The Cartagena José Manuel Alarcon Soriano is the author of the dissertation has been awarded by the Nuclear Physics Division of the European Physical Society.
The thesis, conducted at the University of Murcia under the direction of Professor José Antonio Oller, delves into one of the four fundamental forces of nature by holding together protons and neutrons in the nucleus of the atom.
One of the most important practical consequence of this work is the removal of so-called "sigma term" concept that refers to "a fundamental amount in the theory of strong interactions or QCD, which hold protons and neutrons, generically called nucleons within the atomic nucleus, "he explains the author.
This amount, added Alarcón, is essential to understand the structure of the nucleon mass and content, which in turn is composed of quarks.
The calculation of sigma is essential for "the detection of dark matter, the study of nuclear thermodynamics, work load-parity violation, trying to explain the asymmetry between matter and antimatter in the universe, as well as studies on anthropic the origin of life, "explains the young researcher.
At the theoretical level, the results consolidate the foundations on which to develop methods for studying nuclear reactions much more complex from the fundamental principles of the standard model, a theory that describes elementary particles and their interactions, a field in currently working José Manuel Alarcon in Bonn (Germany).
After defending his thesis at the University of Murcia in June 2012, Alarcon moved to the Institute of Nuclear Physics of Johannes Gutenberg University in Mainz, Germany.
In September 2014, he began a new postdoctoral position at the Helmholtz Institute for Radiation and Nuclear Physics in Bonn, where he joined the research group led by Professor Ulf Meißner.
The award will be presented at the beginning of September at the 3rd European Conference on Nuclear Physics, held in Groningen (Netherlands).
