Partial Wave Mixing in Hamiltonian Effective Field Theory

We explore partial-wave mixing in the finite volume based on HEFT, and provide the P-Matrix to show the degree of partial-wave mixing. An example of isospin-2 \(\pi\pi\) scattering is used to check the consistency between HEFT and L\"{u}scher's method.
