On the Renormalized Coupling Constant of ( qJ 4 ) 4 Field Theory
نویسنده
چکیده
We show, apart from a correlation inequality for the 6-point function, that the critical or continuum liinit of (11'4)4 lattice field theory is trivial, if some deviations from the mean field theory law are present at the critical point, and if we impose a mild behavior of bare 4-point coupling constant as we approach the critical point. These results are derived from the bounds on the renormalized coupling constant of lattice (\P4)d field theory.

Renormalized sextic coupling constant for the two-dimensional Ising model from field theory
The field-theoretical renormalization group approach is used to estimate the universal critical value g∗ 6 of renormalized sextic coupling constant for the two-dimensional Ising model. A four-loop perturbative expansion for g6 is calculated and resummed by means of the Padé-Borel-Leroy technique. Under the optimal value of the shift parameter b, providing the fastest convergence of the iteratio...

Tachyon Condensation and Background Independent Superstring Field Theory
We study quantum corrections at the one loop level in open superstring tachyon condensation using the boundary string field theory (BSFT) method. We find that the tachyon field action has the same form as at the disc level, but with a renormalized effective coupling λ = g s e −T /4 (g s is the renormalized dimensionless closed string coupling, e /4 is the tachyonic field expectation value) and ...
