1QCD vacuum — The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non perturbative vacuum state, characterized by many non vanishing condensates such as the gluon condensate or the quark condensate. These condensates… …
2History of string theory — 1943 1958: S Matrix String theory is an outgrowth of a research program begun by Werner Heisenberg in 1943, picked up and advocated by many prominent theorists starting in the late 1950s and throughout the 1960s, which was discarded and… …
3Vector meson — In high energy physics, a vector meson is a meson with total spin 1 and odd parity (usually noted as JP =1−). Compare to a pseudovector meson, which has a total spin 1 and even parity.Vector mesons have been seen in experiments since the 1960s,… …
4Bunji Sakita — (1930–August 31, 2002) was a Japanese American theoretical physicist who was an important figure in the world of physics. He made important contributions in quantum field theory, superstring theory and discovered supersymmetry in 1971. He was a… …
5Totalitarian principle — In quantum mechanics, Gell Mann s Totalitarian Principle states: Everything which is not forbidden, is compulsory. Physicist Murray Gell Mann borrowed this expression from T.H. White s The Once and Future King to describe the state of particle… …
6Automatic calculation of particle interaction or decay — The automatic calculation of particle interaction or decay is part of the computational particle physics branch. It refers to computing tools that help calculating the complex particle interactions as studied in high energy physics, astroparticle …
