Description
We present an update on including isospin breaking effects in the determination of HVP using C$^{\star}$ boundary conditions. We use QCD+QED configurations with 1+2+1 flavors of Wilson-Clover fermions produced by RC$^{\star}$ collaboration, where the action parameters are chosen to highlight isospin breaking effects. In this series of two talks, we show preliminary results for three $32^3 \times 64$ gauge ensembles with varying values of the fine structure constant, and compare them with the results on the QCD-only ensemble, discussed in the poster presentation by Paola Tavella.
