In my talk I discuss on what is currently known on the theoretical interpretation of the top-quark mass parameter in Monte-Carlo event generators (MCs), as measured in the direct top-mass measurements. The interpretation is associated to the perturbative part of the MCs, namely the parton shower, as well as on the way howthe infrared evolution of the parton shower is terminated through thecutoff parameter. Nevertheless, also the hadronization modelplays an important role. This implies that, in order to solve the top-mass interpretation problem, the shower cutoff should be treated like a factorization scale and not like a tuned parameter. I explain the conceptual and practical implications of this rather novel view, and its interplay with the top-mass calibration method, which I have developed some time ago.    

The Stawell Underground Physics Laboratory (SUPL) is a newly built underground facility in regional Victoria, Australia. The laboratory is be located 1024 m underground (~2900 m water equivalent) within the Stawell Gold Mine and its construction has been completed in 2022/2023. The laboratory will house rare event physics searches, including the upcoming SABRE South dark matter experiment, as well as measurement facilities to support low background physics experiments and applications such as radiobiology and quantum computing. SABRE South will be the first experiment assembled in SUPL and its commissioning is expected to occur in 2023/2024. SABRE South is part of the SABRE experiment which aims to detect an annual rate modulation from dark matter interactions in ultra-high purity NaI(Tl) crystals in order to provide a model independent test of the signal observed by DAMA/LIBRA. SABRE South has different shielding design than SABRE North and it is designed to disentangle seasonal or site-related effects from the dark matter-like modulated signal by using an active veto and muon detection system.  Ultra-high purity NaI(Tl) crystals are immersed in a linear alkyl benzene (LAB) based liquid scintillator veto, further surrounded by passive steel and polyethylene shielding and a plastic scintillator muon veto. Significant work has been undertaken to understand and mitigate the background processes, that take into account radiation from the detector materials, from both intrinsic and cosmogenic activated processes, and to understand the performance of both the crystal and veto systems. This talk will report on the design of SUPL and on the status of the SABRE South assembly.

The Dark Energy from Fundamental Theories to Observations Conference will be held in the Bruno Touschek Auditorium (Bldg. 36, access from LNF secondary entrance in Via E. Fermi, 60 – see map).        (Talks by invitation only)You are welcome to download the conference poster here.Aim of the meeting:The problem of dark energy has unprecedentedly taken a central stage in the gravitation and cosmology research field, also in the view of the discrepancies found in the current expansion of the Universe as derived from Planck data and from local direct measurements. In this regard, we aim at organising an international workshop to discuss dark energy both from the theoretical and observational points of view. The workshop will be a precursor to the growing interest that this topic will gain in the near future due to the Euclid satellite, whose launch is planned for later this year, complementary ground-based observatories and Cosmic Microwave Background data. We would like to gather experts (both from the theory and observational sides) to understand together, through talks and discussion sessions, which predictions of fundamental theories can be tested by observations and, conversely, which new roads in fundamental physics may be opened by the future data. Important dates: May    1, 2023 –  Program announcement July    10, 2023 –  Deadline to apply for participation and poster presentationJuly    14, 2023 – Notification of acceptance of participation and postersOrganising Committee:Luca Buoninfante (Nordita) Alexey Koshelev (ShanghaiTech University, Shanghai & University of Beira Interior, Covilha) K.

The mini-workshop has the aim to gather experimentalists and theorists working in the field of exotic atoms, with particular application to kaonic atoms, to discuss the outcome of the ongoing experiments at DAFNE and plan future activities. The impact of kaonic atoms studies in particle and nuclear physics, as well as in astrophysics and foundation of physics will be addressed.The mini-workshop is organized with the support of the INFN-LNF, the Foundational Questions Institute (Grant No. FQXi-RFP-CPW-2008), the John Templeton Foundation (Grant 62099), the STRONG-2020 EU project (grant agreement No 824093), the MITIQO project n.
