Spin-dependent polarizabilities of heavy vector mesons
Hao Dang, Liang-Zhen Wen, Yan-Ke Chen +1
We investigate the spin-dependent electromagnetic polarizabilities of the heavy vector mesons \(D^*\) and \(B^*\) in heavy meson chiral perturbation theory up to \(\mathcal O(p^3)\…
Electromagnetic polarizabilities of the triplet hadrons in heavy hadron chiral perturbation theory
Hao Dang, Liang-Zhen Wen, Yan-Ke Chen +1
We investigate the electromagnetic polarizabilities of singly heavy mesons and doubly heavy baryons within the framework of heavy hadron chiral perturbation theory up to $\mathcal{…
QCD anomalies in electromagnetic processes: A solution to the puzzle
Zanbin Xing, Hao Dang, M. Atif Sultan +2
In this work, the form factor is calculated within the Dyson-Schwinger equations framework using a contact interaction model within the so-called modified rainbow ladder t…
The chiral anomaly and the pion transition form factor: beyond the cutoff
Hao Dang, Zanbin Xing, M. Atif Sultan +2
In the presence of a momentum cutoff, effective theories seem unable to faithfully reproduce the so called chiral anomaly in the Standard Model. A novel prospect to overcome this r…
