Glueball masses as a test of the 1/N expansion. Academic Article uri icon


  • We compute the scalar-glueball mass m(0++) in units of the square root of the string tension, for SU(N) gauge theories on the lattice, with N=2,3,5,6. We identify a general-scaling window in which the glueball mass is approximately independent of the lattice spacing, yielding an estimate of m(0++) in the continuum. The estimate is corroborated by the excellent agreement between Hamiltonian and Lagrangean results for N=2,3. The continuum values of m(0++) thus obtained for various values of N are remarkably close to each other, indicating a rapid convergence of the 1/N expansion. 1987 The American Physical Society.
