Exotic-Hadron Signature by Constituent-Counting Rule in Perturbative QCD
Wen-Chen Chang, H. Kawamura, S. Kumano +1
We explain a method to find internal quark configurations of exotic hadron candidates by using the constituent counting rule. The counting rule was theoretically predicted in pertu…
Impacts of B-factory measurements on determination of fragmentation functions from electron-positron annihilation data
M. Hirai, H. Kawamura, S. Kumano +1
Fragmentation functions are determined for the pion and kaon by global analyses of charged-hadron production data in electron-positron annihilation. Accurate measurements were repo…
On enhanced corrections from quasi-degenerate states to heavy quarkonium observables
Yuichiro Kiyo, Go Mishima, Yukinari Sumino
It is well known that in perturbation theory existence of quasi-degenerate states can rearrange the order counting. For a heavy quarkonium system, naively, enhanced effects (-ch…
Near-threshold production of heavy quarks with QQbar_threshold
M. Beneke, Y. Kiyo, A. Maier +1
We describe the QQbar_threshold library for computing the production cross section of heavy quark-antiquark pairs near threshold at electron-positron colliders. The prediction incl…
