Jogesh C. Pati (born 1937) is an
Indian-American theoretical physicist
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict natural phenomena. This is in contrast to experimental physics, which uses experi ...

Pati has made pioneering contributions to the notion of a unification of

In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. The Standard Model presently recognizes seventeen distinct particles—twelve fermions and five bosons. As a c ...

and lepton numbers, especially those that would manifest in
proton decay, are likely consequences of such a unification, provide cornerstones of modern particle physics today. The suggestions of Pati and Salam (the
Pati–Salam model) of the symmetry of SU(4)–color,
left–right symmetry, and of the associated existence of right-handed
neutrinos, now provide some of the crucial ingredients for understanding the observed masses of the neutrinos and their oscillations.
Recognition
Pati was awarded the
Dirac Medal for his seminal contributions to a "Quest for Unification" in the year 2000 along with
Howard Georgi and
Helen Quinn.
In 2013, Pati was conferred the honor of
Padma Bhushan, the 3rd highest civilian award from the Govt. of India.
