A proton (far left) from the Super Proton Synchrotron (SPS) accelerator at CERN impinges on carbon nuclei (small gray spheres). This produces a shower of various elementary particles, including a ...

Recent advances in laser technology have enabled the exploration of previously inaccessible regimes where electrons interact with ultra-intense electromagnetic fields. These interactions drive ...

When electrons collide with positrons, their antimatter counterparts, unstable pairs can form in which both types of particle orbit around each other. Named 'positronium', physicists have now produced ...

New research reveals the characteristics of positronium formation within football-shaped nanoparticles, C60, for the first time. At specific positron impact energies, the study shows that positronium ...

Quantum field theories are powerful tools for particle physics and condensed matter physics but are rarely used in plasma physics. However, in warm-dense regimes, where matter is partially ionized and ...
