Lattice calculation of the R-ratio smeared with Gaussian kernel
Constantia Alexandrou, Simone Bacchio, Alessandro De Santis +15
The ratio of the cross-sections for hadrons and is a valuable energy-dependent probe of the hadronic sector of the Standard Model. Moreover, t…
Short \& intermediate distance HVP contributions to muon g-2: SM (lattice) prediction versus annihilation data
Constantia Alexandrou, Simone Bacchio, Petros Dimopoulos +13
We present new lattice results of the ETM Collaboration, obtained from extensive simulations of lattice QCD with dynamical up, down, strange and charm quarks at physical mass value…
Time windows of the muon HVP from twisted-mass lattice QCD
C. Alexandrou, S. Bacchio, P. Dimopoulos +13
We present a lattice determination of the leading-order hadronic vacuum polarization (HVP) contribution to the muon anomalous magnetic moment, , in the so-called sho…
Disconnected contribution to the LO HVP term of muon g-2 from ETMC
Constantia Alexandrou, Simone Bacchio, Petros Dimopoulos +13
We present a lattice determination of the disconnected contributions to the leading-order hadronic vacuum polarization (HVP) to the muon anomalous magnetic moment in the so-called…
Twisted mass ensemble generation on GPU machines
Bartosz Kostrzewa, Simone Bacchio, Jacob Finkenrath +4
We present how we ported the Hybrid Monte Carlo implementation in the tmLQCD software suite to GPUs through offloading its most expensive parts to the QUDA library. We discuss our…
Probing the energy-smeared R-ratio on the lattice
Constantia Alexandrou, Simone Bacchio, Alessandro De Santis +15
We present a first-principles lattice QCD investigation of the -ratio between the cross-section into hadrons and that into muons. By using the method of Ref.[1], that a…
Three-body resonances in the theory
Marco Garofalo, Maxim Mai, Fernando Romero-López +2
We study the properties of three-body resonances using a lattice complex scalar theory with two scalars, with parameters chosen such that one heavy particle can decay into th…
Defining Canonical Momenta for Discretised SU(2) Gauge Fields
Marco Garofalo, Tobias Hartung, Karl Jansen +3
In this proceeding contribution we discuss how to define canonical momenta for SU(N) lattice gauge theories in the Hamiltonian formalism in a basis where the gauge field operators…
Lattice calculation of the short and intermediate time-distance hadronic vacuum polarization contributions to the muon magnetic moment using twisted-mass fermions
C. Alexandrou, S. Bacchio, P. Dimopoulos +13
We present a lattice determination of the leading-order hadronic vacuum polarization (HVP) contribution to the muon anomalous magnetic moment, , in the so-called sho…
