The derivative of the topological susceptibility at zero momentum and an estimate of $η^{'}$ mass in the chiral limit

J. Pasupathy, J. P. Singh, R. K. Singh +1

The anomaly-anomaly correlator is studied using QCD sum rules. Using the matrix elements of anomaly between vacuum and pseudoscalars $π, e t a$ and $η^{'}$ , the derivative of correlator…

Gluonic contribution to the nucleon self-energy in an effective theory

Alka Upadhyay, J. P. Singh

Gluonic contributions to the self-energy of a nucleon have been investigated in an effective theory. The couplings of the topological charge density to nucleons give rise to OZI vi…
