Effects of phase transition in hybrid stars from quark-meson coupling hadronic matter to deconfined quark matter
Yida Yang, Chen Wu, Ji-Feng Yang
Different types of phase transition from hadron to quark at high density near zero temperature may occur in the inner core of hybrid stars. We investigate the impacts of phase tran…
Closed-form Brückner -matrix and nuclear matter in EFT()
Ting-Wei Pan, Ji-Feng Yang
The closed-form Brükner matrix for nuclear matter is computed in the channel of EFT() and renormalized in nonperturbative context. The nuclear medium environ…
Covariant propagator and chiral power counting
Zhou Liu, Li-Hong Wen, J. -F. Yang
Some one-loop diagrams with one and two external baryons/nucleons are revisited using covariant baryon propagators in chiral effective theory. We showed that it is enough to separa…
'Running' under tight constraints in pionless effective field theory
Jun-Jun Lü, Ji-Feng Yang
The contents of renormalization group invariance and equations under tight constraints are explored and demonstrated with closed-form on-shell matrices of pionless effective fi…
Nambu--Jona-Lasinio Model Revisited with a Simple Regularization-Renormalization Method
Guang-jiong Ni, Ji-Feng Yang, Jianjun Xu +1
According to the pioneering model proposed by Nambu and Jona-Lasinio (NJL) \cite{2,3}, a massless fermion acquires its mass via a vacuum phase transition (VPT) process. Our discuss…
Anomalous mapping between pionfull and pionless EFT's
J. -F. Yang
The pion contributions to the coupling of pionless EFT are studied via both non-relativistic and relativistic forms of chiral effective field theory for nuclear forces. A def…
