A one-day event, by and for young researchers, organized by the Italian representatives of the ECFA Early Career Researcher (ECR) panel, aimed at bringing together for the first time the ECR Italian community on the occasion of the ECFA Plenary at LNF. The aim is to start a discussion about the future of our discipline, in the context of future accelerators and beyond, focusing on career paths and physics perspectives. Part of the event will be dedicated to building an Italian ECR network with the goal of informing, sparking discussion, and promoting constructive intergenerational dialogue ahead of the European Strategy. The organisation of a follow-up community event, planned for October, will also be discussed. Due to logistical considerations, only a few representatives per section have been invited, but the event is open to anyone who wishes to participate. Please register if you plan to attend online or in person. In the afternoon session, participants who wish to do so will be invited to present the activities of their laboratories in 2-3 slides that might be of interest for this meeting. The aim is to foster networking and awareness regarding the work of various groups, ideally having one representative per section. The idea is to have a series of flash presentations rather than a long list of contributions that would take up the entire day. Slides should be uploaded to the shared cernbox before Wednesday morning.

Speaker: Vincenzo Fiorentino (Padova Univ.) After reviewing the foundational aspects of quantum field theory at finite density, the talk will focus on themodifications of axion properties in systems at finite baryonic density. Those are especially relevant for highly dense stellar environments such as supernovae and neutron stars, which are typically employed to set stringent limits on axion couplings from anomalous stellar cooling. Specifically, we consider finite density modifications of axion couplings to nucleons within the framework of heavy baryon chiral perturbation theory and assess their consequences for astrophysical constraints on the axion parameter space. Moreover, we analyse the effect of finite density corrections on nucleophobic axion models, i.e. ultraviolet completions of the axion effective field theory in which the axion couplings to nucleons are suppressed. These models have the advantage of evading some of the astrophysical bounds on the axion parameter space. Since these bounds are obtained from highly dense systems, we question whether the nucleophobia condition is spoiled by finite density effects

The duration of the neutrino burst from the supernova event SN 1987A is known to be sensitive to exotic sources of cooling, such as axions radiated from the dense and hot hadronic matter thought to constitute the inner core of the supernova. We perform the first quantitative study of the role of hadronic matter beyond the first generation — in particular strange matter. We do so by consistently including the full baryon and meson octets, and computing axion emissivity induced from baryon-meson to baryon-axion scatterings as well as from baryon decays. We consider a range of supernova thermodynamic conditions, including equation-of-state models with different strangeness content, in order to make sure our results are robust. We obtain the first bound on the axial axion-strange-strange coupling, as well as the strongest existing bound on the axion-down-strange counterpart. Our bound on this coupling can be as small as O(10^−2) for the QCD axion, i.e. for an axion decay constant f_a = 10^9 GeV.  Join Zoom Meetinghttps://infn-it.zoom.us/j/98320147600?pwd=r7X6GpLqnWK9h9wnZKgj3g3ePNICEw.1Meeting ID: 983 2014 7600Passcode: 392002

STRONG-2020 offers an opportunity to cover local and travel expenses for young researchers.During the second and third days, invited speakers will present their work and perspectives in various areas of Hadron Physics and related fields.  The Workshop will be followed by the STRONG-2020 Annual Meeting organized in Frascati on 20-21 June 2024 and open to a large audience. The Agenda will be soon available and the Registration is possible at the dedicated site here.   This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 824093 

