We have performed the first n f = 2 + 1 + 1 lattice QCD computations of the properties (masses and decay constants) of ground-state charmonium mesons. Our calculation uses the HISQ action to generate quark-line connected two-point correlation functions on MILC gluon field configurations that include u / d quark masses going down to the physical point, tuning the c quark mass from M J / ψ and including the effect of the c quark’s electric charge through quenched QED…

Standard Model predictions for $B\to K\ell^+\ell^-$, $B\to K\ell_1^- \ell_2^+$ and $B\to K\nu\bar{\nu}$ using form factors from $N_f=2+1+1$ lattice QCD

We use HPQCD’s recent lattice QCD determination of B → K scalar, vector and tensor form factors to determine Standard Model differential branching fractions for B → K(cid:96) + (cid:96) − , B →

Indirect constraints on lepton-flavour-violating quarkonium decays

Within an effective-field-theory framework, we present a model-independent analysis of the potential of discovering new physics by searching for lepton flavour violation in heavy quarkonium decays

Optimizing creation operators for charmonium spectroscopy on the lattice

Smearing the bare quantum fields in lattice calculations before applying composite hadron creation operators has a long record of substantially improving overlaps onto low-lying energy eigenstates. A

Properties of low-lying charmonia and bottomonia from lattice QCD + QED

The precision of lattice QCD calculations has been steadily improving for some time and is now approaching, or has surpassed, the 1% level for multiple quantities. At this level QED effects, i.e. the

We report initial results from our study of the masses and decay constants of the lightest multiplet of charmonium-like hybrid mesons. We obtain precise measurements of the 1−+ state through the use
