  1. 26. Pauli-Villars regularization of non-Abelian gauge theories
    John Hiller (University of Minnesota-Duluth)

    Invited talk
    As an extension of earlier work on QED, we construct a BRST-invariant Lagrangian for SU(N) Yang-Mills theory, regulated by the inclusion of massive Pauli-Villars (PV) gluons. The underlying gauge symmetry for massless PV gluons is generalized to accommodate the PV-index-changing currents that are required by the regularization. Auxiliary adjoint scalars are used, in a mechanism due to...

  2. 62. Two-dimensional light-front massless fields and solvable models

    Oral contribution
    One of the apparent problems of light front field theory has been a lack of description of two-dimensional massless fields. We show how both the massless scalar and fermion fields can be recovered as massless limits of the two-dimensional massive fields and consistenly quantized without any loss of physical information. Bosonization of the ligh-front (LF) fermion field then follows in a...

  3. 41. Light-Front Quantization of the Restricted Gauge Theory of $~QCD_{2}~$
    Prof. Daya Shankar Kulshreshtha (Department of Physics and Astrophysics, University of Delhi, Delhi-110007, India)
    23/09/2015, 12:45
    Oral contribution
    In this talk, we study the light-front quantization of the restricted gauge theory of $~QCD_{2}~$ $~\grave{a}~$ la Cho et al., using Hamiltonian, path integral and BRST quantization procedures.
