Determining the scale in Lattice QCD

V. G. Bornyakov, R. Horsley, R. Hudspith +8

We discuss scale setting in the context of 2+1 dynamical fermion simulations where we approach the physical point in the quark mass plane keeping the average quark mass constant. W…

Lattice QCD on Non-Orientable Manifolds

Simon Mages, Balint C. Toth, Szabolcs Borsanyi +3

A common problem in lattice QCD simulations on the torus is the extremely long autocorrelation time of the topological charge, when one approaches the continuum limit. The reason i…

Applications of the Feynman-Hellmann theorem in hadron structure

A. J. Chambers, R. Horsley, Y. Nakamura +8

The Feynman-Hellmann (FH) relation offers an alternative way of accessing hadronic matrix elements through artificial modifications to the QCD Lagrangian. In particular, a FH-motiv…

Hadronic form factors for rare semileptonic $B$ decays

Jonathan Flynn, Andreas Jüttner, Taichi Kawanai +2

We discuss first results for the computation of short distance contributions to semileptonic form factors for the rare $B$ decays $B \to K^{*} ℓ^{+} ℓ^{-}$ and $B_s \to ϕ\ell^+ \e…

QCD thermodynamics with continuum extrapolated dynamical overlap fermions

Sz. Borsanyi, Z. Fodor S. D. Katz S. Krieg, T. Lippert +4

We study the finite temperature transition in QCD with two flavors of dynamical fermions at a pseudoscalar pion mass of about 350 MeV. We use lattices with temporal extent of $N_{t}$ …

Lattice computation of the nucleon scalar quark contents at the physical point

S. Durr, Z. Fodor, C. Hoelbling +10

We present a QCD calculation of the $u$ , $d$ and $s$ scalar quark contents of nucleons based on $47$ lattice ensembles with $N_{f} = 2 + 1$ dynamical sea quarks, $5$ lattice spacings d…

QED effects in the pseudoscalar meson sector

R. Horsley, Y. Nakamura, H. Perlt +8

We present results on the pseudoscalar meson masses from a fully dynamical simulation of QCD+QED. We concentrate particularly on violations of isospin symmetry. We calculate the $π…

Axion cosmology, lattice QCD and the dilute instanton gas

S. Borsanyi, M. Dierigl, Z. Fodor +6

Axions are one of the most attractive dark matter candidates. The evolution of their number density in the early universe can be determined by calculating the topological susceptib…

Disconnected contributions to the spin of the nucleon

A. J. Chambers, R. Horsley, Y. Nakamura +8

The spin decomposition of the proton is a long-standing topic of much interest in hadronic physics. Lattice QCD has had much success in calculating the connected contributions to t…

Potential description of charmonium and charmed-strange mesons from lattice QCD

Taichi Kawanai, Shoichi Sasaki

We present spin-independent and spin-spin interquark potentials for the charmonium and charmed-strange mesons, which are calculated in 2+1 flavor lattice QCD simulations using the…

Isospin splittings of meson and baryon masses from three-flavor lattice QCD + QED

R. Horsley, Y. Nakamura, H. Perlt +8

Lattice QCD simulations are now reaching a precision where isospin breaking effects become important. Previously, we have developed a program to systematically investigate the patt…

Complex Langevin dynamics for dynamical QCD at nonzero chemical potential: a comparison with multi-parameter reweighting

Z. Fodor, S. D. Katz, D. Sexty +1

We study lattice QCD at non-vanishing chemical potential using the complex Langevin equation. We compare the results with multi-parameter reweighting both from $μ = 0$ and phase quen…

Fluctuations and correlations in high temperature QCD

R. Bellwied, S. Borsanyi, Z. Fodor +4

We calculate second- and fourth-order cumulants of conserved charges in a temperature range stretching from the QCD transition region towards the realm of (resummed) perturbation t…

The QCD phase diagram from analytic continuation

R. Bellwied, S. Borsanyi, Z. Fodor +4

We present the crossover line between the quark gluon plasma and the hadron gas phases for small real chemical potentials. First we determine the effect of imaginary values of the…

The running coupling of the minimal sextet composite Higgs model

Zoltan Fodor, Kieran Holland, Julius Kuti +3

We compute the renormalized running coupling of SU(3) gauge theory coupled to N_f = 2 flavors of massless Dirac fermions in the 2-index-symmetric (sextet) representation. This mode…

High-precision calculation of the strange nucleon electromagnetic form factors

Jeremy Green, Stefan Meinel, Michael Engelhardt +6

We report a direct lattice QCD calculation of the strange nucleon electromagnetic form factors $G_{E}^{s}$ and $G_{M}^{s}$ in the kinematic range $0 \leq Q^{2} ≲ 1.2 GeV^{2}$ . F…
