Question: FeynmanIntegral:-Evaluate() Not Evaluating Integrals in Maple 2024

I have Maple 2024 and successfully loaded the FeynmanIntegral package with:

with(Physics); with(FeynmanIntegral);

Maple confirms that FeynmanIntegral is loaded by displaying:

[Evaluate, ExpandDimension, FromAbstractRepresentation, Parametrize, Series, SumLookup, TensorBasis, TensorReduce, ToAbstractRepresentation, epsilon, varepsilon]

However, when I attempt to evaluate a Feynman integral, Maple only displays the unevaluated expression instead of computing it:

Delta(q); %FeynmanIntegral(1/p^2*1/(p + q)^2, p);

And explicitly calling Evaluate() does not compute the result:

Evaluate(Delta(q));

What I Have Tried:

  1. Using Evaluate() explicitly:

    FeynmanIntegral:-Evaluate(1 / (p^2 * (p + q)^2), p);

    Result: No evaluation, only displays the input.

  2. Assigning the integral to a variable before evaluating:

    I := FeynmanIntegral(1 / (p^2 * (p + q)^2), p); Evaluate(I);

    Result: Still does not evaluate.

  3. Using dimension= instead of d= when specifying the spacetime dimension:

    FeynmanIntegral:-Evaluate(1 / (p^2 * (p + q)^2), p, dimension = 4 - 2*epsilon);

    Result: No evaluation.

  4. Checking if FeynmanIntegral functions exist:

    showstat(FeynmanIntegral);

    Result: The package seems loaded, but it does not execute calculations.

Expected Behavior:

I expect FeynmanIntegral:-Evaluate(...) to automatically compute the dimensional integral using Feynman rules and return a result.

Questions for the MaplePrimes Community:

  1. Is FeynmanIntegral:-Evaluate() broken in Maple 2024?
  2. Are there additional setup steps needed to enable full functionality?
  3. Has anyone successfully used FeynmanIntegral for automatic dimensional integration?
  4. Are there alternative Maple functions/packages for computing Feynman integrals in dimensional regularization?

Any help would be greatly appreciated!
