Two-loop Quarkonium Hamiltonian in Non-annihilation Channel
Go Mishima, Yukinari Sumino, Hiromasa Takaura
We calculate the two-loop heavy quarkonium Hamiltonian within potential-NRQCD effective field theory in the non-annihilation channel. This calculation represents the first non-triv…
Renormalon Subtraction in OPE by Dual Space Approach: Nonlinear Sigma Model and QCD
Yuuki Hayashi, Go Mishima, Yukinari Sumino +1
It is becoming more important to subtract renormalons efficiently from perturbative calculations, in order to achieve high precision QCD calculations. We propose a new framework ``…
Inclusive determination in mass scheme using dual-space-renormalon-subtraction method
Yuuki Hayashi, Go Mishima, Yukinari Sumino +1
We determine from the inclusive semileptonic decay width of the meson with the known NLO perturbative coefficients for the first time in the $\overline{\mathrm{M…
Analytic approximations of processes with massive internal particles
Joshua Davies, Go Mishima, Kay Schönwald +1
We consider two-loop corrections to scattering processes with massive particles in the final state and massive particles in the loop. We discuss the combination of analyti…
Higgs boson contribution to the leading two-loop Yukawa corrections to
Joshua Davies, Go Mishima, Kay Schönwald +2
We analytically compute two-loop Yukawa corrections to Higgs boson pair production in the high-energy limit. Such corrections are generated by an exchange of a Higgs boson between…
ZH production in gluon fusion at NLO in QCD
Long Chen, Joshua Davies, Gudrun Heinrich +5
We present fully differential next-to-leading order results for Higgs production in association with a boson in gluon fusion. Our two-loop virtual contributions are evaluated n…
