@article{Ahmed2016PseudoscalarHB, title={Pseudo-scalar Higgs boson production at threshold N\$\$^3\$\$3LO and N\$\$^3\$\$3LL QCD}, author={Taushif Ahmed and M. C.

We present the first results on the production of pseudo-scalar Higgs boson through gluon fusion at the LHC to N$$^3$$3LO in QCD taking into account only soft-gluon effects. We have used the effective Lagrangian that describes the coupling of the pseudo-scalar Higgs boson with the gluons in the large top quark mass limit. We have used quantities that have recently become available, namely the three-loop pseudo-scalar Higgs boson form factor and the third order universal soft function in QCD to… Expand
