Three loop QCD corrections to heavy quark form factors

Dr. Narayan Rana

We present the three loop QCD corrections to the heavy quark form factors in the case of vector, axial-vector, scalar and pseudo-scalar currents. We evaluate the master integrals applying a new method based on differential equations for general bases, which is applicable for all first
order factorizing systems. The analytic results are expressed in terms of
harmonic polylogarithms and real-valued cyclotomic harmonic polylogarithms.
