Ising field theory in a magnetic field: φ 3 coupling at T > Tc
Abstract We study the “three particle coupling” Γ 11 1 ξ $$ {\Gamma}_{11}^1\left(\xi \right) $$ , in 2d Ising Field Theory in a magnetic field, as the function of the scaling parameter ξ := h/(−m)15/8, where m ∼ T c − T and h ∼ H are scaled deviation from the critical temperature and scaled external...
