Drawing Particle Symbols and Feynman Diagrams with Office
  Particle symbols and Feynman diagrams often used in particle physics can be generated by a word document processor. Standard office packages have their built in symbols such as solid-line, dashed-line, arrows, etc. which are also used in particle physics. Three symbols corresponding to photon, gluon and fermion line are not present in the standard office packages. By importing these two symbols and using the built in symbols, tree-level Feynman diagrams can be easily generated in an office program.
