Pseudo-scalar Form Factors at Three Loops in QCD
Taushif Ahmed, Thomas Gehrmann, Prakash Mathews +2
The coupling of a pseudo-scalar Higgs boson to gluons is mediated through a heavy quark loop. In the limit of large quark mass, it is described by an effective Lagrangian that only…
Pseudo-scalar Higgs Boson Production at Threshold NLO and NLL QCD
Taushif Ahmed, M. C. Kumar, Prakash Mathews +2
We present the first results on the production of pseudo-scalar through gluon fusion at the LHC to NLO in QCD taking into account only soft gluon effects. We have used the effe…
Spin-2 Form Factors at Three Loop in QCD
Taushif Ahmed, Goutam Das, Prakash Mathews +2
Spin-2 fields are often candidates in physics beyond the Standard Model namely the models with extra-dimensions where spin-2 Kaluza-Klein gravitons couple to the fields of the SM.…
RG improved Higgs boson production to NLO in QCD
Taushif Ahmed, Goutam Das, M. C. Kumar +2
The recent result on the third order correction to the Higgs boson production through gluon fusion by Anastasiou et al. [1] not only provides a precise prediction with reduced scal…
