This collection features 11 visually engaging posters tracing CERN’s evolution — from its pioneering discoveries and groundbreaking technologies to the vision of the Future Circular Collider (FCC), an international endeavour designed to extend our quest for knowledge into the post-LHC era. Together, these posters highlight CERN’s enduring role at the forefront of global scientific exploration.Cette collection comprend 11 posters visuellement captivantes retraçant l’évolution du CERN — de ses découvertes pionnières et de ses technologies novatrices jusqu’à la vision du projet "Future Circular Collider" (FCC). Cette initiative internationale est conçue pour prolonger notre quête de connaissance dans l’ère post-LHC. Cet ensemble de posters mettent en lumière le rôle durable du CERN à l’avant-garde de l’exploration scientifique mondiale.

The scientific purpose of this experiment, conducted in August 2025, was to identify fracture limits of pre-cracked tungsten and titanium materials, validate simulations predicting pulsed-beam induced damage in ceramic nanofiber samples under atmospheric and vacuum conditions, and understand failure mechanisms, limitations, and flow behavior of various material specimens. The experimental set-up comprised of multiple arrays of specimens, each exposed to different beam intensities. A total of 72 samples were tested including conventional materials (graphite, and titanium alloys) and novel materials (Toughened Fine-Grained Recrystallized (TFGR) Tungsten, electrospun nanofiber materials (ZrO2, W), SiC, Pure W, and high-entropy alloys) pertinent to accelerator beam windows and secondary particle production targets.

Search for the charmless baryonic decay B+→Λ¯pp¯p is performed using proton-proton collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 5.4fb−1. The branching fraction is measured to be B(B+→Λ¯pp¯p)=(2.08±0.34±0.10±0.26)×10−7, where the first uncertainty is statistical, the second is systematic, and the third arises from the normalization channel. The CP asymmetry is measured to be ACP=(5.4±15.6±2.4)%, where the uncertainties are statistical and systematic. The background-subtracted invariant mass distributions of baryon-antibaryon pairs exhibit pronounced enhancements at both kinematic thresholds.

CERN technologies: from fundamental research to our everyday lives. Since 1954, the world-class research performed at CERN helps uncover what the universe is made of and how it works: here, scientists from all over the world study elementary particles – invisible to the eye – through complex and often gigantic instruments.

HRMT-60 - RaDIATE Material Studies Nicht eingeplant 3h CERN Poster Cocktail - Poster session Beschreibung HRMT-60 experiment was performed at the CERN-HiRadMat facility in October 2022 to understand thermal shock response of conventional materials and novel materials to support the design and operation of future multi-MW accelerator beam windows and secondary particle-production targets. This experiment, organized within the framework of the RaDIATE collaboration, builds on the previous HRMT-43 (BeGrid2) experiment, where a variety of materials in both non-irradiated and previously proton-irradiated conditions were tested. The primary goal was to understand the failure mechanisms, limits and flow behavior of the various material specimens, as well as compare and contrast the thermal shock response of previously irradiated materials to their non-irradiated counterparts. A total of 120 samples were tested at different beam conditions. This poster will present the preliminary results of several materials tested during this experiments.
