    Deuteron-Ξ correlation function studied with three-body model

    Full text link
    Many-baryon forces play a crucial role in shaping the structure and dynamics of many-baryon systems. Utilizing three-body correlation functions in femtoscopy offers a promising tool for probing three-baryon forces. However, the dynamics of three-body systems necessary for obtaining these correlation functions remains incompletely understood. In this study, we employ the continuum-discretized coupled channels method, a precise and cost-effective three-body model, to explore the influence of deuteron excitation to its continuum states on the deuteron-Ξ correlation function. Our findings reveal that the deuteron-Ξ interaction derived from lattice quantum chromodynamics does not yield a bound state. Moreover, we determine that the effect of deuteron excitation leads to less than a 10% increase in the correlation function, suggesting the predominance of direct deuteron formation through heavy-ion collisions. Overall, our work lays the groundwork for further investigations aimed at elucidating many-baryon forces

    Recent results and highlights from the CHIMERA Collaboration

    Full text link
    The CHIMERA Collaboration uses three main devices in its experimental activities: the CHIMERA 4π detector, the FARCOS correlator (Femtoscope Array for Correlation and Spectroscopy) and the new NARCOS plastic scintillators array prototype for neutrons and light charged particles detection. We discuss two recent examples of physics results obtained with these devices: the first one will focus on the AsyEos-II experiment that studies the EoS (Equation-of-State) of neutron rich matter at high baryon densities. The AsyEos-II experiment will be realized in 2025 at GSI/FAIR and it proposes to probe the EoS at densities around 2ρ0 in Au+Au collisions and beam incident energies from 250 to 800MeV/A. The second one, in the Fermi energy regime, studies dynamical emission of particles at 20MeV/A beam energy as a function of projectile and target isospin (CHIFAR experiment). Contributions of the CHIMERA Collaboration for the diagnostic and tagging system of the FraISe facility at LNS based on SiC (Silicon Carbide) technology and recent advances of the NARCOS array project will be briefly discussed

    Charged-particle identification with advanced artificial intelligence approaches

    Full text link
    Modern nucleus-nucleus collision experiments require the use of advanced particle identification techniques. However, similar tasks are often time-consuming, enhancing the complexity of the data analysis process. We develop a novel approach capable to automatically identify charge and mass of detected ions with almost zero human supervision. Our method uses evolutionary computing and clustering algorithms and exploits previously developed analytical functionals to provide physics constraints. The new algorithm is successfully tested on ΔE-E telescopes based on annular silicon strip detectors and could be integrated in online and offline analysis pipelines of existing detection arrays

    Development of a SiC detector array within the SAMOTHRACE ecosystem

    Full text link
    In recent years, the scientific community has shown an increasing interest in utilizing SiC-based particle detectors, particularly for investigations in nuclear and medical physics. This growing interest is driven largely by the remarkable properties of SiC, combined with advancements in device fabrication techniques. Within the SAMOTHRACE ecosystem —which focuses also on developing new-generation SiC-based detectors— significant progress has been made in characterizing these detectors for their use in both medical and nuclear physics. This contribution presents some of the key results obtained from this characterization process by means of first tests using radioactive α sources

    Impact of the pixelation method on the FARCOS telescope performances

    Full text link
    In this contribution, the results achieved using the pixelation method for the FARCOS array will be presented. The α coincidence data in events produced in the reaction 16O+12C will be analysed. A good energy resolution has been obtained in the reconstruction of the excitation energy of the populated resonances. The correction of inter-strip effects and the accurate reconstruction of the detection angles, also in events with 3 or more touched strips, improves the detection efficiency

    The environmental issues threatening our society and the optimization of ecosystem services are among the most pressing challenges that require immediate attention and actions. Climate change, biodiversity loss, deforestation, environmental pollution, and soil degradation are just some of the crucial issues that our society is facing now and for the future decades. While some progress towards environmental target have been achieved, more efforts are needed to reach climate neutrality, reduce pollution and preserve biodiversity. Environmental challenges are strictly related to the sustainability concept, representing the intersection point of social, environmental, and economic needs: an interdisciplinary strategy that integrates conservation, sustainable development, ecological resilience, and optimization of ecosystem functionality is needed to face these issues. In this context, national and international research networks and infrastructures play a crucial role to advance the scientific knowledge and provide practical solutions to the policy makers. The multidisciplinary approach of environmental research has been the main theme of the CNR-IRET 2025 Conference dedicated to highlight the Institute’s most recent projects, including those within the National Recovery and Resilience Plan (PNRR) and other national and international initiatives. The event has provided a valuable opportunity for dialogue, fostering interaction among different research groups and the entire scientific community. The exchange of ideas, experiences, and best practices emerged during the conference aimed at shaping the future of environmental sustainability. Key topics included habitat restoration, the integration of technologies in environmental management, global and local biogeochemical cycles, and the One Health approach. This Abstract Book serves as an invitation to reflection and action, with the awareness that only through a collective commitment we can ensure the protection and well-being of ecosystems

