Pion axioproduction revisited

Cheng-Cheng Li, Tao-Ran Hu, Feng-Kun Guo +1

In this work, we extend the analysis of the pion axioproduction, $a N \to I ¨ N$ , to include the impact of the Roper resonance $N^{*} (1440)$ together the previously studied $I^ (1232)$ …

Renormalization of chiral perturbation theory with spinless matter field in curved spacetime

Cheng-Cheng Li, Xiong-Hui Cao, Feng-Kun Guo

We generalize chiral perturbation theory with spinless matter fields in the fundamental representation of $SU (N)$ to curved spacetime in the presence of an external gravitati…
