About Pran Nath
Professor Nath is coauthor of the “first supergravity” theory with Arnowitt [Phys. Lett.B56, 177 (1975)] and with Arnowitt and Zumino [B56, 81, 1975]. He is coauthor 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)).
