Analyses of astrophysical data provide first hints on the self-interactions of dark matter at low
energies. Lattice calculations of dark matter theories can be used to investigate them …

The SU (3) gauge theory with N f= 8 nearly massless Dirac fermions has long been of
theoretical and phenomenological interest due to the near-conformality arising from its …

We provide the first determination of the mass of the lightest flavor-singlet pseudoscalar and
scalar bound states (mesons) in the Sp (4) Yang-Mills theory coupled to two flavors of …

In order to explore the spectrum of hidden-charm scalar and tensor resonances, we study
meson-meson scattering with JPC= 0++, 2++ in the charmonium energy region using lattice …

The effective potential of the O (N) model at large N limit is reinvestigated with varying pion
mass and temperature. For large pion masses and high temperatures, we find the …

Lattice QCD spectra can be used to constrain partial-wave scattering amplitudes that, while
satisfying unitarity, do not have to respect crossing symmetry and analyticity. This becomes a …

Roy-equation analysis on lattice data of π π scattering phase shifts at m π= 391 MeV reveals
that the lowest f 0 meson becomes a bound state under this condition. In addition, there is a …

We collect spectra extracted in the I= ℓ= 1 π π sector provided by various lattice QCD
collaborations and study the m π dependence of ρ-meson properties using Hamiltonian …

Resonance, bound-state, and virtual-state pole positions of the f 0 (500) scalar meson are
computed as a continuous function of pion mass in the framework of a unitarized and …

We derive the integral equations for partial-wave projected three-body scattering
amplitudes, starting from the integral equations for three-body amplitudes developed for …
