Extended Scalar Sectors are considered from all angles at CERN
Extended Scalar Sectors are considered from all angles at CERN It has been more than ten years since the discovery of the first scalar particle at the electroweak scale. This particle was discovered at the LHC in 2012, and it was quickly found to be a scalar that is compatible with the Higgs boson predicted

NA62 Observes Ultra-Rare Kaon Decay to Pion and Neutrinos
NA62 Observes Ultra-Rare Kaon Decay to Pion and Neutrinos The NA62 experiment at the CERN north area was built to investigate the ultra-rare K+ → π+νν̄ decay. Measurement of this decay, a golden mode for kaon physics, is considered a key flavour physics objective because it provides both a strong test of the Standard Model

Perturbed angular correlations at ISOLDE
Perturbed angular correlations at ISOLDE Solid state physics and biophysics research has been conducted at ISOLDE-CERN for almost 50 years [JOH2017]. Our role in supporting experimental equipment and manpower has enabled the development of on-site laboratories. This has several advantages, from nuclear physics studies to the applications for society. Being part of the in-house group

Development of Radiation Tolerant Silicon Detectors for the LHC and HL-LHC
Development of Radiation Tolerant Silicon Detectors for the LHC and HL-LHC Introduction The potential of semiconductor-based detectors for particle detection in nuclear and high-energy physics (HEP) has been identified as early as 1960. However, it took two more decades of development to transform these detectors into reliable, fully operational systems. Silicon-based tracking detectors made their

LHC Run 3: A Marathon of Progress and Perseverance
LHC Run 3: A Marathon of Progress and Perseverance Earlier this month, the Large Hadron Collider reached an unprecedented milestone of 100 inverse femtobarns – equivalent to 10 million billion collisions – delivered to the ATLAS and CMS experiments in 2024, with 28 days of proton-proton collisions remaining. This marks a historic first in a

ATLAS Operations: Progress and Highlights from 2023/2024
ATLAS Operations: Progress and Highlights from 2023/2024 Great progress has been made in the ATLAS operation since the last EP news article. There we presented the fantastic Phase-I upgrades of the ATLAS detector installed during LS2, described the steps towards their commissioning, and summarized the experience of the first data-taking year of Run 3. What

Breakthrough in the cooling technologies of a single antiproton/proton at the BASE experiment
Breakthrough in the cooling technologies of a single antiproton/proton at the BASE experiment The Baryon Antibaryon Symmetry Experiment (BASE) is recognized for performing the most precise measurements of the fundamental properties of antiprotons and protons, such as the 16 p.p.t. precision measurement of the antiproton-to-proton charge-to-mass ratio [1], the 1.5 p.p.b. precision measurement of the

Characterization, modelling and radiation hardening of silicon-detectors for future experiments.
Characterization, modelling and radiation hardening of silicon-detectors for future experiments. The Strategic R&D Programme on Technologies for Future Experiments of the EP Department (EP R&D) develops the detector technologies needed for the next generation of High Energy Physics experiments and recently concluded phase I (2020-2023) of its ambitious work plan with a close-out report [1].

A word from the EP Deputy Department Head – September 2024
A word from the EP Deputy Department Head – September 2024 Dear colleagues, As I write in mid-September, the days are getting shorter and colder, and we are in the midst of marking the 70th birthday of CERN, with the community party on 17th September, and the official celebrations on 1st October. It is an

DESI-Y1 and the Mystery of the Neutrino Mass
DESI-Y1 and the Mystery of the Neutrino Mass In April 2024, the Dark Energy Spectroscopic Instrument (DESI) collaboration released their first cosmological results [1]. These results made the news primarily because they showed some hints of dynamical dark energy (see the article in the same issue of the EP newsletter). However, they also had key
