FCC Week 2026: from scientific ambition to an integrated design
FCC Week 2026: from scientific ambition to an integrated design by Panos Charitos (CERN) This year’s annual conference brought together 656 participants in Helsinki to examine how the Future Circular Collider study can move from feasibility demonstration towards a coherent reference design. With its primary focus on FCC-ee, the meeting presented a project in which

ANUBIS: from prototype to Letter of Intent
The proANUBIS demonstrator has completed data taking in the ATLAS cavern, showing that its detector technology delivers the efficiency and timing precision required to search for long-lived particles. These results strengthen the case for the full ANUBIS experiment, which would extend ATLAS’s reach into a largely unexplored region of new physics.

From beam dumps to missing energy: the SPS search for hidden particles
For more than four decades, CERN’s Super Proton Synchrotron has served as a testing ground for new ways to search for particles that interact only feebly with ordinary matter. In a recent lecture, NA64 co-spokesperson Paolo Crivelli traced the evolution of this programme – from the first beam-dump experiments to missing-energy and missing-momentum searches, precision…

Designing for the unusual: LLP2026 and the lifetime frontier
LLP2026 brought around 80 theorists and experimentalists to Cambridge at a moment of transition for the lifetime frontier. From new searches using Run 3 LHC data and unconventional signatures to prototype detectors and new experimental concepts, the workshop showed how long-recognised blind spots are being turned into concrete experimental capabilities.

FASER opens new windows on dark sectors and TeV neutrino physics
FASER opens new windows on dark sectors and TeV neutrino physics The FASER experiment has presented a series of new results that highlight the growing breadth of its physics programme at the LHC. These include a search for dark photons with the main FASER detector, a first search for neutrino-induced charm production with FASERν, and

Looking in all directions for long-lived particles at the LHC
Looking in all directions for long-lived particles at the LHC In 1984, Alvaro de Rujula pointed out that the proton-proton collisions at the LHC would produce large fluxes of very high energy neutrinos in the forward direction [1]. In 2023, almost 40 years later, the FASER and SND experiments ushered in the era of collider

SND@LHC gears up for data taking
SND@LHC gears up for data taking The last fifteen months have been a full-fledged race against the clock for the SND@LHC Collaboration. The experiment was approved by the Research Board in March 2021 with the goal of taking data in Run 3 of the LHC. The Collaboration has had to construct and test the sub-detectors

LLP11: The eleventh workshop of the Long-Lived Particle Community
LLP11: The eleventh workshop of the Long-Lived Particle Community Amidst the excitement of preparations for the impending Run 3 of the Large Hadron Collider (LHC), as well as prominent developments of key projects around the globe, the eleventh workshop of the Long-Lived Particle (LLP) Community initiative (LLP11) was held virtually from 30 May to 3

Exploring the Lifetime Frontier at the LHC and Beyond
Exploring the Lifetime Frontier at the LHC and Beyond By any reasonable measure, the first ten years of the LHC have been an unmitigated success. But are we exploring everywhere in our data? The overwhelming majority of the searches for particles beyond the Standard Model (BSM) conducted at ATLAS and CMS, for example, assume that

FASER joins the exploration for new physics
FASER joins the exploration for new physics On March 5th the CERN Research Board approved the ForwArd Search ExpeRiment (FASER), for installation at the LHC during Long Shutdown 2. FASER is an experiment designed to broaden the search for new physics at the LHC, by looking for light, weakly- interacting new particles that could be