    Notiziario dei Metodi Analitici & IRSA News

    Full text link
    Il Notiziario dell’IRSA, grazie ad un approccio multidisciplinare, si propone come uno strumento snello e allo stesso tempo approfondito, volto a rispondere alle sfide legate alla scarsità delle risorse, valorizzando l’interazione tra le diverse discipline coinvolte, come la scienza, la tecnologia e la gestione ambientale. Questo secondo fascicolo del 2025 contiene quattro articoli che, riflettendo la multidisciplinarità dell'Istituto, si allineano con le tematiche sopradescritte, offrendo significativi contributi. Il primo propone lo sviluppo di protocolli e strategie di monitoraggio del più grande bivalve presente nel Mar Mediterraneo, Pinna nobilis, specie protetta che svolge importanti funzioni ecologiche, e che purtroppo si sta estinguendo nei nostri mari. Il secondo contributo riporta una metodica avanzata, sviluppata dall’IRSA, per la caratterizzazione tassonomica e funzionale della biomassa di acque reflue e fanghi attivi, al fine di verificarne le capacità metaboliche. Tali capacità sono fondamentali per attestare il corretto trattamento delle acque reflue prima del loro rilascio in natura, in quanto permettono l'eliminazione o la forte riduzione degli inquinanti. I due articoli successivi approfondiscono il tema dei contaminanti emergenti, quali gli antibiotici e i geni della resistenza, in qualità di inquinanti ambientali. Tali articoli ben si collocano nel contesto della World AMR Awareness Week (18-24 novembre 2025, https://www.who.int/campaigns/world-amr-awareness-week/2025), organizzata ogni anno dall’OMS che quest’anno ha per tema “Act Now: Protect Our Present, Secure Our Future” ed il cui scopo è quello di aumentare la consapevolezza della resistenza antimicrobica e promuovere le migliori pratiche per ridurre l’emergenza e la diffusione di infezioni resistenti agli antibiotici, in una prospettiva One health, che dunque coinvolge l’ambiente come uno dei tre fattori collegati insieme alla salute dell’uomo e degli animali. Non di poco conto poi le News, che riportano le attività ed alcuni progetti dell’Istituto, che vanno circolarizzati per una loro ulteriore valorizzazione e conoscenza, nonché per fungere da stimolo per iniziative future. Si è certi che il Notiziario dia un contributo rilevante nel comunicare riflessioni scientifiche e raccogliere le iniziative, italiane ed internazionali, sulle attuali sfide ambientali. Buona lettura

    Diritti e città in cammino. Profili di comparazione tra Italia e Argentina. Il diritto alla città tra gemelli digitali urbani e diritti individualiDiritti e città in cammino. Profili di comparazione tra Italia e Argentina. Il diritto alla città tra gemelli digitali urbani e diritti individuali

    Il libro affronta il tema del diritto alla città mettendo a confronto l’esperienza italiana relativa alla creazione di gemelli digitali urbani e quella argentina come strumento di governance urbana della città di Buenos Aires. In alcune realtà il concetto serve come espressione giuridicamente rilevante delle rivendicazioni collettive dei residenti nei quartieri popolari (o insediamenti informali, come vengono descritti in termini più burocratici) per la loro giusta integrazione nella città formale su un piano di parità, come ci dimostra l’esperienza della Città di Buenos Aires. Dall’altro lato, i gemelli digitali urbani possono essere uno strumento prezioso per promuovere l'impegno attivo dei cittadini che sfruttando la tecnologia possono migliorare la vita urbana e la gestione delle risorse ed elevare la qualità complessiva della vita della popolazione. Questo apre la strada a una nuova concezione della cittadinanza attiva e supporta una progettazione e una gestione urbana efficace

    Storia dell’informatica italiana. Prima parte. Ricerca, formazione e impatto sociale (3 voll.)

    Full text link
    Nata da un’idea del gruppo di lavoro AICA sulla Storia dell’Informatica, quest’opera monumentale – articolata in due parti, la prima composta da tre volumi e la seconda da due – ricostruisce, per la prima volta in modo organico, l’evoluzione scientifica, tecnologica e culturale dell’Informatica nel nostro Paese. Si tratta di un viaggio che parte dagli anni Quaranta e arriva ai primi Duemila, raccontato direttamente da chi quell’evoluzione l’ha progettata, costruita e vissuta. Si tratta di un imponente lavoro frutto della memoria collettiva e della ricostruzione storica e rigorosa operata da decine di studiosi, ricercatori, pionieri del settore e protagonisti dell’innovazione italiana coordinati con cura e passione da Maristella Agosti e Virginio Cantoni. L’opera ripercorre i grandi momenti fondativi: dai primi istituti del CNR all’epopea della CEP, dal Progetto Finalizzato Informatica alla nascita di Internet in Italia. Un lavoro unico che offre uno sguardo lucido sulle scelte strategiche, sulle occasioni mancate, sulle collaborazioni decisive e sul ruolo dell’informatica nella società contemporanea
