Fundamental Physics at the strangeness frontier at DAΦNE

The DAΦNE electron-positron collider at the Laboratories of Frascati, INFN-LNF, is a unique facility in the world to perform strangeness physics experimental studies with low-energy charged (and neutral) kaon mesons. Experiments measuring kaonic atoms transitions have been realized at DAΦNE in the last 25 years, with DEAR and SIDDHARTA which performed unique measurements on light kaonic atom transitions, such as the most precise kaonic hydrogen measurement and the first kaonic-helium3 transitions measurement. Presently SIDDHARTA-2, installed on DAΦNE, is aiming to perform the first kaonic deuterium measurement. The broad international scientific community involved in low-energy strangeness studies is envisaging and proposing new fundamental measurements using the unique kaon beams at DAΦNE. New experimental breakthroughs, parallelized by theoretical progress, can bring us into a new era in the strangeness physics studies with an impact extending from fundamental physics to astrophysics and beyond. These two-days workshop is devoted to discuss a road-map for the experiments to be proposed at DAΦNE for the next 5 years time window to start after the end of SIDDHARTA-2 run.   Organizing Committee: C.

Dispersive study of pion-kaon scattering: the kappa and other strange resonances and threshold parameters

We have recently completed the coupled dispersive analysis of  pi pi -> K anti-K We show that just fitting data fails to satisfy the dispersive representation and leads to inconsistencies with threshold sum-rules as well as unreliable resonance parameterizations. Our main result is a set of constrained fits to data that satisfy 16 dispersion relations of different kinds and allow for a reliable extraction of threshold and subtreshold parameters to be compared with Chiral Perturbation Theory and lattice QCD. In addition, we obtain a precise dispersive determination of the controversial light kappa-meson parameters, which has therefore become a “confirmed” state in the PDG, completing the light meson scalar nonet. The constrained fits to data are easy to implement and ready for further theoretical and experimental studies.

The Borexino heritage: pp and CNO fusion processes in the Sun

The Borexino collaboration has recently completed the study of solar neutrinos by detecting the CNO cycle. Such process, though sub-dominant in the Sun, plays a key role in the Universe and its detection represents a substantial experimental achievement. The seminar will review the main experimental challenges faced faced to achieve the measurement. It will also summarise the various and rich results obtained by Borexino in its 13 years of data taking.

SICURA Day: Metodi innovativi per la sicurezza radiologica. Presentazione del sistema SICURA

Overview SICURA Day è’ l’evento online conclusivo del progetto SICURA, finanziato dalla Regione Lazio nell’ambito del bando L.R. 13/2008 – art.4 “Progetti di Gruppi di Ricerca, Conoscenza e Cooperazione per un Nuovo Modello di Sviluppo”. Si tratta di una giornata dedicata alla presentazione del progetto, dei risultati conseguiti e alla discussione circa i suoi possibili utilizzi in vari ambiti. Il progetto, iniziato a Novembre 2018, riguarda lo sviluppo di una sonda portatile integrata e a basso costo, in grado di rivelare la presenza di sostanze radioattive emittenti raggi gamma e/o neutroni. La sonda SICURA rappresenta un utilissimo strumento di sicurezza impiegabile, ad esempio, nei controlli presso potenziali obiettivi terroristici, come aeroporti, piazze, scuole, università, centri commerciali, ecc. Dotata di capacità identificativa ed elevata sensibilità, la sonda può essere utilizzata anche nel monitoraggio radiometrico presso ospedali, discariche, inceneritori, controllo di rottami o semilavorati, centri di ricerca e impianti nucleari. All’evento, durante il quale si presenterà il progetto SICURA e di dimostreranno le funzionalità dell’omonima sonda, sono invitati a partecipare rappresentanti di piccole e medie imprese della Regione Lazio, che producono strumenti utilizzati per la rivelazione della radiazione, nonché potenziali soggetti interessati all’utilizzo dello strumento in vari ambiti, quali i controlli di sicurezza, il monitoraggio industriale, e la radioprotezione negli ospedali. La partecipazione all’evento è estesa alle imprese del settore, agli stakeholder istituzionali, ai professionisti della sicurezza e della radioprotezione, all’INFN e agli enti di ricerca affini. Seguiranno dettagli organizzativi.

A primary electron beam facility at CERN — eSPS

The design of a primary electron beam facility at CERN will be described. It re-enables the Super Proton Synchrotron (SPS) as an electron accelerator, and leverages the development invested in Compact Linear Collider (CLIC) technology for its injector and as an accelerator research and development infrastructure. This would be a facility relevant for several of the key priorities in the 2020 update of the European Strategy for Particle Physics, such as an electron-positron Higgs factory, accelerator R&D, dark sector physics, and neutrino physics. In addition, it could serve experiments in nuclear physics. The electron beam delivered by this facility would provide access to light dark matter production significantly beyond the targets predicted by a thermal dark matter origin, and for the nature of dark matter particles that are not accessible by direct detection experiments. It would also enable electro-nuclear measurements crucial for precise modelling the energy dependence of neutrino-nucleus interactions, which is needed to precisely measure neutrino oscillations as a function of energy. The facility is a natural next step in the development of X-band high-gradient acceleration technology as pursued within the CLIC collaboration. The facility also allows studies of a number of components and phenomena for a future electron-positron Higgs and electroweak factory as the first stage of a next circular collider at CERN, and its cavities in the SPS would be the same type as foreseen for such a future collider. It’s X-band injector linac would become a facility with multi-GeV drive bunches and truly independent electron witness ...

The FASER experiment at the CERN LHC: Looking forward to new physics

The FASER experiment is a new small and inexpensive experiment that will be placed 500 meters downstream of the ATLAS experiment at the CERN LHC. The experiment will shed light on currently unexplored phenomena, having the potential to make a revolutionary discovery. FASER is designed to capture decays of exotic particles, produced in the very forward region, out of the ATLAS detector acceptance. FASERnu, a recently proposed FASER sub-detector, is designed to detect collider neutrinos for the first time and study their properties. FASER was approved by CERN in 2019, with the FASERnu detector approved at the end of 2019. This seminar will present the physics prospects, the detector design, and the construction progress of FASER. The experiment is on track to be installed by early 2021 and to take data during the LHC Run-3, starting in 2022.

Experimental searches for axions

Proposed more than 40 years ago, axions are still the most compelling solution to the strong CP problem of the Standard Model. More recently their physics case has been considerably sharpened, as well as that of similar axion-like particles (ALPs) that generically emerge in diverse high-energy extensions of the Standard Model, notably string theory. Both axion and ALPs constitute very appealing candidates to the dark matter of the Universe, and they are also invoked as a solution of a number of anomalous astrophysical observations. In addition, particular realizations of these type of models appear linked with inflation, dark radiation and even dark energy. These developments, together with the fact that experimental techniques have recently achieved sensitivity to relevant regions of ALP parameter space, are increasing the interest in the search for these particles. I will review the status of the experimental landscape, as well as near term prospect from ongoing experiments, future projects and new detection ideas in the search for laboratory, dark matter and solar axions and ALPs.
