Abstract In this article, we reexamine the mass spectrum of the ground state triply heavy baryon states with the QCD sum rules by carrying out the operator product expansion up to the vacuum condensates of dimension 6 in a consistent way and preformi

Heavy baryons with strangeness in a soliton model

Autor: J.P. Blanckenberg, H. Weigel

Publikováno v: Physics Letters B, Vol 750, Iss C, Pp 230-236 (2015)

We present results from a chiral soliton model calculation for the spectrum of baryons with a single heavy quark (charm or bottom) and non-zero strangeness. We treat the strange components within a three flavor collective coordinate quantization of t

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

Diffusion nucléon-nucléon dans la théorie des champs effective chirale covariante

Autor: Xiao, Yang

Studying nuclear structure and nuclear reactions based on the microscopic nuclear forces has been a central topic in nuclear physics since its inception. However, tricky puzzles rooted in conventional microscopic nuclear forces --- for example, the n
