QCD in the chiral SU(3) limit from baryon masses on Lattice QCD ensembles
Matthias F. M. Lutz, Yonggoo Heo, Renwick J. Hudspith
The baryon masses on CLS ensembles are used to determine the LEC that characterize QCD in the flavor-SU(3) limit with vanishing up, down, and strange quark masses. Here we reevalua…
Triangle and box diagrams in coupled-channel systems from the chiral Lagrangian
Tobias Isken, Xiao-Yu Guo, Yonggoo Heo +2
We perform an analysis of triangle- and box-loop contributions to the generalized potential in the scattering of Goldstone bosons off the J^P= 0^- and 1^- charmed mesons. Particula…
Low-energy constants in the chiral Lagrangian with baryon octet and decuplet fields from Lattice QCD data on CLS ensembles
Matthias F. M. Lutz, Yonggoo Heo, Xiao-Yu Guo
We perform an analysis of Lattice QCD data on baryon octet and decuplet masses based on the chiral SU(3) Lagrangian. Low-energy constants (LEC) are adjusted to describe baryon mass…
From lattice QCD to predictions of scattering phase shifts at the physical point
Xiao-Yu Guo, Yonggoo Heo, Matthias F. M. Lutz
The Hadron Spectrum Collaboration (HSC) presented new results on two of their ensembles for s-wave scattering phase shifts in the open-charm sector of QCD. For such ensembles we ha…
Constraints from a large-N_c analysis on meson-baryon interactions at chiral order Q^3
Yonggoo Heo, C. Kobdaj, M. F. M. Lutz
We consider the chiral Lagrangian for baryon fields with J^P =\frac{1}{2}^+ or J^P =\frac{3}{2}^+ quantum numbers as constructed from QCD with up, down and strange quarks. The spec…
On a first order transition in QCD with up, down and strange quarks
Xiao-Yu Guo, Yonggoo Heo, Matthias F. M. Lutz
We consider the quark-mass dependence of the baryon octet and decuplet ground state masses. It is predicted that QCD dynamics implies a first order transition when increasing the s…
