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…
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…
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…
A generalized Higgs potential with two degenerate minima for a dark QCD matter scenario
Matthias F. M. Lutz, Yonggoo Heo, Xiao-Yu Guo
We consider the Higgs potential in generalizations of the Standard Model. The possibility of the potential to develop two almost degenerate minima is explored. This would imply tha…
Low-energy constants from charmed baryons on QCD lattices
Yonggoo Heo, Xiao-Yu Guo, Matthias F. M. Lutz
We study the light quark-mass dependence of charmed baryon masses as measured by various QCD lattice collaborations. A global fit to such data based on the chiral SU(3) Lagrangian…
On the convergence of chiral expansions for charmed meson masses in the up, down and strange quark masses
Matthias F. M. Lutz, Xiao-Yu Guo, Yonggoo Heo
We discuss the convergence properties of chiral expansions for the pseudoscalar and vector charmed meson masses based on the chiral SU(3) Lagrangian. Conventional expansion strateg…
