abstract
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 proximity to the conformal window. One particularly interesting feature is the emergence of a relatively light, stable flavor-singlet scalar meson $\sigma$ $(J^{PC}=0^{++})$ in contrast to the $N_f=2$ theory QCD. In this work, we study the finite-volume dependence of the $\sigma$ meson correlation function computed in lattice gauge theory and determine the $\sigma$ meson mass and decay constant extrapolated to the infinite-volume limit. We also determine the infinite volume mass and decay constant of the flavor-nonsinglet scalar meson $a_0$.

Dilaton Physics from Asymptotic Freedom
In a large-N 3D Gross-Neveu-Yukawa theory, the endpoint of the conformal window spontaneously breaks scale symmetry, producing a massless dilaton whose decay constant and induced mass obey a universal product formula.

Investigating SU(3) with Nf=8 fundamental fermions at strong renormalized coupling
Finite-size scaling of lattice data favors a merged fixed point governing the strong-to-weak coupling transition in SU(3) with eight fundamental flavors, suggesting this system sits at the opening of the conformal window.

Naturally resonant two-mediator model of self-interacting dark matter with decoupled relic abundance
A two-mediator dark matter model with a near-threshold heavy resonance reconciles relic abundance with self-interactions, but a unit conversion error inflates its direct detection signal by a factor of 1000.
