The Standard Model prediction for the anomalous magnetic moment of the muon, presented in the 2025 White Paper of the Muon g-2 Theory Initiative, is based on consolidated lattice averages for the two leading hadronic contributions, hadronic vacuum polarization and hadronic light-by-light. In this talk, I review the results from lattice QCD+QED calculations that were used in these averages and...
For twenty years, a persistent discrepancy between experimental
measurements and theoretical calculations of the muon anomalous magnetic
moment have provided tantalising hints of new physics. In recent years,
improvements to the experimental precision have appeared to make the
tension stronger and stronger. However, at the same time, our lattice calculation overturned the theoretical...
In recent years, lattice QCD calculations of hadron spectroscopy have concentrated on resonances and shallow bound states detected via poles in two- and three-hadron scattering amplitudes. Hadron interactions have therefore become a key focus. The primary tools for this are finite-volume spectroscopy and finite-volume quantization conditions. I will review the current state of the art and...
Grounding nuclear physics in the Standard Model has been a longstanding goal for many in the lattice QCD community. The combined issues of signal-to-noise and difficulties associated with quantifying multi-hadronic interactions have required enormous efforts and improvements in computational techniques and analysis over the course of decades. Now, we have reached a time when computational and...
I will review the status of lattice QCD in extreme conditions—finite temperature, nonzero baryon chemical potential, and strong magnetic fields. Emphasis will be on the QCD phase structure and bulk thermodyanmics.
We will survey how RHIC and LHC measurements constrain the properties of QCD matter when interpreted with lattice-QCD inputs. The talk will: (i) present hydrodynamic descriptions of momentum and angular distributions using a lattice-anchored equation of state at μB≈0 and its finite-density extensions relevant to the RHIC Beam Energy Scan; (ii) confront fluctuation measurements with lattice...
Dynamical probes such as thermal photons and quarkonia provide valuable insight into the properties of the quark-gluon plasma (QGP) created in heavy-ion collisions. The relevant information is encoded in their spectral functions. Extracting these spectral functions from lattice correlators is a challenging task due to the ill-posed nature of the inverse problem, which requires additional...
Studying the behavior of QCD at high temperatures is essential for understanding the properties of strongly interacting matter and its role in the evolution of the early Universe. A key quantity in this context is the QCD Equation of State. I present a non-perturbative determination with three massless quark flavors, covering a wide range of temperatures, from the electroweak scale down to 3...
I will briefly review how machine learning can be used in lattice gauge theory simulations and what approaches are currently available. I will then dicuss one specific application in more detail, namely the machine learning of RG-improved gauge actions using gauge-equivariant convolutional neural networks. In particular, I will present scaling results for a machine-learned fixed-point action...
I will review the current generation of exascale supercomputers and present performance results for lattice applications. On the software side, I will discuss strategies for achieving performance portability across heterogeneous architectures. I will conclude with an outlook on architectures now under development.
Despite the impressive success of the lattice-gauge-theory program in enabling first-principles predictions in particle, hadronic, and nuclear physics over the years, a range of systems and phenomena will remain out of reach of our current computational paradigm. These include studies of large atomic nuclei and their properties, of phases of matter at finite density, and of the nonequilibrium...
Gauge theories are the cornerstone of our description of nature. At the theoretical level, many of their fascinating aspects - from real time dynamics, to regimes of finite density of baryon matter - represent some of the most notable and fascinating challenges for computational methods. Over the last decade, this has stimulated a broad effort to understand how to quantum simulate gauge...
Many observables used to extract Standard Model parameters and to
constrain New Physics in the quark-flavour sector rely on lattice inputs.
I will review the current status and recent developments in these
determinations, with emphasis on controlling dominant sources of
systematic uncertainties.
I will review recent progress in our understanding of hadron structure, with emphasis on lattice-QCD calculations that directly support the scientific goals of the upcoming Electron-Ion Collider (EIC). I will discuss results for pion, kaon, and proton form factors, the computation of Mellin moments, and recent advances in the direct calculation of generalized parton distributions (GPDs). These...
For decades, the lattice community has successfully extracted fundamental properties of non-abelian gauge theories, like QCD, using the Euclidean path integral formalism and Monte Carlo methods. However, the advent of quantum computation, quantum simulation, and advanced tensor network methods has created new opportunities and demands for a Hamiltonian approach, which is better suited for...
Tensor networks provide novel formulations of lattice field theories, which in turn enable the development of practically efficient renormalization group methods. Unlike conventional Monte Carlo methods, tensor networks are free from the sign problem in principle and can be straightforwardly extended to fermionic systems. We present recent progress in these formulations and numerical...
Special classes of non-supersymmetric, strongly interacting gauge theories provide ultraviolet completions for new physics extensions of the Standard Model that offer potential solutions to key open problems in the energy frontier, including the absence of new physics signatures at energies just above the electroweak scale, the anomalously heavy mass of the top quark, the absence of new flavor...
I review recent progress in calculating scattering amplitudes and resonance properties involving three particles using lattice QCD results for the finite-volume spectrum, coupled with solutions to the associated integral equations. I describe the outlook for future extensions of this work.
