  Yang-Mills fields present scale invariance, what allows the theory to be renormalized. In this talk we show that fractal structures can be formed by fields described by this theory. Such fractal structure allow for recursive equations that enable the calculation of high order perturbative calculations. In addition, it leads to  power-law distributions of energy and momentum, and therefore explains the emergence of the non extensive Tsallis statistics in high energy physics and in hadron physics. Similarities with the concept of thermofractal, recently introduded, are discussed, as well as comparison with experiments.

SICURA: il progetto LNF che ha vinto il bando della Regione Lazio per Progetti di Gruppi di ricerca Verrà presentato il progetto SICURA (SICUrezza RAdiologica), una proposta innovativa elaborata da Catalina Curceanu e da Roberto Bedogni che ha vinto il bando della Regione Lazio per Progetti di Gruppi di ricerca – Conoscenza e Cooperazione per un Nuovo Modello di Sviluppo. Gli elementi chiave del progetto, che si inserisce negli ambiti della sicurezza radiologica e lotta al terrorismo, sono l’impiego di sensori a basso costo e la loro integrazione mirata a rivelare simultaneamente radiazioni X, gamma e neutroni, per la realizzazione di una sonda portatile per operare nell’ambito dei controlli di sicurezza e di ordine pubblico. Grazie all’elevata capacità di interconnessione, con la sonda SICURA si potranno monitorare, in tempo reale, scenari come piazze, scuole, eventi sportivi, concerti o centri commerciali.. Il seminario illustrerà il layout preliminare del sistema di misura SICURA, le sue peculiarità rispetto a sistemi commercialmente disponibili, ed i requisiti a cui dovrà rispondere.

To decisively upgrade the luminosity of the LHC, and increase its Physics reach, the High Luminosity LHC project is opening a new territory, developing a broad range of new technologies: accelerator magnets in the 12 tesla range based on advanced Nb3Sn technology, long superconducting links rated for 100 kA with novel MgB2 superconductors, new type of SRF cavities, etc…. The talk will discuss the status of these new technologies for HL-LHC and especially the high field magnets, now at the verge of entering into production, as well as the studies under way for the post-LHC Hadron Collider. In particular, for the FCC stronger Nb3Sn magnets, for 16 T, are under design and the first R&D on HTS (High Temperature Superconductors) accelerator magnets has started. HTS magnet results are promising to open the 20 T range, which would bring the 100 km FCC even beyond the 100 TeV threshold.

The aim of the "Low-energy strangeness studies ad DAFNE and J-PARC" workshop is to give an outline of the major issues in the low energy strangeness nuclear physics sector and to discuss still open problems to be addressed in the near future.    The low energy strangeness QCD represents one of the most interesting sectors in physics,the existence of broad hyperon resonances just below the Kbar-N threshold, like the debated Lambda* state, makes the  Kbar-N  interaction a complicated non-perturbative and multi-channel problem which puzzled theoreticians and experimentalists for decades.   The accurate investigation of the Kbar-N and Hyperons-N interaction above, below and at the threshold deeply impacts many sectors of physics ranging from nuclear physics to astrophysics.    The workshop is organized in the framework of the StrangeMatter Italy-Japan project supported by the Ministero degli Affari Esteri e della Collaborazione Internazionale (MAECI) and is sponsored by the Istituto Nazionale di Fisica Nucleare and by the CENTRO FERMI – Museo Storico della Fisica e Centro Studi e Ricerche Enrico Fermi.

This talk reviews the recent activities carried out at CERN in terms of transverse beam splitting with proton beams. Thanks to intense experimental and theoretical activities, the recently-proposed approach of splitting beams in the horizontal phase space using stable islands moved out of the test stage to beoame a mature technique of beam manipulation to perform multi-turn extraction. It is therefore timely to address the question whether stable islands can be applied to other branches of accelerator physics, in view of bringing new means of improving ring’s performance. This is the case of synchrotron light machines, where the use of stable islands could lead to new developments that will be presented and discussed.

The NEXT Nanotechnology group at INFN – LNF organizes since 2000 a series of international meetings in the area of nanotechnology. The conference in 2018 is devoted to recent developments in nanoscience and its manifold technological applications. It consists of a number of tutorial/keynote lectures, as well as research talks presenting frontier nanoscience research developments and innovative nanotechnologies in the areas of biology, medicine, aerospace, optoelectronics, energy, materials and characterizations, low-dimensional nanostructures and devices. We plan to submit selected papers, based on conference talks and related discussions, for publication on a dedicated issue of a MDPI journal (to be specified later). There will be Invited Lecturers and selected talks from the call for papers below, as well as a poster session. CALL FOR CONTRIBUTIONS Authors wishing to submit their work for presentation at the conference can send an abstract as a doc or pdf file (max. 3 pages) to bellucci@lnf.infn.it by 5th December 2018, specifying whether it is meant for oral or poster presentation. Authors will be notified of the acceptance of their submission by 7th December 2018. LOC: S. Bellucci (Chair), S. Bistarelli, O. Calamai, A. Cataldo, F. Micciulla, M. Regi IAC: G.
