Pseudo-scalar Higgs boson production at threshold N $$^3$$ 3 LO and N $$^3$$ 3 LL QCD
2016
European Physical Journal C: Particles and Fields
We present the first results on the production of pseudo-scalar through gluon fusion at the LHC to N^3LO in QCD taking into account only soft gluon effects. We have used the effective Lagrangian that describes the coupling of pseudo-scalar with the gluons in the large top quark mass limit. We have used recently available quantities namely the three loop pseudo-scalar form factor and the third order universal soft function in QCD to achieve this. Along with the fixed order results, we also
