antares-hep - v0.7.0

[0.7.0] - 2025-04-24 - Terms refactoring

Added

• Support for evaluating Terms that return a numpy array, e.g. for amplitude coefficients with massive fermions (open spin indices).
• Slicing as alternative to scalings, works for arbitrary q-ring (not yet available in public version).

Changed

• Refactored Terms, Term, Numerator, Denominator to be based on Monomial and Polynomial from syngular.
• Scalings functions accept invariants list as optional kwarg.
• Mass dimension and Phase weights can now be manually set (changed from property to setter/getter).
• LoadResults can now be passed multiplicity as kwarg.
• Simplified several functions related to Terms by using __str__ and __rstr__ rather than reimplementing them.

Fixed

• Invariant patterns are provided by lips.

antares-hep - v0.6.2

[0.6.2] - 2025-01-21

Changed

• Numerical_Methods.do_single_collinar_limits and related functions now accept a list of invariants as optional kwarg.

Fixed

• Fixed issue where Terms.__rstr__ would fail to properly load a numerator with mass dependence.

antares-hep - v0.6.1

[0.6.1] - 2024-12-16

Added

• TermsList class now replaces basis related functions.

Fixed

• Fixed issue where Particles objects used in Numerical_Methods.mass_dimensions and .phase_weights would not all trigger an lru_cache hit, likely due to mutable nature of the object (despite hasing and equality being correctly implemented).
