Michael Dine (born 12 August 1953) is an American theoretical physicist, specializing in elementary particle physics, supersymmetry, string theory, and physics beyond the Standard Model.

Education and career Dine received in 1974 a bachelor's degree from Johns Hopkins University and in 1978 a Ph.D. under Thomas Appelquist from Yale University with thesis Interactions of Heavy Quarks in Quantum Chromodynamics. He did research at SLAC and was for a number of years at the Institute for Advanced StudyMichael Dine, Institute for Advanced Study and the Henry Semat Professor at City College of New York. He is currently a professor at Santa Cruz Institute for Particle Physics (SCIPP) of the University of California, Santa Cruz.

Dine was a Guggenheim Fellow for the academic year 2006–2007 and Sloan Fellow in 1986. He is a fellow of American Physical Society and in 2010 he was elected a fellow of the American Academy of Arts and Sciences. He is a recipient of the 2018 Sakurai Prize. He was elected a member of the National Academy of Sciences in April 2019.

Research Dine works on the "phenomenology" (i.e. experimentally testable models for low energy) of supersymmetric extensions of the Standard Model and of superstring theory. In particular, he does research on supersymmetry breaking. Dine investigated in the 1980s modifications of quantum chromodynamics with dynamical supersymmetry breaking (DSB), partly with Ian Affleck and Nathan Seiberg.Ian Affleck, Dine, Nathan Seiberg Dynamical supersymmetry breaking in supersymmetric QCD, Nucl. Phys. B, vol. 241, 1984, pp. 493–534 ; the same authors, Dynamical supersymmetry breaking in chiral theories, Phys.Letters B, vol. 137, 1984, pp. 187–192 With Willy Fischler and Mark Srednicki, Dine published in 1981 a theory of supersymmetric technicolor, using gauge bosons and their superpartners, that provided a model of gauge-mediated supersymmetry breaking.Dine, Fischler, Srednicki Nuclear Physics B, vol. 189, 1981, p. 575, Dine, Fischler Physics Letters B, vol. 110, 1982, p. 227, Dine, Srednicki Nucl.Phys. B, vol. 202, 1982, p. 238. Independently, similar research was done by Savas Dimopoulos, Stuart Raby, Nucl. Phys., vol.192, 1981, p. 353, and by Edward Witten, Dynamical Breaking of Supersymmetry, Nucl. Phys. B, vol. 188, 1981, p. 513. See Giudice, Rattazzi: Theories with gauge mediated supersymmetry breaking, Physics Reports vol. 322, 1999, Dine with Affleck and Seiberg developed a general theory of dynamical supersymmetry breaking in four-dimensional spacetimeAffleck, Dine, Seiberg: Dynamical supersymmetry breaking in four dimensions and its phenomenological implications, Nucl. Phys. B, vol. 256, 1985, p. 557, and with Ann Nelson, Yuri Shirman, and Yosef Nir developed new models of gauge-mediated dynamical supersymmetry breaking.Dine, Nelson, Nir, Shirman: New tools for low energy dynamic supersymmetry breaking, Physical Review D, vol. 53, 1996, p. 2658,

With Fischler and Srednicki he developed an "Invisible Axion" model known as the DFSZ (Dine–Fischler–Srednicki–Zhitnisky) model.Dine, Willy Fischler, Mark Srednicki A simple solution of the strong CP Problem with a harmless axion, Physics Letters B, vol. 104, 1981, pp. 199–202 . At approximately the same time, similar research was independently done by Mikhail Shifman and colleagues. Later Dine with Fischler also elaborated this theory and its cosmological implications (the axion is a candidate for a dark matter particle). To explain the matter/antimatter imbalance in the universe, Dine and Ian Affeck proposed the Affleck–Dine mechanism.Dine, Affleck, Nuclear Physics B, vol. 249, 1985, p. 361. See Dine, Kusenko The origin of the matter-antimatter asymmetry, Rev. Mod. Phys., vol. 76, 2004. . The Affleck–Dine mechanism might provide a candidate for a dark matter particle, namely a particular type of Q-ball.

Dine investigated with Ryan Rohm, Nathan Seiberg and Edward Witten gluino condensation in string theory,Dine, Rohm, Seiberg, Witten Gluino condensation in superstring models, Physics Letters B, vol. 156, 1985, pp. 55–60 with Witten and Seiberg the implications of Fayet–Iliopoulos D-terms for vacuum destabilization,Dine, Seiberg, Witten Fayet-Iliopoulos Terms in String Theory, Nucl. Phys. B, vol. 289, 1987, pp. 589–598 and with X. G. Wen, Seiberg and Witten the non-perturbative effects (instantons) on the worldsheet of strings.Dine, Seiberg, Wen, Witten Nonperturbative effects on the string world sheet, Nucl. Phys. B, vol. 278, 1986, pp. 769–789 , Part 2, Nucl. Phys. B, vol. 289, 1987, pp. 319–363

He has done extensive research on applications of superstring theory to cosmology.
