Question: Which scientific collaboration was established under the leadership of Barry Banish an American experimental physicist?
Context: Luis Walter Alvarez (June 13, 1911 – September 1, 1988) was an American experimental physicist, inventor, and professor who was awarded the Nobel Prize in Physics in 1968.  The American Journal of Physics commented, "Luis Alvarez was one of the most brilliant and productive experimental physicists of the twentieth century." Duncan G. Steel (born 1951) is an American experimental physicist, researcher and professor in quantum optics in condensed matter physics.  He is the Robert J. Hiller Professor of Electrical Engineering, Professor of Physics, Professor of Biophysics, and Research Professor in the Institute of Gerontology at the University of Michigan.  Steel is also a Guggenheim Scholar and a Fellow of American Physical Society, the Optical Society of America, and the Institute of Electrical and Electronics Engineers.  He coedited the five-volume series on the Encyclopedia of Modern Optics. Robert Andrews Millikan (March 22, 1868 – December 19, 1953) was an American experimental physicist honored with the Nobel Prize for Physics in 1923 for the measurement of the elementary electronic charge and for his work on the photoelectric effect. LeRoy W. Apker (June 11, 1915 – July 5, 1970) was an American experimental physicist.  Along with his colleagues E. A. Taft and Jean Dickey, he studied the photoelectric emission of electrons from semiconductors and discovered the phenomenon of exciton-induced photoemission in potassium iodide.  In 1955, he received the Oliver E. Buckley Condensed Matter Prize of the American Physical Society for his work. Barry Clark Barish (born January 27, 1936) is an American experimental physicist.  He is a Linde Professor of Physics, emeritus at California Institute of Technology.  He is a leading expert on gravitational waves. The LIGO Scientific Collaboration (LSC) is a scientific collaboration of international physics institutes and research groups dedicated to the search for gravitational waves.  The LSC was established in 1997, under the leadership of Barry Barish.  Its mission is to ensure equal scientific opportunity for individual participants and institutions by organizing research, publications, and all other scientific activities, and it includes scientists from both LIGO Laboratory and collaborating institutions.  Barish appointed Rainer Weiss as the first spokesperson. Steven Cundiff is an American experimental physicist and the Harrison M. Randall collegiate professor of physics at the University of Michigan.  His research interests include the production and manipulation of ultrafast pulses, in particular for applications in studying light-matter interactions.  Cundiff is a Fellow of American Physical Society, the Optical Society of America, and the Institute of Electrical and Electronics Engineers.  He is the co-author (with Jun Ye) of the standard reference for frequency combs titled "Femtosecond Optical Frequency Comb: Principle, Operation and Applications". Robert Benjamin Leighton ( ; September 10, 1919 – March 9, 1997) was a prominent American experimental physicist who spent his professional career at the California Institute of Technology (Caltech).  His work over the years spanned solid state physics, cosmic ray physics, the beginnings of modern particle physics, solar physics, the planets, infrared astronomy, and millimeter- and submillimeter-wave astronomy.  In the latter four fields, his pioneering work opened up entirely new areas of research that subsequently developed into vigorous scientific communities. Scientific collaboration network is a social network where nodes are scientists and links are co-authorships as the latter is one of the most well documented forms of scientific collaboration.  It is an undirected, scale-free network where the degree distribution follows a power law with an exponential cutoff – most authors are sparsely connected while a few authors are intensively connected.  The network has an assortative nature – hubs tend to link to other hubs and low-degree nodes tend to link to low-degree nodes.  Assortativity is not structural, meaning that it is not a consequence of the degree distribution, but it is generated by some process that governs the network’s evolution. Bernard F. Schutz (born August 11, 1946, in Paterson, New Jersey) is an American physicist.  His research is on Einstein's theory of general relativity, more concretely on the physics of gravitational waves.  He is one of the directors and head of the astrophysics group at the Max Planck Institute for Gravitational Physics in Potsdam, Germany.  He is principal investigator in charge of data analysis for the GEO600 collaboration (which, in turn, is part of the LIGO Scientific Collaboration, the largest concerted effort to directly detect gravitational waves).  Schutz is also a member of the science team coordinating the planning and development for the space-borne gravitational wave detector LISA (Laser Interferometer Space Antenna), and he was instrumental in the foundation of the electronic, open access review journal "Living Reviews in Relativity".
