  • Das, Saurya; Majumdar, Parthasarathi (American Physical SocietyInstitute of Mathematical Sciences, 1994)
    The amplitude for the scattering of a point magnetic monopole and a point charge, at center-of- mass energies much larger than the masses of the particles, and in the limit of low momentum transfer, is shown to be ...
  • Das, Saurya; Majumdar, Parthasarathi (American Physical SocietyInstitute of Mathematical SciencesInternational Centre for Theoretical Physics, 1995)
    The scattering of pointlike particles at a very large center-of-mass energies and fixed low momentum transfers, occurring due to both their electromagnetic and gravitational interactions, is reexamined in the particular ...
  • Das, Saurya; Majumdar, Parthasarathi (Elsevier BV North HollandInstitute of Mathematical Sciences (India)International Centre for Theoretical Physics, 1995)
    We consider possible mixing of electromagnetic and gravitational shock waves, in the Planckian energy scattering of point particles in Minkowski space, By boosting a Reissner-Nordstriim black hole solution to the velocity ...
  • Das, Saurya; Majumdar, Parthasarathi (Indian Academy of SciencesInstitute of Mathematical Sciences (India), 1998)
    We discuss an approach to compute two-particle scattering amplitudes for spinless light particles colliding at Planckian centre-of-mass energies, with increasing momentum transfer away from the eikonal limit. The leading ...
  • Das, Saurya; Majumdar, Parthasarathi (American Physical SocietyInstitute of Mathematical Sciences (India), 1997)
    Approximating light charged pointlike particles in terms of ~nonextremal! dilatonic black holes is shown to lead to certain pathologies in Planckian scattering in the eikonal approximation, which are traced to the presence ...
