Pran Nath (physicist)

His main area of research is in the fields of supergravity and particle physics beyond the standard model. He is one of the originators of the first supergravity theory in 1975.{{cite journal | last1=Nath | first1=P. | last2=Arnowitt | first2=R. | title=Generalized super-gauge symmetry as a new framework for unified gauge theories | journal=Physics Letters B | publisher=Elsevier BV | volume=56 | issue=2 | year=1975 | issn=0370-2693 | doi=10.1016/0370-2693(75)90297-x | pages=177–180| bibcode=1975PhLB...56..177N }}{{cite journal | last1=Arnowitt | first1=R. | last2=Nath | first2=P. | last3=Zumino | first3=B. | title=Superfield densities and action principle in curved superspace | journal=Physics Letters B | publisher=Elsevier BV | volume=56 | issue=1 | year=1975 | issn=0370-2693 | doi=10.1016/0370-2693(75)90504-3 | pages=81–84| bibcode=1975PhLB...56...81A }} In 1982 in collaboration with Richard Arnowitt and Ali Hani Chamseddine, he developed the field of Applied SupergravityP.

SUGRA models, and specifically mSUGRA, are currently the leading candidates for discovery at the Fermilab Tevatron and at the CERN Large Hadron Collider (LHC).

He was born in West Punjab, British India in 1939, and is of Kashmiri descent. He received his bachelor's degree in Science at the University of Delhi in 1958, and his Ph.D. degree from Stanford University in 1964. He taught at the University of California, Riverside (1964–65) and was Andrew Mellon Fellow at the University of Pittsburgh (1965–66). Since 1966 he has been at Northeastern University. He has held visiting positions at TIFR, Mumbai under the United Nations Development Program, at the University of California, Santa Barbara, at Bonn, CERN, Heidelberg and Munich. He was co-chair of the conference "Gauge Theories and Modern Field Theory", in 1975, and founding chair in 1990 of the annual PASCOS symposium (Particle physics, String theory and Cosmology), and also the founding chair in 1993 of the annual conference SUSY. In 2004 PASCOS symposium held a special Pran Nath Festschrift honouring his "pioneering contributions over four decades in the fields of high energy theory, supersymmetry, supergravity, and unification".G.
