AntCalc

New in 0.3.0 β1: massive A30 now has a derived MX30 master-basis closure and an end-to-end integrated route; invariant-only A22 builds are also available. D30 remains an experimental research track.

AntCalc is a Wolfram Language package that builds and integrates QCD antenna functions. The main workflow has two steps:

BuildAntenna[...] → IntegrateAntenna[...]

BuildAndIntegrateAntenna[...] runs these steps in sequence. AntCalc is thesis research software. The massless routes are the stable release surface; massive A30 is a beta extension and D30 remains experimental.

Status

Current development release: AntCalc 0.3.0 β1.

The current release target is the massless antenna workflow for the NNLO SMQCD R-ratio, with a beta massive-A30 extension. Before using a route in a calculation, read the route-status matrix.

AntCalc is active, unpublished thesis research software. It is shared for evaluation and academic discussion; reuse, redistribution, and relicensing require prior written permission from the relevant rights holder or holders. See NOTICE for the current distribution position.

Install and load

After cloning the repository, install the paclet once from a Wolfram notebook or kernel:

repoRoot = "/path/to/antenna_pipeline";
archive = CreatePacletArchive[repoRoot, $TemporaryDirectory];
PacletInstall[archive];

Then restart the kernel and load AntCalc normally:

<< AntCalc`

If the paclet was installed while the notebook kernel was already running, evaluate PacletDataRebuild[], restart the kernel, and try again.

While actively editing a cloned checkout, load its current source directly instead of the installed paclet copy:

repoRoot = "/path/to/antenna_pipeline";
Get[FileNameJoin[{repoRoot, "AntennaPipeline.wl"}]]

Quick start

<< AntCalc`

(* Unintegrated tree-level NLO antenna. *)
a30 = BuildAntenna[A, 3, 0];

(* One-shot construction and integration. *)
intA30 = BuildAndIntegrateAntenna[A, 3, 0];

(* The explicitly modular equivalent. *)
a30Object = BuildAntenna[A, 3, 0, IntegrableForm -> True];
intA30Direct = IntegrateAntenna[a30Object];

Dependencies

Supported workflows require Wolfram Language, FeynCalc, FeynArts, and FeynHelpers. IBP-backed integration also requires LiteRed2. Keep the bundled basis and runtime-master files when copying or cloning the repository.

The current beta toolchain is:

FeynCalc 10.2.1 · FeynArts 3.12 (27 Mar 2025) ·
FeynHelpers 2.0.0 · FeynCalcLegacy 1.0.0
LiteRed2 2.025 β

Scope

AntCalc does not currently provide a public D30 route or complete SUSY/HiggsEFT R-ratio workflows. The massive-A30 beta route has a derived master substitution and fresh-kernel qualification through ExpansionOrder -> 2; deeper epsilon orders are not yet claimed. See the route-status matrix for the exact limits.
