NNLO QCD Corrections to Exclusive Production in Electron-Positron Collision
Long-Bin Chen, Yi Liang, Cong-Feng Qiao
Based on the NRQCD factorization formalism, we calculate the next-to-next-to-leading order QCD corrections to the heavy quarkonium production associated with a photon a…
Two-Loop integrals for CP-even heavy quarkonium production and decays
Long-Bin Chen, Yi Liang, Cong-Feng Qiao
By employing the method of differential equations, we compute the various types of two-loop master integrals involved in CP-even heavy quarkonium exclusive production and decays. A…
X(16.7) as the Solution of NuTeV Anomaly
Yi Liang, Long-Bin Chen, Cong-Feng Qiao
A recent experimental study of excited decay to its ground state reveals an anomaly in the final states angle distribution. This exceptional result is attributed to a ne…
X(16.7) Production in Electron-Position Collision
Jun Jiang, Long-Bin Chen, Yi Liang +1
The anomaly found in the excited nuclear transition to its ground state is attributed to a spin-1 gauge boson . To hunt for this boson, we propose two traps:…
Magnetic moment of the positronium ion and virial relations
Andrzej Czarnecki, Yi Liang
We derive a hypervirial relation for the positronium ion, a three-body bound state of two electrons and a positron. It relates expectation values of three operators and reconciles…
Anomalous magnetic moment of the positronium ion
Yi Liang, Paul L. McGrath, Andrzej Czarnecki
We determine the gyromagnetic factor of the positronium ion, a three-body system consisting of two electrons and a positron, including first relativistic corrections. We find that…
Muon decay spin asymmetry
Fabrizio Caola, Andrzej Czarnecki, Yi Liang +2
We compute the spin asymmetry of the muon decay through O(alpha^2) in perturbative QED. These two-loop corrections are about a factor five (twenty) smaller than the current statist…
Photon-photon scattering: a tutorial
Yi Liang, Andrzej Czarnecki
Long-established results for the low-energy photon-photon scattering, gamma gamma --> gamma gamma, have recently been questioned. We analyze that claim and demonstrate that it is i…
