Nucleon matrix elements of axial anomaly, axial currents and pseudoscalar currents in the QCD sum rule
Janardan Prasad Singh
We have analyzed one-nucleon matrix elements of current-current correlators; the currents consist of pseudoscalar octet, isovector and isoscalar currents, axial anomaly, and axial…
Pion couplings with low-lying nucleon resonances
Janardan Prasad Singh
We have calculated coupling constants of a neutral pion with the lowest two nucleon resonances. This includes both the diagonal as well as non-diagonal coupling constants involving…
Eta-nucleon and eta-prime-nucleon coupling constants in QCD and the role of gluons
Janardan P. Singh, Shesha D. Patel
Coupling constants of and mesons with nucleons have been calculated using the method of QCD sum rules. Starting from vacuum-to-meson correlation function of interp…
Sub-leading power corrections to transition form factors of and mesons from twist-six contributions
Janardan P. Singh, Shesha D. Patel
Using collinear factorization, we have calculated twist-six corrections to and transition form factors in QCD. Only a sub-set of light-cone operators of twist-si…
Singlet axial-vector coupling constant of the nucleon in QCD without instantons
Janardan P. Singh
We have analyzed axial-vector current-current correlation functions between one-nucleon states to calculate the singlet axial-vector coupling constant of the nucleon. The octet-oct…
Light quark pseudoscalar densities and anomaly matrix elements for η and η' mesons
Janardan Prasad Singh
Matrix elements of flavor-diagonal light quark pseudoscalar densities and axial anomaly operators between vacuum and η and η' meson states have been determined. This has been done…
