Consistency between SU(3) and SU(2) covariant baryon chiral perturbation theory for the nucleon mass
Publikováno v:
Physics Letters B, Vol 766, Iss C, Pp 325-333 (2017)
Treating the strange quark mass as a heavy scale compared to the light quark mass, we perform a matching of the nucleon mass in the SU(3) sector to the two-flavor case in covariant baryon chiral perturbation theory. The validity of the 19 low-energy

In the past, the axion-nucleon coupling has been calculated in the framework of SU(2) heavy baryon chiral perturbation theory up to third order in the chiral power counting. Here, we extend these earlier studies to the case of heavy baryon chiral per

The pseudoscalar current-delta transition form factors are calculated in the framework of relativistic baryon chiral perturbation theory including order $\mathcal{O} q^4 $. The complex-mass scheme, which is suitable and well-defined for unstable part

We construct a relativistic chiral nucleon-nucleon interaction up to the next-to-next-to-leading order in covariant baryon chiral perturbation theory. We show that a good description of the $np$ phase shifts up to $T_\mathrm{lab}=200$ MeV and even hi

We calculate the nonperturbative two-pion exchange (TPE) contributions to the $NN$ interaction in covariant baryon chiral perturbation theory. We study how the nonperturbative resummation affects the $NN$ phase shifts for partial waves with $J \geq 3

The baryon axial vector current is computed in heavy baryon chiral perturbation theory in the large-${N}_{c}$ limit, where ${N}_{c}$ is the number of color charges. One-loop nonanalytic corrections of the order ${m}_{q}\mathrm{ln}{m}_{q}$ are compris

In this work, we explore the predictive power of the recently proposed covariant chiral nuclear force. In particular, we focus on the $^3S_1$-$^3D_1$ coupled channel and show that it is capable to predict the $^3D_1$ phase shifts and mixing angle $\v

We have systematically investigated the magnetic moments of spin-$\frac{1}{2}$ doubly charmed baryons in the framework of the heavy baryon chiral perturbation theory. In this paper, one loop corrections with intermediate spin-$\frac{1}{2}$ and spin-$
