The long-distance window of the hadronic vacuum polarization for the muon g-2 / RBC Collaboration
We provide the first ab-initio calculation of the Euclidean long-distance window of the isospin symmetric light-quark connected contribution to the hadronic vacuum polarization for the muon g2 and find aLD,iso,conn,udμ=411.4(4.3)(2.4)×1010. [...]

Exclusive semileptonic BsKν decays on the lattice / Flynn, J.M. (Southampton U.) ; Hill, R.C. (Edinburgh U.) ; Jüttner, A. (Southampton U. ; CERN) ; Soni, A. (Brookhaven) ; Tsang, J.T. (CERN) ; Witzel, O. (U. Siegen (main)) /RBC/UKQCD Collaboration
Semileptonic BsKν decays provide an alternative b-decay channel to determine the CKM matrix element |Vub|, and to obtain a R-ratio to investigate lepton-flavor-universality violations. Results for the CKM matrix element may also shed light on the discrepancies seen between analyses of inclusive or exclusive decays. [...]

Detection of a DC Electric Field Using Electro-Optical Crystals / Cristiano, Antonio (CERN ; Huddersfield U.) ; Hill, Richard (Huddersfield U.) ; Krupa, Michal (CERN)
Standard beam position monitors (BPM) are intrinsically insensitive to beams with no temporal structure, so-called DC beams, which many CERN experiments rely on. We therefore propose a novel detection technique in which the usual BPM electrodes are replaced with electro-optic (EO) crystals. [...]

Update of Euclidean windows of the hadronic vacuum polarization / RBC Collaboration
We compute the standard Euclidean window of the hadronic vacuum polarization using multiple independent blinded analyses. We improve the continuum and infinite-volume extrapolations of the dominant quark-connected light-quark isospin-symmetric contribution and address additional sub-leading systematic effects from sea-charm quarks and residual chiral-symmetry breaking from first principles.

Electro-Optic Sensor for Measuring Electrostatic Fields in the Frequency Domain / Cristiano, Antonio (CERN) ; Krupa, Michal (CERN) ; Hill, Richard (Huddersfield U.)
Precise measurements of electrostatic fields in harsh environments are required in fields ranging from particle accelerators to industrial installations. Many techniques disrupt the field distribution due to the presence of conductors. [...]

Pilot-job provisioning on grid resources: Collecting analysis and performance evaluation data / Boyer, Alexandre F (CERN ; Clermont-Ferrand U.) ; Haen, Christophe (CERN) ; Stagni, Federico (CERN) ; Hill, David R C (Clermont-Ferrand U.)
To take advantage of the computing power offered by grid and opportunistic resources, the CERN Large Hadron Collider (LHC) experiments have adopted the Pilot-Job paradigm. In this work, we study the DIRAC Site Director, one of the existing Pilot-Job provisioning solutions, mainly developed and used by the beauty experiment (LHCb). [...]

Lattice quantum chromodynamics has proven to be an indispensable method to determine nonperturbative strong contributions to weak decay processes. [...]

DIRAC Site Director: Improving Pilot-Job provisioning on grid resources / Boyer, Alexandre F (CERN ; U. Clermont Auvergne) ; Haen, Christophe (CERN) ; Stagni, Federico (CERN) ; Hill, David R C (U. Clermont Auvergne)
To study the constituents of matter, CERN mainly relies on the Worldwide LHC Computing Grid (WLCG), which processes petabytes of data coming from the Large Hadron Collider (LHC). LHC experiments have adopted the Pilot-Job paradigm, and deliver tools to supply grid resources with Pilot-Jobs, to efficiently leverage the computing power offered by WLCG. [...]

Simulating rare kaon decays K+π++ using domain wall lattice QCD with physical light quark masses / Boyle, P.A. (Edinburgh U. ; Brookhaven) ; Erben, F. (Edinburgh U.) ; Flynn, J.M. (Southampton U. ; U. Southampton (main)) ; Gülpers, V. (Edinburgh U.) ; Hill, R.C. (Edinburgh U. ; Southampton U.) ; Hodgson, R. (Edinburgh U.) ; Jüttner, A. (Southampton U. ; U. Southampton (main) ; CERN) ; hÓgáin, F.Ó. (Edinburgh U.) ; Portelli, A. (Edinburgh U.) ; Sachrajda, C.T. (Southampton U.) /RBC Collaboration ; UKQCD Collaboration
We report the first calculation using physical light-quark masses of the electromagnetic form factor V(z) describing the long-distance contributions to the K+π++ decay amplitude. The calculation is performed on a 2+1 flavor domain wall fermion ensemble with inverse lattice spacing a1=1.730(4)GeV. [...]
