SUGRA models, and specifically mSUGRA, are currently the leading candidates for discovery at the Fermilab Tevatron and at the CERN Large Hadron Collider (LHC).
[11] His early work concerns the invention of effective Lagrangian method, the first current algebra analysis of pion-pion scattering[12] and solution to the notorious U(1) problem.
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.
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".
An international conference was held at Northeastern University March 17–20, 2003 celebrating 20 years since the invention of SUGRA unified model of which he was a co-author.
