Strangeness in lattice QCD [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2001 The status of lattice calculations in the light hadron sector is reviewed. Special emphasis is given to recent lattice determinations of the mass of the strange quark. The impact of non-perturbative renormalization and control over lattice artefacts on the attainable precision is discussed in detail. Furthermore the influence of dynamical quark effects

Master integrals for two-loop QCD corrections to quark quasi PDFs
Journal of High Energy Physics, 2020 We compute the master integrals for the two-loop QCD corrections to quark quasi parton distribution functions (PDFs) in the large momentum effective theory (LaMET). With a proper canonical basis, we derive the analytical results for the three families of

Chiral Fermions Algorithms In Lattice QCD
East European Journal of Physics, 2019 The theory that explains the strong interactions of the elementary particles, as part of the standard model, it is the so-called Quantum Chromodynamics (QCD) theory.

The hadronic vacuum polarization contribution to the muon g − 2 from lattice QCD [PDF]
Journal of High Energy Physics, 2017 We present a calculation of the hadronic vacuum polarization contribution to the muon anomalous magnetic moment, aμhvp, in lattice QCD employing dynamical up and down quarks. We focus on controlling the infrared regime of the vacuum polarization function.

The γπ → ππ anomaly from lattice QCD and dispersion relations
Journal of High Energy Physics, 2021 We propose a formalism to extract the γπ → ππ chiral anomaly F 3π from calculations in lattice QCD performed at larger-than-physical pion masses. To this end, we start from a dispersive representation of the γ (*) π → ππ amplitude, whose main quark-mass ...

High precision renormalization of the flavour non-singlet Noether currents in lattice QCD with Wilson quarks [PDF]
The European Physical Journal C, 2018 We determine the non-perturbatively renormalized axial current for $$\hbox {O}(a)$$O(a) improved lattice QCD with Wilson quarks. Our strategy is based on the chirally rotated Schrödinger functional and can be generalized to other finite (ratios of ...

Excited bottomonia in quark-gluon plasma from lattice QCD
Physics Letters B, 2020 We present the first lattice QCD study of up to 3S and 2P bottomonia at non-zero temperatures. Correlation functions of bottomonia were computed using novel bottomonium operators and a variational technique, within the lattice non-relativistic QCD ...

Results and techniques for higher order calculations within the gradient-flow formalism
Journal of High Energy Physics, 2019 We describe in detail the implementation of a systematic perturbative approach to observables in the QCD gradient-flow formalism. This includes a collection of all relevant Feynman rules of the five-dimensional field theory and the composite operators ...

Determining the nonperturbative Collins-Soper kernel from lattice QCD [PDF]
Physical Review D, 2018 At small transverse momentum $q_T$, transverse-momentum dependent parton distribution functions (TMDPDFs) arise as genuinely nonperturbative objects that describe Drell-Yan like processes in hadron collisions as well as semi-inclusive deep-inelastic ...
