🗞 Hot off the press: Our Interim report marks an important step in defining the input on the chapter about muon colliders in the upcoming European Strategy for Particle Physics' Accelerator R&D Roadmap and highlights our progress towards the Muon Collider since 2020 and what we expect to achieve by 2026!

"It is true, that whenever ordinary light strikes an object, the collision gives rise to a small force on the object. This force is called radiation pressure." Read the article 'The Pressure of Laser Light', published #OTD in 1972 by physicist Arthur Ashkin. Ashkin was awarded the 2018 physics prize “for the optical tweezers and their application to biological systems." At the time of the award, he was 96 years old.

The NA62 experiment at CERN has observed the decay of a charged kaon into a charged pion and a neutrino-antineutrino pair! This decay is one of the rarest processes ever observed in the so-called flavor physics: according to the Standard Model, fewer than one in 10 billion charged kaons decay into these particles! Check out this article by INFN explaining all the details about the event here: https://lnkd.in/d4VaHeNJ #cern #infn #rarity #standardmodel #experiment

Yesterday, we finished a bit more than a standard beamtime. Did you know that ReMade@ARI can support your research in Circular Economy at every stage from materials' manufacturing to advanced characterization at neutron and synchrotron sources? In this project, I was honored to collaborate with Helmholtz-Zentrum Dresden-Rossendorf (HZDR) where the ion beam modification of GaAs substrates was made with subsequent deposition of metal and metal-oxide active layers. A dedicated operando cell designed at PSI Paul Scherrer Institut allowed us to perform XAS experiment in grazing incidence geometry at DESY. Complementary AFM and STEM measurements are also provided in frame of ReMade project. By the way, today is the deadline for Call IV of ReMade@ARI. Next call opens in spring 2025. One proposal = complete investigation. #catalysis #circulareconomy #ionbeam #beamtime #xrays #synchrotron

The precise measurement of the W boson’s mass is a significant milestone in particle physics. By connecting it to the three laws of Noah’s Ark Technology, we can envision a deeper understanding of universal symmetry, the connections between time and space, and the unification of fundamental forces, especially in extreme environments like those observed in LHC collisions. This approach paves the way for new ways to explore the very foundations of the universe, an objective at the heart of Noah’s Ark Technology.

It’s paper day. Our new FIREbox-HR simulation explains the elevated UV luminosity density seen by JWST. With FIRE physics, we predict a non-evolving, weakly-mass dependent star formation efficiency, alleviating the need to invoke weird baryonic physics or non-LCDM cosmology. 🔥 📦 🌌 https://lnkd.in/eTDxB5Wi

For Multipactor Aficionados, Just wanted to share our recent exciting discoveries in multipactor prediction and mitigation, now published in Physics of Plasmas. Building upon our in-house developed model, we've predicted a slightly different picture of multipactor susceptibility zones. The multipactor zones can extend into much higher frequency-gap distance regions, suggesting the feasibility of fast, millimeter-wave multipactor occurrences within reasonable gap distances (e.g., 3 mm). Looking forward to a champion that can experimentally validate these results. 😃 Additionally, we've discussed other intriguing facts, such as the overlap between different order multipactor zones and the intricate dependency of multipactor thresholds on both secondary electron yield crossover points. https://lnkd.in/g95wt8AK #Multipactor #AFOSR #satellitecommunications #PlasmaPhysics

📃Scientific paper: Gravitational Wave Symphony from Oscillating Spectator Scalar Fields Abstract: We investigate a generic source of stochastic gravitational wave background (SGWB) due to the parametric resonance of oscillating scalar fields in the early Universe. By systematically analyzing simple benchmark models using lattice simulation and considering a wide range of parameter space, we demonstrate that such a scenario can lead to detectable signals in GW detectors over a broad frequency range and potentially address the recent finding by NANOGrav. Furthermore, these models are found to naturally yield ultra-light dark matter candidates or dark radiation detectable by CMB observatories. ;Comment: 11 pages, 2 figures Continued on ES/IODE ➡️ https://etcse.fr/F5K ------- If you find this interesting, feel free to follow, comment and share.
