Question: In particle physics, the Yukawa interaction was named after which Japanese theoretical physicist?
Context: Jeffrey Robert Forshaw (born 1968) is a British particle physicist with a special interest in quantum chromodynamics (QCD): the study of the behaviour of subatomic particles, using data from the HERA particle accelerator, Tevatron particle accelerator and the Large Hadron Collider (LHC) at CERN.  Since 2004 he has been professor of particle physics in the School of Physics and Astronomy at the University of Manchester.  He is the co-author of 5 books, most notably the worldwide bestselling popular science books "Why Does E=mc²? ", "The Quantum Universe" and "Universal: A guide to the cosmos", co-written with physicist Brian Cox.  He has also written over 100 peer reviewed papers published in scientific journals and speaks at international science festivals for children and adults.  He frequently acts as science consultant to the BBC and other media and is a columnist for "The Observer".  Forshaw is a recipient of the Maxwell Medal and Prize for his outstanding contribution to particle physics, and the Kelvin Prize from the Institute of Physics for his exceptional contribution to the public understanding of physics. 湯川 秀樹 ("Yukawa Hideki" , 23 January 1907 – 8 September 1981 ) , was a Japanese theoretical physicist and the first Japanese Nobel laureate. Julius Ashkin (August 23, 1920 – June 4, 1982) was a leader in experimental and theoretical physics known for furthering the evolution of particle physics from nuclear physics.  As a theoretical physicist he made contributions in the fields of statistical mechanics, solid state physics, nuclear physics, and elementary particle physics.  As an experimental physicist his main contributions concerned the passage of certain particles (pi-mesons, or pions) through solid matter and their subsequent decay.  He was recognized for the quality of his research and teaching. Palash Baran Pal (Bengali: পলাশ বরন পাল "Palāś Baran Pāl", born : 1955) is an Indian theoretical physicist, a senior professor at Saha Institute of Nuclear Physics, Kolkata, a writer, a linguist and a poet.  His main area of research is Particle Physics.  His works in the area of neutrino physics and relativistic treatment of particle properties in matter are well recognized in the particle physics community.  Apart from his scientific contributions, he has authored well known text books in physics as well as several popular science literature in Bengali to popularize science. In particle physics, Yukawa's interaction or Yukawa coupling, named after Hideki Yukawa, is an interaction between a scalar field ϕ and a Dirac field ψ of the type Computational particle physics refers to the methods and computing tools developed in and used by particle physics research.  Like computational chemistry or computational biology, it is, for particle physics both a specific branch and an interdisciplinary field relying on computer science, theoretical and experimental particle physics and mathematics. Yoshio Koide (小出 義夫 , Koide Yoshio , born May 16, 1942 in Kanazawa, Ishikawa) is a Japanese theoretical physicist specializing in particle physics.  Koide is famous for his eponymous Koide formula, which some physicists think has great importance while other physicists contend that the formula is merely a numerical coincidence. Juansher Levan Chkareuli (Georgian: ჯუანშერ ჩქარეული ; born 1940, Tbilisi) is a Georgian theoretical physicist working in particle physics, Professor at Institute of Theoretical Physics of Ilia State University in Tbilisi and Head of Particle Physics Department at Andronikashvili Institute of Physics of Tbilisi State University. Sam Bard Treiman (May 27, 1925 – November 30, 1999) was an American theoretical physicist who produced research in the fields of cosmic rays, quantum physics, plasma physics and gravity physics.  He made contributions to the understanding of the weak interaction and he and his students are credited with developing the so-called standard model of elementary particle physics.  He was a professor of physics at Princeton University, a member of the National Academy of Sciences and member of the JASON Defense Advisory Group.  He was a student of Enrico Fermi and John Alexander Simpson Jr.  Treiman published articles on quantum mechanics, plasmas, gravity theory, condensed matter and the history of physics. Particle physics phenomenology is the part of theoretical particle physics that deals with the application of theoretical physics to high-energy experiments.  Phenomenology forms a bridge between the mathematical models of theoretical physics (such as quantum field theories and theories of the structure of space-time) and experimental particle physics, by making quantitative predictions based upon the theoretical models.  Phenomenology is related to the philosophical notion in that these predictions describe anticipated behaviors for phenomena in reality.
