Abstract

We show how string breaking on the lattice, treated as a mixing effect, can be related to decay rates for heavy quark systems. We use this to make a preliminary calculation of the energy split at maximum mixing for static quarks in QCD from the decay rate for $Υ(4S)\to B{\bar B}$. We extend the calculation to achieve rough estimates for the contributions of channels involving $B, B^*, B_s and B_s^*$ mesons to the width of the $Υ(5S)$.

Learning Low-Order Approximations of the Quark Propagator in Lattice QCD

The hopping expansion is an important approximation of the quark propagator in lattice quantum chromodynamics, but it diverges for light quarks, which limits the scope of strong-coupling and finite-density simulations. We present an artificial scientific discovery framework using gauge-equivariant neural networks in the Clifford basis to extract interpretable approximations. Our approach yields improved low-order approximations that outperform the hopping expansion at identical computational cost. In the parameter regime where the hopping expansion fails, our approach identifies convergent behavior, thus suggesting a novel series expansion. The discovered approximations generalize to unseen gauge fields and volumes, enabling immediate implementation as plug-in replacements and a new theoretical understanding of quark-propagator expansions.

The sigma meson ($f_0$) at finite temperature with truncated overlap fermions

We study the temperature dependence of meson screening masses in two-flavour lattice QCD using dynamical truncated overlap fermions, a type of lattice chiral fermions. The screening masses for the $π$, $ρ$, $a_1$, $a_0$, and the sigma $(f_0)$ mesons are extracted by computing spatial correlation functions. This exploratory study uses meson screening masses and the connected/disconnected decomposition of the scalar correlator as diagnostic observables to examine how the disconnected contribution changes across the pseudocritical region. Above the pseudocritical temperature $T_{\rm pc}$, the $π$ and $f_0$ screening masses become degenerate, consistent with chiral restoration. The $(ρ,a_1)$ pair also shows the expected degeneracy. Decomposition of the $f_0$ propagator reveals that the connected contribution dominates above $T_{\rm pc}$, while the disconnected part becomes significant below $T_{\rm pc}$, explaining the reduced statistical clarity observed at low $T$. These results demonstrate that dynamical truncated overlap fermion simulations can capture the qualitative thermal behaviour of the scalar sector.

Critical coupling and $Δ\langleϕ^2\rangle$ in three-dimensional $ϕ^4$ theory

We consider the $ϕ^4$ theory with $ϕ(x)\in\mathbb{R}$ in three Euclidean dimensions. For a variety of self-couplings $\hatλ$, the critical (bare) parameter $\hatμ_{0\mathrm{c}}^2(\hatλ)$ is determined where the lattice-regulated system changes from the symmetric phase to the broken phase. Next, we send the box volume to infinity and switch to a universal scheme; this yields $\hatμ_\mathrm{c}^2(\hatλ)$ for each simulated $\hatλ$. Finally, a continuum extrapolation gives $f_\mathrm{c}=\lim_{\hatλ\to0} \hatλ^2/\hatμ_\mathrm{c}^2(\hatλ)$, and we find $f_\mathrm{c} = 18.808(64)_{\mathrm{stat}}(45)_{\mathrm{sys}} = 18.808(78)_{\mathrm{tot}}$. In addition, $Δ\langleϕ^2\rangle_\mathrm{c}/λ= -0.00303(12)_{\mathrm{stat}}(12)_{\mathrm{sys}} = -0.00303(17)_{\mathrm{tot}}$ is determined in the combined continuum and infinite-volume limit.