The aim of the “Exploring the Quantum Boundaries: an Odyssey into the gravity related collapse models” is to bring together theorists and experimentalists working in the field of quantum collapse models, in particular (but not limited to) gravity-related collapse, proposed as solution to the measurement problem in quantum physics, to discuss the present status of these models, both from theoretical and experimental points of view.On the theoretical side dissipative and non-Markovian collapse models are being developed and the interplay between gravity and collapse explored; at the same time, experimentalists search for signatures of the proposed models with various and very different physical systems. A discussion about the future in this field will be put forward involving experts and young researchers working in the field.The Workshop is organized with the support of the INFN-LNF, and of the John Templeton Foundation being the closing event for the QUBO JTF financed project (Grant 62099).Image Credit: Michal Bednarski for Quanta MagazineChairs:Catalina Curceanu, INFN-LNF, Frascati, ItalyLajos Diósi, Wigner Research Center for Physics and Eötvös Loránd University in Budapest, HungaryKristian Piscicchia, CREF, Rome, and INFN-LNF, Frascati, Italy Local Organizers:Simone Manti, INFN-LNF, Frascati, ItalyFabrizio Napolitano, INFN-LNF, Frascati, ItalyDiana Sirghi, CREF, Rome, and INFN-LNF, Frascati, ItalyFrancesco Sgaramella, INFN-LNF, Frascati, Italy Secretary:Alessandra Tamborrino Orsini, INFN-LNF, Frascati, Italy .     

Speaker: Alexander Lind (CNRS & Subatech Nantes) I will present recent work on an NLO study of the process pp -> ttbar in the 1-Higgs-singlet extension of the S with an additional heavy Higgs boson that mixes with the light Higgs boson.. This process is subject to large interference effects between loop-induced Higgs-mediated amplitudes and QCD continuum background. A reliable modelling of the resulting top-pair invariant-mass shapes requires the inclusion of higher-order QCD corrections. The computation of NLO corrections is exact in all contributions but in the class of non-factorisable two-loop diagrams, included in an approximate way which preserves all infrared singular limits. We present numerical results for several benchmark points with masses in the range 700-3000 GeV considering the production of stable top quarks. We find that the interference dominates the BSM signal yielding sharp dip structures instead of resonance peaks. The significance and excludability of the BSM effect is explored for the LHC Run 2, Run 3 and HL-LHC.

Information about the Higgs potential from the self-couplings of the detected Higgs boson is crucial for a better understanding of the mechanism of electroweak symmetry breaking and of the electroweak phase transition in the early Universe. The latter is of particular importance in the quest for explaining the observed asymmetry between matter and anti-matter in the Universe. It will be shown that although the present bounds on the trilinear Higgs self-coupling from Higgs pair production at the LHC are still relatively weak, they already provide a new way for probing so far unconstrained parameter regions of extended Higgs sectors. The parameter region of extended Higgs sectors giving rise to a strong first-order electroweak phase transition in the early Universe and potentially detectable gravitational wave signals is typically correlated with a certain mass splitting among the additional Higgs bosons, giving rise both to to a significant enhancement of the trilinear Higgs-boson self-coupling compared to the SM value and to a characteristic “smoking gun’’ signature in the search for additional Higgs boson. The prospects for exploiting the process of triple Higgs-boson production at the LHC for constraining both the trilinear and quartic Higgs boson self-couplings are briefly discussed. Join Zoom Meetinghttps://infn-it.zoom.us/j/96342145853?pwd=NzlkbUhPOTR4MmVFTXQ4dDhDK09lQT09Meeting ID: 963 4214 5853Passcode: 667657 

The 16th workshop on Shielding aspects of Accelerators, Targets and Irradiation Facilities (SATIF-16) will take place on May 28-31, 2024 at the National Laboratories of Frascati of the Italian National Institute for Nuclear Physics.The SATIF workshop aim is to promote information exchange among experts in the fields of radiation physics and the application of ionizing radiations in different fields of science and technology. This series workshops are experts’ meetings addressing important aspects related to the modeling and design of accelerator shielding, including updates on new and emerging features of the computation tools including FLUKA, MARS, and PHITS, high resolution radiological assessments for large scale areas with automated run-time optimization for the simulation of deep penetration of radiation in shielding structures, machine learning driven design optimizations, and comprehensive benchmarking exercises. Main objectives of SATIF meetings are:promoting the information exchange among experts in the field of accelerator shielding and related topics;identifying areas where international cooperation can be fruitful;creating task forces in order to achieve progress in specific priority areas. SATIF workshops have been held once every two years since 1994, rotating between the US, Europe, and Asia.
