The $γ γ \to π^{0} π^{0}$ and $η \to π^{0} γ γ$ Transitions in the Extended NJL Model

Johan Bijnens, Ansar Fayyazuddin, Joaquim Prades

We calculate within the Extended Nambu--Jona-Lasinio model the leading in $1/ N_{c}$ contribution to $γ γ \to π^{0} π^{0}$ to all orders in the external momenta and quark masses. This result…

The Chiral Dirac Determinant According to the Overlap Formalism

Per Ernstrom, Ansar Fayyazuddin

The chiral Dirac determinant is calculated using the overlap formalism of Narayanan and Neuberger. We compare the real and imaginary parts of the determinant with the continuum res…
