The Hitchhiker’s Advanced Guide to Quantum Collapse Models and their impact in science, philosophy, technology and biology

                                                                                                 Image Credit: local_doctor/Shutterstock.com The aim of the workshop is to bring together theoreticians and experimentalists to discuss the present status of the collapse models, which were proposed as a solution of the measurement problem in quantum physics. A workshop as a Hitchhiker’s Advanced Guide to Quantum Collapse Models, both for experts and, especially, for the young participants. We witnessed lot of progress recently in the studies of the collapse models. On the theoretical side new realistic dissipative and non-Markovian collapse models are being developed, in order to provide a glimpse on the physical mechanism driving the collapse. At the same time, experimentalists search for signatures of the proposed models with various and very different physical systems. Searches of anomalous heating, or of spontaneous radiation are performed in atomic, nuclear, and mesoscopic/macroscopic systems from underground laboratories to (planned) space-based experiments, together with interference-based experiments. The workshop will bring together the communities working in quantum collapse with the aim to set up a synergetic effort towards progress in the field. Discussions of the impact of the collapse models in philosophy, technology and in biology, in particular the consciousness Orch OR model, will be stimulated. The workshop is organized with the support of the INFN-LNF, of the Foundational Questions Institute (Grants No. FQXi-RFP-CPW-2008 and FQXi-MGA-2102) and of the John Templeton Foundation (Grant 62099).   Symposium Chairs: Catalina Curceanu, Laboratori Nazionali di Frascati, INFN, Italy Maaneli Derakhshani, Rutgers University in New Brunswick, New Jersey, …

The U boson as a generalized dark photon, possibly also behaving as an axionlike particle

Could a new interaction exist in nature ?  Beyond weak, electromagnetic and strong interactions, it is natural to enquire about an additional one, associated with an extra-U(1) gauge group. The corresponding boson, called U forty years ago, may be (very) light, and (very) weakly coupled, its properties depending on m_U, the size of its coupling, and corresponding current (which depends on the BE-Higgs symmetry-breaking sector). Its vector part is a combination of electromagnetic with B and L (or B-L) currents. Axial couplings may also be present, which may make the spin-1 U boson interact much like a spin-0 axionlike particle. We discuss some of the effects of such a new boson, including its production in e+e- annihilations and beam dump experiments, ψ, Υ and K decays, parity-violation effects in atomic physics, anomalous magnetic moments of charged leptons, non-standard neutrino interactions, a possible “protophobic” behaviour suppressing π° -> γ U decays (related with a tentative interpretation of the Atomki anomaly). The U may also serve as a mediator to a new dark sector, allowing for thermally-produced light dark matter particles.

Brave New Worlds: The Discovery and Characterisation of Planets Beyond Our Solar System

Over the past three decades astronomers have discovered over 5000 planets orbiting distant stars – known as “exoplanets”. In this talk I will outline the ingenious methods that have been used to overcome the extreme challenges involved in finding these exoplanets. I will discuss the stunning variety of exoplanets that we have found, and what we have learnt from these discoveries. I will then discuss how we are able to learn more about these planets using observations that probe their orbits, temperatures, and even compositions. Finally I will finish by looking ahead to what the future might hold in terms of uncovering planets and even life beyond our Solar System.

XX FRASCATI SUMMER SCHOOL “BRUNO TOUSCHEK” in Nuclear, Subnuclear and Astroparticle Physics

The XX LNF Summer School “Bruno Touschek” in Nuclear, Subnuclear and Astroparticle Physics will take place at the INFN, Laboratori Nazionali di Frascati, Italy from Monday, July 11th to Friday, July 15th, 2022. The School is intended for graduate students and post-doctoral fellows in theoretical and experimental high-energy physics. The 2022 edition of the School includes lectures on selected theoretical and experimental topics, discussion sessions, and the 7th Young Researchers Workshop on `Physics Challenges in the LHC Era’, which will take place on Monday, July 11th and on Thursday, July 14th. Students planning to participate in the School are strongly encouraged to apply to give a presentation of their research in the workshop, by sending an email to gennaro.corcella@lnf.infn.it, with a copy to school@lnf.infn.it, with the proposed talk title. The contributions will be published in Frascati Physics Series. A few fellowships covering the registration fee and/or accommodation are available for selected participants giving talks.

AARP – XlabF: Compact Solutions for Future Advanced X-ray Studies

L’XLab Frascati, presente all’interno dei Laboratori Nazionali di Frascati e specializzato nell’uso di tecniche spettroscopiche di raggi X e nella produzione e caratterizzazione di ottiche per raggi X (ottiche policapillari), apre le sue porte fisiche e virtuali ai ricercatori e alle ricercatrici durante la giornata di workshop dal titolo “AARP – XlabF: Compact Solutions for Future Advanced X-ray Studies”. Partendo da piccole semplici applicazioni, ideate dalla collaborazione del Prof. Sultan Dabagov con il Dr. Giorgio Cappuccio ormai diverso tempo fa, di una tecnologia all’epoca poco conosciuta in Italia, ossia le ottiche policapillari, si è oggi arrivati ad un laboratorio dedicato sia alle tecnologie di innovazione basate sulla realizzazione e produzione di lenti policapillari, che alle metodiche di analisi basate sui raggi X. Oggi, l’XLab Frascati (o più semplicemente XlabF) rappresenta una facility che dispone di strumentazione per lo studio di tipo cristallografico, spettroscopico e tomografico, grazie a 3 apparati strumentali perfettamente funzionanti e a disposizione di utenti locali ed esterni con i quali  è possibile ottenere informazioni di imaging ad elevata risoluzione, micro-tomografia, micro-fluorescenza 2D e 3D, diffrazione e test di diagnostica di sorgenti, ottiche e rivelatori di nuova generazione. Tutto questo è stato reso possibile grazie anche alle numerose collaborazioni con colleghi sparsi in tutta Italia e nel mondo in ambiti tra i più disparati quali l’elettronica, i beni culturali, l’archeologia, la dendrologia per citarne alcuni. Ed è proprio la volontà di mantenere vivo questo intreccio di competenze nonché di creare nuove sinergie tra i partecipanti ed uditori del workshop che …
