Convergent expansions for excited glueball masses in 2+1 strongly coupled lattice gauge theories
It is known that the mass spectrum of a strongly coupled (..beta.. = 2/g/sup 2/ small) 2+1 Wilson action lattice gauge theory contains a mass m/sub 0/approx.-4 ln ..beta.. and two excited masses m/sub 1/, m/sub 2/approx.-6 ln ..beta.. and that m/sub 0/+4 ln ..beta.. has a convergent expansion in powers of ..beta... We show that m/sub 1/, m/sub 2/ admit convergent expansions of the form -6 ln ..beta..+r(..beta..), where r(..beta..) is analytic at ..beta.. = 0. Furthermore, a finite lattice algorithm is given for determining c/sub n/, the nth ..beta.. = 0 Taylor coefficient of r(..beta..). Here, c/sub n/ only depends on a finite number of ..beta.. = 0 Taylor series coefficients of the plaquette--plaquette, plaquette--double plaquette, and double plaquette--double plaquette truncated correlation functions at a finite number of points. For the gauge group Z/sub 2/, by duality, m/sub 1/, m/sub 2/ map to bound states of the low-temperature Ising model; a possible relation between an increasing number of bound states and roughening is discussed.
