Generalized boost transformations in finite volumes and application to Hamiltonian methods
Yan Li, Jia-Jun Wu, T. -S. H. Lee +1
The investigation of hadron interactions within lattice QCD has been facilitated by the well-known quantisation condition, linking scattering phase shifts to finite-volume energies…
Study of the pion-mass dependence of -meson properties in lattice QCD
Kang Yu, Yan Li, Jia-Jun Wu +2
We collect spectra extracted in the sector provided by various lattice QCD collaborations and study the dependence of -meson properties using Hamiltonian E…
Towards high partial waves in lattice QCD with a dumbbell-like operator
Jia-Jun Wu, Waseem Kamleh, Derek B. Leinweber +4
An extended two-hadron operator is developed to extract the spectra of irreducible representations (irreps) in the finite volume. The irreps of the group for the finite volume syst…
Hamiltonian effective field theory in elongated or moving finite volume
Yan Li, Jia-jun Wu, Derek B. Leinweber +1
We extend previous work concerning rest-frame partial-wave mixing in Hamiltonian effective field theory to both elongated and moving systems, where two particles are in a periodic…
Partial Wave Mixing in Hamiltonian Effective Field Theory
Yan Li, Jia-jun Wu, Curtis D. Abell +2
We explore partial-wave mixing in the finite volume based on HEFT, and provide the P-Matrix to show the degree of partial-wave mixing. An example of isospin-2 scattering is us…
Partial Wave Mixing in Hamiltonian Effective Field Theory
Yan Li, Jia-jun Wu, Curtis D. Abell +2
Within general partial-wave mixing, a method for reducing the high dimension of the finite-volume Hamiltonian from Hamiltonian effective field theory is proposed. This method provi…
Partial Wave Mixing in Hamiltonian Effective Field Theory
Yan Li, Jia-Jun Wu, Curtis D. Abell +2
The spectrum of excited states observed in the finite volume of lattice QCD is governed by the discrete symmetries of the cubic group. This finite group permits the mixing of orbit…
