Description

We report a state-of-the-art lattice QCD calculation of the isovector quark transversity distribution of the proton in the continuum and physical limit using large-momentum effective theory. The calculation is done at three lattice spacings $a \approx$ {0.085, 0.064, 0.049} fm and various pion masses $m_{\pi} \approx$ {350, 280, 220} MeV, with the proton momenta up to 2.8 GeV. The result is non-perturbatively renormalized in the hybrid scheme with self renormalization which is the only infrared-free approach known so far, and extrapolated to the continuum, physical and infinite momentum limit. We also make a comparison with recent global analyses for the nucleon isovector quark transversity distribution.
