Differential decay rates of CP-even and CP-odd Higgs bosons to top and bottom quarks at NNLO QCD

$h \rightarrow b\bar{b}$ is the most probable decay channel of the Standard Model Higgs, 
and is finally observed recently at the LHC in the VH-events.
On the other hand, we also know that the Standard Model is not the whole story, and there are a wealth 
of CP-even and odd heavy Higgs bosons predicted in many extensions of the Standard Model  
where they typically couple to heavy quarks among others.
In this talk I will discuss the calculation of the decay of a neutral Higgs boson of arbitrary CP nature to a massive quark antiquark pair at next-to-next-to-leading order in perturbative QCD. 
The computation is made at the differential level using the antenna subtraction framework.
Since the dependence on quark mass is kept consistently in the set up, we hope that this result will be useful in the future analysis of Higgs decay into bottom quarks produced in association with a massive vector boson at LHC.
