Two-loop quarkonium Hamiltonian in annihilation channel
Yukinari Sumino, Takahiro Ueda
We calculate the two-loop quarkonium Hamiltonian in the annihilation channel within the framework of potential-NRQCD effective field theory. The result agrees with the previous cal…
Method to measure quarkonium wave function using decay
Yukinari Sumino
We propose a method that enables a direct experimental probe of the quarkonium wave function defined in potential nonrelativistic QCD (pNRQCD) using the three-body decay of the $B_…
Two-loop term of heavy quarkonium potential
Yukinari Sumino
As a straightforward application of the recently calculated two-loop heavy quarkonium Hamiltonian, we evaluate the two-loop term of the heavy quarkonium potential…
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…
On order renormalons in quarkonium system
Takuya Agemura, Yukinari Sumino
For the heavy quarkonium system we examine renormalons, which are expected to be included in the perturbative series of the pole mass and int…
Understanding Interquark Force and Quark Masses in Perturbative QCD
Y. Sumino
This lecture note presents a self-contained introduction to the theory of a heavy quark-antiquark () system in terms of perturbative QCD. The lecture is intended for non-…
