Tenth-Order Electron Anomalous Magnetic Moment --- Contribution of Diagrams without Closed Lepton Loops
T. Aoyama, M. Hayakawa, T. Kinoshita +1
This paper presents a detailed account of evaluation of the electron anomalous magnetic moment a_e which arises from the gauge-invariant set, called Set V, consisting of 6354 tenth…
Positronium resonance contribution to the electron g-2
Masashi Hayakawa
Recently a few authors pointed out that the positroniums give rise to an extra contribution to the electron with the magnitude comparable to the perturbative effect,…
Complete Tenth-Order QED Contribution to the Muon g-2
Tatsumi Aoyama, Masashi Hayakawa, Toichiro Kinoshita +1
We report the result of our calculation of the complete tenth-order QED terms of the muon g-2. Our result is a_μ^{(10)} = 753.29 (1.04) in units of (α/π)^5, which is about 4.5 s.d.…
Tenth-Order QED Contribution to the Electron g-2 and an Improved Value of the Fine Structure Constant
Tatsumi Aoyama, Masashi Hayakawa, Toichiro Kinoshita +1
This paper presents the complete QED contribution to the electron g-2 up to the tenth order. With the help of the automatic code generator, we have evaluated all 12672 diagrams of…
Tenth-Order QED Lepton Anomalous Magnetic Moment --- Eighth-Order Vertices Containing a Second-Order Vacuum Polarization
Tatsumi Aoyama, Masashi Hayakawa, Toichiro Kinoshita +1
This paper reports the evaluation of the tenth-order QED contribution to the lepton g-2 from the gauge-invariant set of 2072 Feynman diagrams, called Set IV, which are obtained by…

Tatsumi Aoyama, Masashi Hayakawa, Toichiro Kinoshita +1
This paper reports the values of contributions to the electron g-2 from 300 Feynman diagrams of the gauge-invariant Set III(a) and 450 Feynman diagrams of the gauge-invariant Set I…
Tenth-order lepton g-2: Contribution from diagrams containing a sixth-order light-by-light-scattering subdiagram internally
T. Aoyama, K. Asano, M. Hayakawa +3
This paper reports the result of our evaluation of the tenth-order QED correction to the lepton g-2 from Feynman diagrams which have sixth-order light-by-light-scattering subdiagra…
Eighth-Order Vacuum-Polarization Function Formed by Two Light-by-Light-Scattering Diagrams and its Contribution to the Tenth-Order Electron g-2
T. Aoyama, M. Hayakawa, T. Kinoshita +2
We have evaluated the contribution to the anomalous magnetic moment of the electron from six tenth-order Feynman diagrams which contain eighth-order vacuum-polarization function fo…
QED in finite volume and finite size scaling effect on electromagnetic properties of hadrons
Masashi Hayakawa, Shunpei Uno
On account of its application to the present and future analysis of the virtual photon correction to the hadronic properties by means of lattice QCD simulation, we initiate the stu…
Revised value of the eighth-order QED contribution to the anomalous magnetic moment of the electron
T. Aoyama, M. Hayakawa, T. Kinoshita +1
We have carried out a new evaluation of the eighth-order contribution to the electron g-2 using FORTRAN codes generated by an automatic code generator gencodeN. Comparison of the "…
Revised value of the eighth-order electron g-2
T. Aoyama, M. Hayakawa, T. Kinoshita +1
The contribution to the eighth-order anomalous magnetic moment (g-2) of the electron from a set of diagrams without closed lepton loops is recalculated using a new FORTRAN code gen…
Comment on the sign of the pseudoscalar pole contribution to the muon g-2
Masashi Hayakawa, Toichiro Kinoshita
We correct the error in the sign of the pseudoscalar pole contribution to the muon g-2, which dominates the O(alpha^3) hadronic light-by-light scattering effect. The error originat…
Muon g-2 and New Physics
M. Hayakawa
Here we invoke the current and future perspective on muon measurement when asking what the muon could tell about the underlying structure concerning with the hierarchy…
Measurement of CPT violation in the neutral kaon system
M. Hayakawa
The basic feature of the measurement of CPT violation in the neutral kaon system is overviewed beginning with noting the physical implication of CPT violation. After describing $K^…
Mass hierarchy from compositeness hierarchy in supersymmetric gauge theory
M. Hayakawa
The possibility that the mass hierarchy is intimately associated with the compositeness level of the matters is proposed in supersymmetric gauge theory. This implies, for instance,…
