Lattice QCD matrix elements for the $B_{s}^{0} - B ˉ_{s}^{0}$ width difference beyond leading order

Christine T. H. Davies, Judd Harrison, G. Peter Lepage +3

Predicting the $B_{s}^{0} - B ˉ_{s}^{0}$ width difference $Δ Γ_{s}$ relies on the heavy quark expansion and on hadronic matrix elements of $Δ B = 2$ operators. We present the first lattice QCD…

Neutral B-meson mixing from full lattice QCD at the physical point

R. J. Dowdall, C. T. H. Davies, R. R. Horgan +4

We calculate the bag parameters for neutral $B$ -meson mixing in and beyond the Standard Model, in full four-flavour lattice QCD for the first time. We work on gluon field configura…

Form factor ratios for $B_{s} \to K ℓ ν$ and $B_{s} \to D_{s} ℓ ν$ semileptonic decays and $∣ V_{u b} / V_{c b} ∣$

Christopher J. Monahan, Chris M. Bouchard, G. Peter Lepage +2

We present a lattice quantum chromodynamics determination of the ratio of the scalar and vector form factors for two semileptonic decays of the $B_{s}$ meson: $B_s \rightarrow K \ell…

Improving the theoretical prediction for the $B_{s} - B ˉ_{s}$ width difference: matrix elements of next-to-leading order $Δ B = 2$ operators

Christine Davies, Judd Harrison, G Peter Lepage +3

We present lattice QCD results for the matrix elements of $R_{2}$ and other dimension-7, $Δ B = 2$ operators relevant for calculations of $Δ Γ_{s}$ , the $B_{s} - B ˉ_{s}$ width difference.…
