LanHEP - a package for automatic generation of Feynman rules from the Lagrangian. Updated version 3.2

TL;DR

LanHEP version 3.2 is a software package that automates the generation of Feynman rules from Lagrangians, now supporting UFO output, color sextet particles, and advanced substitution techniques.

Contribution

This update introduces UFO format support, new particle types, and enhanced routines for defining Feynman rules, improving flexibility and usability.

Findings

Supports UFO output format

Includes color sextet particles

Features new substitution techniques

Abstract

We present a new version 3.2 of the LanHEP software package. New features include UFO output, color sextet particles and new substutution techniques which allow to define new routines.
