Rafael Armenteros

Rafael Armenteros (1922 – 5 March 2004) was a Spanish particle physicist, who was one of the leading figures in CERN's various bubble chamber experiments.^[1] Armenteros got his physics degree from Imperial College London in 1946,^[2] and began his scientific career at the University of Manchester. After working on cosmic rays with Blackett and Butler,^[3] and later with Leprince-Ringuet at École Polytechnique,^[4] he subsequently worked at CERN with Charles Peyrou.

Armenteros is best known for the method he co-devised with Jiří Podolský in 1953–1954.^[5] This technique is used in the analysis of the dynamics of two-body V decays and the relevant representation of data is known as an Armenteros-Podolansky plot.^[6] These plots were among the first few public results from the LHC experiments, since K⁰
_S and (anti-)lambda particles studied this way provide good examples for the demonstration of the performance of the tracking systems.^[7]
