Physics Contribution:

Prof. DP Roy made pioneering contributions in the wide area of particle and astroparticle physics.
He predicted and presented evidences for exotic meson (tetra-quark) and baryon (penta-quark) states.
The signature for top quark search in terms of a hard isolated lepton and jets, suggested by him, has been widely used in the top quark search at the CERN and Tevatron proton-antiproton colliders, leading to its discovery at the latter in 1995.
He suggested a promising signature for the charged Higgs boson search in its tau lepton decay channel, using the distinctive polarization prediction for tau. This is being currently used in the ongoing search for charged Higgs boson at the Tevatron as well as the Large Hadron Collider at CERN.
Likewise, the missing transverse-momentum signature for Supersymmetric particles suggested by him, is being widely used in the ongoing collider searches for these particles.
In the Golden Years of Solar Neutrino Physics 2000-05, he was deeply involved in analyzing the experimental data with his collaborators to finally provide a unique solution to the long-standing Solar Neutrino puzzle in terms of Neutrino Oscillation with precise massand mixing angle through a series of globally acclaimed papers.
