A word from the EP Department Head – Spring 2026
A word from the EP Department Head – Spring 2026 Dear Colleagues, It is my pleasure to share the first 2026 edition of the EP newsletter with you, in my new role as EP Department Head. CERN’s new management took office in January, with a revised structure of Sectors and Departments. In EP, we reorganised

New Staff Members and Fellows
New Staff Members and Fellows Maximilian Babeluk Hi, I’m Max. I recently joined the ALICE ITS3 team, where I work on sensor testing, functional verification, and in the future also chip design – particularly on MOSAIX. My main activities include testing and yield assessment across multiple integration levels (wafer probing to system tests), including data

From particle flow to learned reconstruction at CMS
From particle flow to learned reconstruction at CMS An interactive version of the above event display can be found on this page. For more than a decade, particle-flow reconstruction has been at the core of CMS event interpretation. It was instrumental in the discovery of the Higgs boson and remains foundational for virtually every analysis

First HGCAL absorber structure delivered to CERN for assembly
First HGCAL absorber structure delivered to CERN for assembly After an eight-week journey, the first HGCAL absorber structure (CE-H1) was delivered to CERN and is ready to be assembled, just 100 metres above the location where the detector will eventually be installed. Seventeen enormous boxes were delivered at the CMS experimental site at the beginning

Dark Showers at the LHC: from benchmarks to Run-3 readiness
Dark Showers at the LHC: from benchmarks to Run-3 readiness The search for new physics at the LHC increasingly pushes beyond traditional signatures. Among the most intriguing possibilities are dark showers—complex cascades of particles emerging from dark-sector dynamics, capable of producing rich, unconventional final states. These scenarios naturally arise in models where dark matter interacts

Triple Higgs Frontiers: Mapping the Higgs self-couplings at the 2025 HHH workshop
Triple Higgs Frontiers: Mapping the Higgs self-couplings at the 2025 HHH workshop More than a decade after the discovery of the Higgs boson, attention is shifting from finding the Higgs to mapping its self-interactions. These self-couplings determine the shape of the Higgs potential, and with it the stability of our vacuum and the early Universe.

Light ions at the LHC: first results from oxygen–oxygen and neon–neon collisions
Light ions at the LHC: first results from oxygen–oxygen and neon–neon collisions This summer, the Large Hadron Collider (LHC) delivered its first-ever collisions between light ions, opening a new chapter in the study of nuclear structure and the quark–gluon plasma (QGP) – the extreme state of matter that existed in the first instants of the

CMS explores light-ion collisions: suppression, scaling, and collectivity
CMS explores light-ion collisions: suppression, scaling, and collectivity The CMS experiment has reported first results from the LHC’s dedicated oxygen–oxygen (O–O) and neon–neon (Ne–Ne) collision run, offering an unprecedented look at quark–gluon plasma (QGP) formation in light-ion systems. These studies address long-standing questions about the minimal conditions required for QGP droplets to form and how

OLC-R / OLC-1 refurbishment in a Nutshell
OLC-R / OLC-1 refurbishment in a Nutshell For Phase-2, CMS DAQ will undergo a major increase of its capacities to match HL-LHC performance and the related CMS physics program. Compared to the present situation (Run3), the post-trigger data throughput will increase from 2 Tb/s today to 50 Tb/s for Run4 and the processing power needed
