Continuum perturbative correlator theorem for the Abelian Higgs model

Let Aμ,ϕ\\{A^{\mu},\phi\\} be the particle content of the Abelian Higgs model. Let E[Aμ(x1)ϕ(x2)ϕ(xn1)Aν(xn)]\mathbb{E}[A^{\mu}(x_1)\phi(x_2)\cdots\phi(x_{n-1})A^{\nu}(x_n)] be an arbitrary point correlator, and let Γn(n1,n2)\Gamma_n(\\{n_1,n_2\\}) count lattice embeddings of Feynman diagrams connecting the photon and scalar points, with n1n_1 interaction terms in which a photon path terminates at a ϕ\phi and n2n_2 terms in which ϕ\phi has a four-point vertex. The scalar paths are constrained to lie along An\mathcal{A}_n, while the photon paths are constrained to its intersection with a:dn(0,a)=0\\{\vec a:d_n(0,\vec a)=0\\}. Let Tcont\mathcal{T}_{\mathrm{cont}} denote the continuum transformation and let II be the accumulated Minkowski length of the scalar paths.

Abelian Higgs correlator theorem. The correlator may be obtained by applying Tcont\mathcal{T}_{\mathrm{cont}} to

n1+n2=1qn1λn2Γn(n1,n2),\sum_{n_1+n_2=1}^{\infty}q^{n_1}\lambda^{n_2}\Gamma_n(\\{n_1,n_2\\}),

then taking nn\to\infty and Fourier transforming from II to λ(12Φ)\lambda(1-2\Phi).

This is presented as a theorem motivated by perturbation theory in the Abelian Higgs model. The parser supplies no resolution evidence beyond the source's theorem label, and several symbols, including Tcont\mathcal{T}_{\mathrm{cont}} and An\mathcal{A}_n, are only partially defined in the supplied context.
