  • Balachandran, A. P.; Borchardt, S.; Chang, S. S.; Stern, Allen; Cahalan, R.; Ramachandran, R.; Rupertsberger, H. (American Physical Society, 1978-02-15)
    We study the analyticity in cosθ of the exact quantum-mechanical electric-charge-magnetic-monopole scattering amplitude by ascribing meaning to its formally divergent partial-wave expansion as the boundary value of an ...
  • Balachandran, A. P.; Barducci, A.; Lizzi, F.; Rodgers, V. G. J.; Stern, Allen (American Physical Society, 1984-03-12)
    It shown that the chiral model with SU (3) flavor symmetry predicts a dibaryon state of low mass M(M≈2.2 GeV). It is electrically neutral and is an SU (3) singlet with JP=0+. It corresponds to a six-quark state found in ...
  • Balachandran, A. P.; Nair, V. P.; Rajeev, S. G.; Stern, Allen (American Physical Society, 1982-10-18)
    Skyrme has shown that the SU ⊗ SU(2) chiral model has nontrivial topological sectors with static solutions for suitable Lagrangians. The baryon number B and strangeness of these sectors have been studied, and the existence ...
  • Balachandran, A. P.; Stern, Allen; Skagerstam, B. S. (American Physical Society, 1979-07-15)
    Equations of motion and the Lagrangian formalism for extended objects coupled to Abelian and non-Abelian gauge fields are developed. These equations are minimal generalizations of the corresponding equations for point ...
  • Balachandran, A. P.; Borchardt, S.; Stern, A. (American Physical Society, 1978-06-15)
    A new Lagrangian L is proposed for the description of a particle with a non-Abelian charge in interaction with a Yang-Mills field. The canonical quantization of L is discussed. At the quantum level L leads to both irreducible ...
  • Balachandran, A. P.; Stern, Allen; Trahern, G. (American Physical Society, 1979-04-15)
    In the usual formulation of nonlinear models (such as chiral models), there is invariance under a nonlinear realization of a group GF which becomes linear when restricted to a subgroup HF. We formulate them so that they ...
  • Balachandran, A. P.; Stern, Allen (American Physical Society, 1982-09-15)
    A finite number of nonlocal conservation laws are found in the Nambu-Goto string model. An infinite number of conserved currents may be obtained by embedding the string in more than 3 + 1 space-time dimensions. These ...
  • Stern, Allen; Balachandran, A. P.; Borchardt, S.; Chang, S. S.; Stern, A.; Cahalan, R.; Ramachandran, R.; Rupertsberger, H. (American Physical Society, 1978-02-15)
    A semiclassical approximation derived directly from the Feynman path integral is employed in the study of electric-charge-magnetic-monopole scattering. We show that this approximation, unlike perturbation theory, is ...
