Flavour physics is an important area of phenomenology for performing tests of the Standard Model and searching for new physics using the rich category of decays available. These pursuits require high-precision theoretical predictions to compare to experiment, where lattice QCD has been instrumental in driving the precision of many processes. I will first give a short overview of the...

I will review recent advances in the direct study of three-hadron interactions from lattice QCD. Building on the pioneering work of Lüscher, many lattice QCD calculations to date have employed mathematical relations connecting finite-volume energies and matrix elements to physical scattering and decay amplitudes. While applications to two-hadron channels are well established, those to three-...

We discuss the calculation of the inclusive semileptonic decay for the process $B_s \to X_c l \nu_l$ using lattice QCD. Such a calculation could be decisive in understanding the CKM matrix puzzle: the long-standing tension between inclusive and exclusive determinations of the CKM matrix element, $|V_{cb}|$. A key quantity in these inclusive decays is the four-point correlation function. In...

Recent numerical results have provided evidence for a conjectured regime of finite temperature QCD where chiral symmetry remains unbroken but the system still confines. Moreover, it has been shown that observables constructed from non-perturbative excitations of the Yang-Mills vacuum, namely monopoles and vortices, can be highly sensitive to the deconfinement transition in pure...

Center vortices are often portrayed as objects which cause confinement. I will demonstrate that this is not necessarily true, and that they play a central role in causing a photon to emerge.

Hamiltonian Truncation provides a non-perturbative approach to quantum field theory in which one starts from a solvable theory, constructs its Hilbert space, and restricts to a finite-dimensional subspace of states below an energy cutoff $E_\text{max}$ . Within this truncated space, the target Hamiltonian is approximated and studied. In this talk I will introduce this framework (distinguishing...

Simulating lattice gauge theories on quantum computers presents unique challenges driving the development of novel theoretical frameworks. The orbifold lattice formulation offers a scalable framework for quantum simulations of lattice gauge theories. The corresponding quantum circuits can be constructed explicitly, and the computational cost grows polynomially with the number of qubits....

The general simulation of Quantum Field Theory scales exponentially with the spatial volume, which makes the sizable computation possible only through the quantum computer. The standard quantum algorithm for the scalar field theory has long been developed, where the scalar field is simple enough to admit an obviously optimal qubit approximation to the continuum theory. When extending to the...

In the study of cosmological phase transitions, even apparently weakly coupled theories develop strongly coupled sectors. For static equilibrium quantities, lattice and effective field theory methods have been developed to tackle this which are able to yield unambiguously correct results up to small errors. For real-time quantities, the problem is more complicated. In this talk, I will review...

Non-supersymmetric strongly interacting gauge theories can provide ultraviolet completions of the Higgs sector of the Standard Model that address several outstanding problems at the energy frontier of particle physics: the absence of new particle discoveries across a wide energy range above the electroweak scale, the proximity of the top quark mass to the electroweak scale, and the nature of...

As a fully computational discipline, the quality of lattice research depends heavily on the quality of its underpinning software—including the correctness of the implementation, the ease of modification, and the speed at which it can generate results. All of these aspects can be improved both by the involvement of dedicated Research Software Engineers, and by the application of Research...
