High Quality Content by WIKIPEDIA articles! Rafael Armenteros (1922-2004) was a Spanish particle physicist, who was one of the leading figures in CERN's various bubble chamber experiments. He is best known for the method he co-devised with J. Podolansky in 1953-1954. 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. 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.
