Martin Breidenbach (born 1943) is an American professor of particle physics and astrophysics, emeritus, at Stanford University.
His research interests have included e+e- colliding beam physics, detector optimization, and electromagnetic calorimeters.
At SLAC he also became involved in Burton Richter's experiments on the SPEAR storage ring, and new charmonium states.
[5] Starting in 1980 Breidenbach was involved in the construction of the Stanford Linear Collider (SLC) control system and design of the SLD detector.
In 1984 he became co-spokesman for the SLD with Charles Baltay, making precise determinations of the parameters of the electroweak interaction.
