asmari Formation), the chemostratigraphy of Paleozoic
carbonates of Peninsular Malaysia through the integration
of stratigraphic, sedimentologic, and geochemical
data, and the chronostratigraphy of a small ice-dammed paleolake in Andorra, applying the FFT (Fast Fourier Transform) analysis, resulting
in sixth-order stratigraphic cycles, which have outlined
the occurrence of glacially controlled system tracts
and unconformities
