Dr Mitra has done pioneering work on the nuclear three-body problem providing an exact solution in terms of separable potentials. This work of Dr Mitra has generated a good deal of interest in the nuclear physics world.
In the field of hadron physics, Dr Mitra showed the incompatibility of Fermi statistics for quarks with the observed monotonic behaviour of the proton form factor with momentum transfer. He gave a new classification of hadron resonances in terms of s-wave quark-quark forces, in conformity with the observed pattern of 56 (even) and 70 (odd) representations of the group SU(6) x 0(3), and their Regge recurrences. He has developed a comprehensive phenomenological theory of relativistic interactions of hadron resonances with vector and pseudoscalar mesons in terms of the quark model.
