Abstract: Physical review / D 97(9), 094022 (2018). doi:10.1103/PhysRevD.97.094022<br />We compute the two-loop QCD corrections to the heavy quark form factors in case of the vector, axial-vector, scalar and pseudo-scalar currents up to second order in the dimensional parameter $\epsilon = (4-D)/2$. These terms are required in the renormalization of the higher order corrections to these form factors.<br />Published by APS, Woodbury, NY
