$π γ \to π π$ transition and the $ρ$ radiative decay width from lattice QCD

Journal Article Alexandrou, Constantia ; Leskovec, Luka ; Meinel, Stefan ; ... - Physical Review D

In this paper, we report a lattice QCD determination of the πγ → ππ transition amplitude for the P-wave, I = 1 two-pion final state, as a function of the photon virtuality and ππ invariant mass. The calculation was performed with 2 + 1 flavors of clover fermions at a pion mass of approximately 320 MeV, on a 32 ³ × 96 lattice with L ≈ 3.6 fm. We construct the necessary correlation functions using a combination of smeared forward, sequential and stochastic propagators, and determine the finite-volume matrix elements for all ππ momenta up to |more »« less

Proton Isovector Helicity Distribution on the Lattice at Physical Pion Mass

Journal Article Lin, Huey-Wen ; Chen, Jiunn-Wei ; Ji, Xiangdong ; ... - Physical Review Letters

We present a state-of-the-art calculation of the isovector quark helicity Bjorken-x distribution in the proton using lattice-QCD ensembles at the physical pion mass. We compute quasi-distributions at proton momenta P _z ϵ {2.2; 2.6; 3.0} GeV on the lattice, and match them systematically to the physical parton distribution using large-momentum effective theory (LaMET).We reach an unprecedented precision through high statistics in simulations, large-momentum proton matrix elements, and control of excited-state contamination. The resulting distribution with combined statistical and systematic errors is in agreement with the latest phenomenological analysis of the spin-dependent experimental data; in particular, Δmore » $$\bar{u}$$(x) > Δ$$\bar{d}$$(x).« less

Kaon distribution amplitude from lattice QCD and the flavor SU(3) symmetry

Journal Article Zhang, Rui ; Chen, Jiunn -Wei ; Jin, Luchang ; ... - Nuclear Physics. B

We present the first lattice-QCD calculation of the kaon distribution amplitude using the large-momentum effective theory (LaMET) approach. The momentum-smearing technique has been implemented to improve signals at large meson momenta. We subtract the power divergence due to Wilson line to high precision using multiple lattice spacings. The kaon structure clearly shows an asymmetry of the distribution amplitude around x = 1/2, a clear sign of its skewness. Our result also prefers a broader distribution than the asymptotic form. We also study the leading SU(3) flavor symmetry breaking relations for the pion, kaon and eta meson distribution amplitudes, and themore »« less
