Enrico Chesta, Véronique Ferlet-Cavrois and Markus Brugger highlight seven ways CERN and ESA are working together to further fundamental exploration and innovation in space technologies. Sky map The ...

Mark Thomson is professor of experimental particle physics at the University of Cambridge and was executive chair of the UK’s Science and Technology Facilities Council (STFC) until his confirmation as ...

Patrick Koppenburg and Marco Pappagallo survey the 23 exotic hadrons discovered at the LHC so far. Twenty-three exotic states Five pentaquarks and 18 tetraquarks have been discovered so far at the LHC ...

Alexander Lenz argues that the charm quark is an experimental and theoretical enigma that has the potential to shed light on the matter–antimatter asymmetry in the universe. Threading the needle The ...

Early-career researchers tell the Courier what they think is the key strategic issue for the future of high-energy physics. Accelerating into the future Seventy years after construction began on ...

The Courier matched photos from CERN’s first 25 years to current experts and asked them to reflect on how much has changed across 70 years of science. The past seven decades have seen remarkable ...

From its pristine vantage point on the International Space Station, the Calorimetric Electron Telescope, CALET, has uncovered anomalies in the spectra of protons and electrons below the cosmic-ray ...

André de Gouvêa explains why neutrino masses imply the existence of new fundamental fields. Misfits Massive neutrinos are not part of the Standard Model. Credit: Symmetry After all these years, ...

After 25 years of steady progress, recent advances in theory and computing are enabling researchers to connect an approach to quantum gravity called asymptotic safety to the Standard Model. Frank ...

When lead ions collide head-on at the LHC they deposit most of their kinetic energy in the collision zone, forming new matter at extremely high temperatures and energy densities. The hot and dense ...

Significant technology development is required to establish the feasibility of a muon collider. Mastering it, says Mark Palmer, offers an alternative path to the next energy frontier. The physics ...

Detecting and exploring a stochastic background of gravitational waves predicted to pervade the universe potentially opens a window on the extreme physics of the very early universe. Azadeh Maleknejad ...
