Research Interests

Strong, electromagnetic, and weak interactions are studied at high energy in pion-nucleon, nucleon-nucleus, and nucleus-nucleus interactions. Study of quark-gluon plasma by using heavy-ion beams from CERN Geneva (Switzerland) and from Brookhaven National Laboratory, Long Island (NY), in nuclear emulsion. For this research work, we have more than half a dozen good microscopes, including Leitz Ortholux, Bausch and Lomb microscopes equipped with Brower Stage, Cook's scattering microscope, three Koristka scattering microscopes that are being used to study the scattering of very high-energy particles, Leitz UMW-II large scattering microscope with digital readout for x-y motion with an accuracy of 0.1 mm, and an optical projectile rotary stage with 360 degree rotation.

Selected Projects

  • Characteristics of charged particle multiplicities distribution in relativistic heavy-ion interactions, especially with Pb beam at 160A GeV, and compare results with other heavy-ion beams from CERN and BNL
  • Multifragmentation of heavy nuclei at relativistic energies >10A GeV
  • Search for short-lived exotic particles in heavy-ion interactions at 10-200A GeV
  • Nuclear collective flow with heavy fragments (Z>2). How it varies with (i) PF's charge, (ii) the impact parameter, (iii) the size of the target nucleus
