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…
A glimpse into pion gravitational form factor
Zanbin Xing, Minghui Ding, Lei Chang
We provide a novel approach to calculate the gravitational form factor of pion under the ladder approximation of the Bethe-Salpeter equation, with contact interactions. Central to…
Revealing the Signal of QCD Phase Transition in Heavy-Ion Collisions
Yi Lu, Fei Gao, Xiaofeng Luo +2
We propose a novel method to construct the Landau thermodynamic potential directly from the fluctuations measured in heavy-ion collisions. The potential is capable of revealing the…
A symmetry preserving contact interaction treatment of the kaon
Zanbin Xing, Lei Chang
A symmetry-preserving regularization procedure for dealing with the contact interaction model is proposed in this work. This regularization procedure follows a series of consistenc…
Pion scalar, vector and tensor form factors from a contact interaction
Xiaobin Wang, Zanbin Xing, Jiayin Kang +2
The pion scalar, vector and tensor form factors are calculated within a symmetry-preserving contact interaction model (CI) of quantum chromodynamics (QCD), encompassed within a Dys…
Proton and pion distribution functions in counterpoint
Ya Lu, Lei Chang, Khépani Raya +2
Working with proton and pion valence distribution functions (DFs) determined consistently at the same, unique hadron scale and exploiting the possibility that there is an effective…
