We use the highly-improved staggered quark (HISQ) formulation for the current density with gauge configurations generated with four flavors of HISQ sea quarks. The computation is performed by stochastic estimation of the current density using the truncated solver method combined with deflation of low-modes. The parameters are tuned to minimize the computational cost for a given target uncertainty in the current-current correlation function. The calculation presented here is carried out on a single gauge-field ensemble of size $32^3\times48$ with an approximate lattice spacing of $\sim0.15$ fm and with physical sea-quark masses. We describe the methodology and the analysis procedure en dc.language.iso en en dc.subject hep-lat en dc.subject hep-lat en dc.title Disconnected hadronic vacuum polarization contribution to the muon g-2 with HISQ en dc.type Journal Article plymouth.author-url http://arxiv.org/abs/1811.06058v3 en plymouth.organisational-group /Plymouth plymouth.organisational-group /Plymouth/Faculty of Science and Engineering plymouth.organisational-group /Plymouth/Faculty of Science and Engineering/School of Engineering, Computing and Mathematics plymouth.organisational-group /Plymouth/REF 2021 Researchers by UoA plymouth.organisational-group /Plymouth/REF 2021 Researchers by UoA/UoA10 Mathematical Sciences plymouth.organisational-group /Plymouth/Users by role plymouth.organisational-group /Plymouth/Users by role/Academics dc.rights.embargoperiod Not known en rioxxterms.licenseref.uri http://www.rioxx.net/licenses/all-rights-reserved en rioxxterms.type Journal Article/Review en
