Developments in Finite Temperature QCD on the Lattice with Dynamical Quarks [PDF]
, 1997 I report on some recent developments in nonperturbative studies of finite temperature QCD with dynamical quarks on the lattice. I discuss new studies of improved lattice actions and their application to finite temperature QCD. I also summarize the status

Lattice QCD investigation of a doubly-bottom b¯b¯ud tetraquark with quantum numbers I(JP)=0(1+) [PDF]
Physical Review D, 2019 We use lattice QCD to investigate the spectrum of the $\bar{b} \bar{b} u d$ four-quark system with quantum numbers $I(J^P) = 0(1^+)$. We use five different gauge-link ensembles with $2+1$ flavors of domain-wall fermions, including one at the physical ...

Inclusive Semileptonic Decays from Lattice QCD. [PDF]
Physical Review Letters, 2020 We develop a method to compute the inclusive semileptonic decay rate of hadrons fully nonperturbatively using lattice QCD simulations. The sum over all possible final states is achieved by a calculation of the forward-scattering matrix elements on the ...

Lattice analysis for the energy scale of QCD phenomena [PDF]
, 2008 We formulate a new framework in lattice QCD to study the relevant energy scale of QCD phenomena. By considering the Fourier transformation of link variable, we can investigate the intrinsic energy scale of a physical quantity nonperturbatively.

Nuclear Physics B - Proceedings Supplements, 1995 We show that the perturbatively-improved gluon action for QCD, once it is tadpole-improved, gives accurate results even with lattice spacings as large as 0.4~fm. {\em No\/} tuning of the couplings is required. Using this action and lattice spacing, we obtain a static potential that is rotationally invariant to within a few percent, the spin-averaged ...

Odd-spin glueballs, AdS/QCD and information entropy
Physics Letters B, 2020 Odd-spin glueballs in the dynamical AdS/QCD model are scrutinized, in the paradigm of the configurational entropy (CE). Configurational-entropic Regge trajectories, that relate the CE underlying odd-spin glueballs to their mass spectra and spin, are then

Vacuum correlators at short distances from lattice QCD
Journal of High Energy Physics, 2021 Non-perturbatively computing the hadronic vacuum polarization at large photon virtualities and making contact with perturbation theory enables a precision determination of the electromagnetic coupling at the Z pole, which enters global electroweak fits ...

First Evidence of $N_f$-Dependence in the QCD Interquark Potential [PDF]
, 1996 We present a lattice calculation of the interquark potential between static quarks in a ``full'' QCD simulation with 2 flavours of dynamical Wilson-quarks at three intermediate sea-quark masses. We work at $\beta = 5.6$ on lattice size of $16^3 \times 32$

Heavy-hadron interactions from Lattice QCD
EPJ Web of Conferences, 2018 I review recent progress in heavy hadron spectroscopy and from ab-initio Lattice QCD calculations.After motivating lattice calculations for heavy-hadrons by contrasting recent LHCb results charmed and doubly-charmed baryons with lattice predictions ...

QCD chiral Lagrangian on the lattice, strong coupling expansion and Ward identities with Wilson fermions [PDF]
, 1996 We discuss a general strategy to compute the coefficients of the QCD chiral Lagrangian using lattice QCD with Wilson fermions. This procedure requires the introduction of a lattice chiral Lagrangian as an intermediate step in the calculation.
