There has been recent, significant, advances in the determination of the hadron spectrum. Current efforts have focused on the development and application of finite-volume formalisms that allow for the determination of scattering amplitudes as well as resonance behavior in coupled channel systems. I will review some of these recent developments and outline future directions of research.
BESIII is an experiment running at tau-charm energy region at the Beijing Electron Positron Collider (BEPCII). Since the first data taking in 2009, BESIII has accumulated the world's largest data samples of $D$ and $D_s$ meson decays, 10 billion $J/\psi$ and 450 million $\psi(3686)$ events, and about 100 million events with center-of-mass energy between 4 and 4.6 GeV for studies of nonstandard...
Heavy flavor exotic hadrons, and in particular tetraquarks, continue to challenge our understanding and elude explanation from theory. In this contribution we discuss and review the progress and status in studying doubly heavy tetraquark states with $J^P=1^+$ on the lattice. In particular, we focus on our recent efforts using 2+1 flavor lattice QCD with pion masses of 164, 299 and 415 MeV at...
Lattice QCD is an important tool for theoretical input for flavor physics. There have been four reviews by the Flavour Lattice Averaging Group (FLAG). This talk will review the current status of the magnitude of eight of the nine CKM matrix elements, borrowing heavily from the most recent FLAG review (co-authored by the speaker). Future prospects for improving the determination of the CKM...
We consider a novel approach of calculating inclusive neutrino-nucleon scattering cross sections at low energies via the hadronic tensor on the lattice. This is relevant to the neutrino-nucleus scattering experiments such as DUNE at Fermilab. All the elastic, resonance, shallow and deep inelastic contributions can be covered. The inverse problem encountered in the calculation and several...
Because of the severe sign problem afflicting lattice QCD at finite
baryon density, still little is known from first principles about the
phase diagram as a function of temperature and baryon chemical potential.
In order to understand its relation
to the underlying symmetries, it is necessary to study QCD in a wider
parameter space with varying
numbers of flavours and quark masses and, in...
Heavy quarks and heavy-flavor mesons are essential probes to investigate quark-gluon plasma produced in ultra-relativistic heavy ion collisions. On the other hand, extracting spectral properties from lattice heavy-flavor correlation functions to understand dissociation patterns of the bound states and heavy quark transport is a challenging subject in lattice QCD. In this talk, recent progress...
I will discuss progress in lattice calculations of $B \to D^* \ell v$ form factors, and related decays involving a $b \to c$ transition. These are important for the precision determination of $|V_{cb}|$ in the Standard Model (SM), and a possible key to resolving long-standing discrepancy between inclusive and exclusive determinations. I will also discuss their relevance for understanding the...
The large-moment effective theory (LaMET) is a systematic approach to extract light-cone parton distributions from equal-time matrix elements, or quasi parton distributions, that are calculable in lattice QCD. Recent years have seen rapid developments in the LaMET approach which have been applied to various lattice calculations and led to much promising progress in this field. In this talk, I...
I will review the latest developments in lattice computations of the x-dependent parton structure of hadrons using quasi-PDF, pseudo-PDF, good lattice cross-section approach as well as using the moments of PDF. I will also focus on the practical aspects of LaMET approach such as the validity of 1-loop perturbative matching, control of the excited states of boosted hadrons and the different...
Electron Ion Collider (EIC), regarded as the ”super electron microscope”, can provide the clearest image inside of the nucleon. It is the most ideal tool to understand the internal structure of the nuclear matter, especially the quark-gluon structure of the nucleon and nuclei. Polarized EICs are the next generation ”multi-dimensional electron microscopes” that are most effective in studying...
I will review recent lattice calculations of nucleon structure and matrix elements between nucleons.
The past ten years has seen GPUs evolve from a niche architecture to the de facto parallel computing platform in HPC. We report on the latest developments in the use of GPUs for lattice field theory computations, with focus on algorithmic and scaling work by the community.
One of the most promising quantities for the search of signatures of physics beyond the Standard Model is the anomalous magnetic moment g-2 of the muon, where a comparison of the experimental result with the Standard Model estimate yields a deviation of about 3.5 sigma. On the theory side, the largest uncertainty arises from the hadronic sector, namely the hadronic vacuum polarisation and the...
Measurement of the muon anomalous magnetic moment (muon g-2) is a sensitive tool for testing the Standard Model (SM) and searching for new physics. It is an important and complementary tool to probe the high energy frontier. In this talk, I will provide an overview on the Fermilab Muon g-2 experiment, which aims to perform the measurement the muon g-2 with a precision goal of 140 parts per...
Lattice gauge theory studies of hadron-hadron interactions, hadron interactions with electroweak and beyond the Standard Model currents, and the structure of interacting multi-hadron systems, are providing qualitative insights into the dynamics of quarks and gluons as well as quantitative predictions for high-energy colliders, medium-energy neutrino experiments, low-energy searches for...
I will present recent progress of baryon-baryon interaction from lattice QCD. So far, there are two methods to study the interaction: The direct method based on Luscher's finite volume formula which extracts eigen energies from the plateaux of the temporal correlation functions and the HAL QCD method which extracts observables from the non-local potential associated with the tempo-spatial...
In recent years, the finite-volume Lüscher formalism has become a well-established
tool to study the two-body scattering processes on the lattice. The formalism has been
generalized to the case of the coupled two-body channels and has been successfully
applied for the analysis of the lattice data for different scattering processes. A closely
related method, known under the name of the...
Strongly coupled gauge theories can be used in various context to build models that addresses some of the issues of the Standard Model. After reviewing the various scenarios of electroweak symmetry breaking models based on new strongly interacting sector, I will present the variety of challenges they offer to the lattice community. I will then review the on-going lattice efforts to explore...
I will review recent progress on addressing large N gauge theories on the lattice. The focus will be put on the use of volume independence as a tool to tackle otherwise unreachable large number of colours. Future prospects and challenges for the study of large N QCD and various extensions will also be discussed.
The properties of dense QCD matter are delineated through the construction of equations of state which should be consistent with QCD calculations in the low and high density limits, nuclear laboratory experiments, and the neutron star observations. These constraints, together with the causality condition of the sound velocity, are used to develop the picture of hadron-quark continuity in which...
The zeta-regularization allows to establish a
connection between Feynman’s path
integral and Fourier integral operator
zeta-functions. This fact can be utilized to perform a
regularization of vacuum expectation values in quantum field theories.
In this talk, we will describe the concept of this
zeta-regularization, give a simple example and demonstrate
that quantum computing can be employed to...
