CLUE: A Scalable Clustering Algorithm for the Data Challenges of Tomorrow

The foreseen increase in luminosity and pileup at the High-Luminosity Large Hadron Collider (HL-LHC) [1] will challenge both the detector hardware and the reconstruction software. With higher pile-up, calorimeter energy reconstruction depends even…

AMS-02: A New Chapter in Orbit to Probe the Nature of Cosmic Rays

Since its launch aboard the International Space Station (ISS) in May 2011, the Alpha Magnetic Spectrometer (AMS-02) has recorded more than 250 billion cosmic-ray events, offering precision measurements of the composition and energy spectra of…

Heavy isotopes production via electromagnetic interactions at the LHC

The ALICE experiment at LHC studies ultra-relativistic heavy-ion collisions to characterize the Quark-Gluon Plasma (QGP) — a state of matter where quarks and gluons are deconfined. This state existed briefly in the early Universe, just a few…

Anomaly at the Threshold: A Closer Look at tt̄ Events in CMS

Some of the most intriguing developments in physics begin not with a discovery, but with an anomaly, subtle, persistent, and difficult to ignore. In 2019, CMS reported a mild excess of around three standard deviations in a search for heavy…

ATLAS Approaching a Breakthrough in Diboson Polarization with Run-3 Data

The study of the polarisation of vector boson scattering (VBS) processes provides a unique test of the Higgs mechanism’s role in taming high-energy electroweak interactions, making it indispensable for fundamental physics for the last decades. As…

TELMAX: A New Era of Flexibility at CERN's Antimatter Factory

PAX UHV test chamber equipped with linear target manipulator and Ti x-ray window. The ADR cryostat containing the TES detector can be seen facing the chamber in its measurement position. X-rays from the antiprotonic atom cascade traverse the Ti…
