CAST Sets New Benchmarks in the Quest for Axions
CAST Sets New Benchmarks in the Quest for Axions Within the CERN Axion Solar Telescope (CAST) collaboration, scientists from the Center for Astroparticles and High-Energy Physics (CAPA) at the University of Zaragoza led the research that has achieved a significant milestone in the search for axion-like particles (ALPs). Published in Physical Review Letters, their latest

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

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

AMBER uncovers the universe’s mysteries
AMBER uncovers the universe’s mysteries The AMBER spectrometer. Credit: K Bernhard-Novotny/A Sargsyan Despite our extensive knowledge, the universe remains mysterious in many ways. To this day, questions prevail about the origin of the matter-antimatter asymmetry. The exact sources of antiprotons in our galaxy are largely unknown. Do they originate from cosmic ray collisions with the

ISOLDE’s New Beta-Decay Station Unlocks Advanced Decay-Spectroscopy Experiments with Laser-Polarised Unstable Nuclei
ISOLDE’s New Beta-Decay Station Unlocks Advanced Decay-Spectroscopy Experiments with Laser-Polarised Unstable Nuclei Exciting new opportunities for experiments with beta-decaying atomic nuclei have arisen at the ISOLDE facility with the recently developed new spectroscopy station called DeVITO [1]. The novelty of the setup lies in its integration with the VITO beamline for laser-polarisation of radioactive beams

Studying FIPs with FASER – recent news
Studying FIPs with FASER – recent news Feebly Interacting Particles (FIPs) exist within both the Standard Model (SM) and in theories that extend beyond it. The FASER experiment [1] is the first of two experiments approved for data taking in Run 3 aiming to study these elusive particles. Located 480 meters from the ATLAS interaction

Highlights from the Alpha Magnetic Spectrometer on the International Space Station
Highlights from the Alpha Magnetic Spectrometer on the International Space Station The Alpha Magnetic Spectrometer, AMS, is a high-energy particle detector performing unprecedented-precision measurements of cosmic rays of rigidity (momentum/charge) ranging from GV to 3 TV on the International Space Station (ISS). AMS has now reached 13 years of continuous operation, and it has collected

MoEDAL-MAPP Experiment’s Quest for Anomalously Charged Avatars of New Physics
MoEDAL-MAPP Experiment’s Quest for Anomalously Charged Avatars of New Physics Nature, as described by the Standard Model (SM), has decreed that stable or pseudo-stable subnuclear charged particles can only have an observable electrical charge of ±1e, where e is the charge of an electron and that there is no magnetic charge. Thus, searching for anomalously

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
