rescale: Symbol

integrated_loop_scale: Symbol

Bookkeeping scale for integrated vacuum masses and consumed loop measures.

rescale_mass: Symbol

rescale_star: Symbol

pi: Symbol

m_uv_expansion: Symbol

UV mass used only as the auxiliary expansion/deformation scale in local UV series.

This symbol prints as mUVexp. Public runtime output should not depend on this name after the endpoint mass-role collapse.

m_uv_vacuum: Symbol

UV vacuum mass used by integrated counterterms and the vacuum-integral basis.

This symbol prints as mUV and is the public symbolic representative of the general.m_uv runtime setting.

renormalization_localization_scale: Symbol

UV localization scale factor

mu_r_sq: Symbol

sign: Symbol

theta: Symbol

broadcasting_sqrt: Symbol

selected: Symbol

for selecting orientations at generation

expansion: Symbol

For analytic UV profiling

delta_vec: Symbol

For selecting a concete index.

emr_mom: Symbol

Q(<edgeid>, index___)

emr_vec: Symbol

dot: Symbol

external_mom: Symbol

dim: Symbol

coeff: Symbol

localizing_integrand: Symbol

uv_subgraph: Symbol

uv_approx: Symbol

uv_integrate: Symbol

uv_series: Symbol

uv_truncate: Symbol

ct_marker: Symbol

Marker for the ct term in the UV integrand

nc2_1: Symbol

expr: Symbol

num: Symbol

den: Symbol

Denominator wrapper, den(<edge_id>, <momentum>, <mass>, <full_expr>) (no power and should not be multiplied in but divided!).

radius_left: Symbol
