I'm glad to see there are more data to be found in the run 2 datasets! It will also be interesting to see what comes out of the HL-LHC project. It has already been in the making for years.

I did my 2.5 year fellowship on it in 2017 to 2019, but I'm not very familiar with the interactions they're studying here. W and Z were discovered at CERN in the early 80s though using the LEP accelerator, the LHC's predecessor.

🚀 #CERN just dropped a novel-length snooze-fest about a collider that may or may not exist. Apparently, smashing particles isn't enough—they now need a *circular* ride. 🎢 Because nothing says "cutting-edge science" like a report on something imaginary. 🤡

CERNCERN releases report on the feasibility of a possible Future Circular ColliderAfter several years of intense work, CERN and international partners have completed a study to assess the feasibility of a possible Future Circular Collider (FCC). Reflecting the expertise of over a thousand physicists and engineers across the globe, the report presents an overview of the different aspects related to the potential implementation of such a project. The FCC is a proposed particle collider with a circumference of about 91 km that could succeed CERN’s current flagship instrument – the 27-km Large Hadron Collider (LHC) – in the 2040s. Its scientific motivation stems from the discovery of the Higgs boson in 2012, along with other crucial outstanding questions in fundamental physics. The Higgs boson is the simplest yet most perplexing particle discovered so far, with properties that have far-reaching implications for our existence. It is related to the mechanism that enabled elementary particles such as electrons to gain mass a fraction of a nanosecond after the Big Bang, allowing atoms and thus structures to form. It may also be connected to the fate of the Universe and could potentially shed light on the many unsolved mysteries of modern physics. As described in Feasibility Study Report, the FCC research programme outlines two possible stages: an electron–positron collider serving as a Higgs, electroweak and top-quark factory running at different centre-of-mass energies, followed at a later stage by a proton–proton collider operating at an unprecedented collision energy of around 100 TeV. The complementary physics programmes of each stage match the highest priorities set out in the 2020 update of the European Strategy for Particle Physics. The report covers wide-ranging aspects related to the potential implementation of such a project. These include physics objectives, geology, civil engineering, technical infrastructure, territorial and environmental dimensions, R&D needs for the accelerators and detectors, socioeconomic benefits, and cost. The estimated cost of construction of the FCC electron–positron stage, including the tunnel and all the infrastructure, is 15 billion Swiss francs. This investment, which would be distributed over a period of about 12 years starting from the early 2030s, includes the civil engineering, technical infrastructure, electron and positron accelerators and four detectors for operation. As was the case for the construction of the LHC, the majority of the funding would come from CERN’s current annual budget. CERN has made a commitment that any new project at the Laboratory would be an exemplar of a sustainable research infrastructure, integrating ecodesign principles into every phase of the project, from design to construction, operations and dismantling. The report details the concepts and paths to keep the FCC’s environmental footprint low while boosting new technologies to benefit society and developing territorial synergies such as energy reuse. A major component of the FCC Feasibility Study has been the layout and placement of the collider ring and related infrastructure, which have been diligently studied to maximise the scientific benefit while taking into account territorial compatibility, environmental and construction constraints and cost. No fewer than 100 scenarios were developed and analysed before settling on the preferred option: a ring circumference of 90.7 km at an average depth of 200 m, with eight surface sites and four experiments. Throughout the Feasibility Study process, CERN has been accompanied by its two Host States, France and Switzerland, working with entities at the local, regional and national levels. Engagement processes with the public are being prepared in line with the Host States’ respective frameworks to ensure a constructive dialogue with territorial stakeholders. The report, which does not imply any commitments by the CERN Member and Associate Member States to build the FCC, will be reviewed by various independent expert bodies before being examined by the CERN Council at a dedicated meeting in November 2025. The Council may take a decision on whether or not to proceed with the FCC project around 2028. Particle colliders play a unique role in physics exploration. They also enable the development of unprecedented technologies in many fields of relevance for society, ranging from superconducting materials for medical applications, fusion energy research and electricity transmission to advanced accelerators and detectors for medical and many other applications. The FCC Feasibility Study was launched following the recommendations of the 2020 update of the European Strategy for Particle Physics and will serve as input for the ongoing update of the Strategy, along with studies of alternative projects proposed by the scientific community.

Universität Freiburg

Der „Breakthrough Prize in Fundamental Physics“ 2025 geht an vier CERN-Experimente – mit maßgeblicher Beteiligung der Universität Freiburg.

Die Teilchenphysik-Experimente ALICE, ATLAS, CMS und LHCb am CERN wurden für ihre Beiträge zur Entdeckung des Higgs-Bosons, zur Erforschung neuartiger Teilchen und zur Untersuchung der Materie-Antimaterie-Asymmetrie mit dem renommierten „Breakthrough Prize in Fundamental Physics“ ausgezeichnet.

Am ATLAS-Experiment waren und sind die Teams von Prof. Dr. Karl Jakobs, Prof. Dr. Gregor Herten, Prof. Dr. Markus Schumacher sowie seit Januar 2025 auch von Jun.-Prof. Dr. Brian Moser beteiligt. Ihre Arbeiten umfassten u. a. Aufbau, Betrieb und Analyse des Experiments sowie zentrale Beiträge zum Nachweis des Zerfalls des Higgs-Bosons in Quarks und geladene Leptonen. Jakobs war von 2017 bis 2021 Sprecher der internationalen ATLAS-Kollaboration.

Am LHCb-Experiment, das neue Einblicke in die Asymmetrie von Materie und Antimaterie sowie in seltenste Teilchenzerfälle ermöglicht, ist seit Juli 2024 eine neue Arbeitsgruppe unter Leitung von Prof. Dr. Marco Gersabeck am Physikalischen Institut beteiligt.

Darüber hinaus sind Freiburger Gruppen an der Weiterentwicklung der Experimente für die Hochluminositätsphase des LHC beteiligt. Für ATLAS und LHCb entstehen in Freiburg hochauflösende Silizium-Spurdetektoren, die ab 2030 zum Einsatz kommen sollen.

Vermisstes #Elementarteilchen nach 50 Jahren am #Cern entdeckt

In Daten des großen #Teilchenbeschleunigers am #Cern ist ein neues #Hadron entdeckt worden. Eigentlich hat man #Higgs-Bosonen gesucht.

Ein #Forschungsteam am #Cern hat in Daten, die von 2016 bis 2018 gesammelt wurden, das letzte noch fehlende #Hadron des #Quarkoniums gefunden. Das sind die gebundenen Zustände eines #Quarks mit seinem #Antiteilchen.
