Professor Nath is co-author of the “first supergravity” theory with Arnowitt [Phys. Lett.B56, 177 (1975)] and with Arnowitt and Zumino [B56, 81, 1975]. He is co-author of the invention of mSUGRA model with Chamseddine and Arnowitt [Phys. Rev. Lett. 49, 970 (1982)]. mSUGRA is currently a leading candidate for discovery at the Large Hadron Collider. His other contributions include proposal of the trileptonic signal for discovery of supersymmetry [Mod. Phys. Lett. A2, (1987) 331], the first computation of supersymmetric contributions to the anomalous magnetic moment of the muon [Z. Phys. C26, 407 (1984)], discovery of a new branch (the hyperbolic branch) of radiative breaking of the electroweak symmetry [Phys. Rev. D58, 096004 (1998)], suppression of CP violation effects and the cancellation mechanism in supersymmetry [Phys. Rev. Lett. 66, 2565 (1991); Phys. Rev. D58, 111301 (1998)], the first precision analyses of sparticle spectrum and of the relic density [Phys. Rev. Lett. 69, 725 (1992), Phys. Rev. Lett. 70, 3696 (1993)], and the first complete analysis of proton decay in SUGRA models [Phys. Rev. D32, 2348 (1985)].
His other contributions include development of the effective Lagrangian approach to pion physics, solution to the notorious U(1) problem [Phys. Rev. D23, 473 (1981)], contemporaneous to the work of Veneziano and Witten, the first analytic computation of SO(10) interactions [Phys. Lett. B 506, 68 (2001), Nucl. Phys. B618, 138 (2001)], and more recently the Stueckelberg extension of the Standard Model and of the MSSM [Phys. Lett. B 586, 366 (2004), Nucl. Phys. B681, 77 (2004)].

Pran Nath, Northeastern’s longest-tenured professor, pursues the beautiful mysteries of physics
After 58 years, the world-renowned researcher continues to explore the secrets of the universe. His explorations are a mystery to most of us, conducted with a stream-of-consciousness array of mathematical symbols reinforced by terminology that sounds like English taken to the third power. -
New models of Big Bang by Northeastern physicists show that visible universe and invisible dark matter co-evolved
Physicists have long theorized that our universe may not be limited to what we can see. By observing gravitational forces on other galaxies, they’ve hypothesized the existence of “dark matter,” which would be invisible to conventional forms of observation. Pran Nath, the Matthews Distinguished University Professor of physics at Northeastern University, says that “95% of... -
What is ‘Fallout’? Physicist breaks down the science of Amazon’s sci-fi show and the horrifying reality of nuclear radiation
The world ends on Oct. 23, 2077, in a series of radioactive explosions –– at least in the world of “Fallout,” a post-apocalyptic video game series that has now been adapted into a blockbuster TV show on Amazon’s Prime Video. The literal fallout that ensues creates a post-apocalyptic United States that is full of mutated... -
