Observation of deuteron and antideuteron formation from resonance-decay #nucleons / „So entstehen leichte Atomkerne“: https://www.nature.com/articles/s41586-025-09775-5 / https://www.weltderphysik.de/gebiet/teilchen/experimente/teilchenbeschleuniger/cern-lhc/alice-raetsel-der-teilchenphysik-geloest/ -> Decades-old mystery in particle physics solved: https://www.tum.de/en/news-and-events/all-news/press-releases/details/decades-old-mystery-in-particle-physics-solved

Atomic nuclei are made up of #nucleons-either #protons or #neutrons -
Binding energy per nucleon reaches a maximum for chemical element Iron
Every atom in our bodies but #hydrogen and heavier than iron ones was formed by nuclear fusion in core of massive stars many time ago in burning heat Hydrogen was formed after #BigBang in silent cold
As Iron is produced,stars get older
Probably Iron in your red blood cells traveled from dying star core
Our origins are fabulous,our reality is disappointing

It may be hard to imagine that the debris of violent heavy #ion collisions—which dissolve the boundaries of #protons and #neutrons and produce thousands of new particles—can be used to gain detailed insight into the properties of #nucleons
