Improved analysis of strong-interaction-stable doubly-bottom tetraquarks on the lattice

B. Colquhoun, A. Francis, R. J. Hudspith +3

We update earlier lattice results for the binding energies of the flavor antitriplet of strong-interaction-stable doubly bottom, $J^{P} = 1^{+}$ tetraquarks, employing an extended sink c…

The search for new physics in $B \to K ℓ^{+} ℓ^{-}$ and $B \to K ν ν ˉ$ using precise lattice QCD form factors

W. G. Parrott, C. Bouchard, C. T. H. Davies

We present HPQCD's improved scalar, vector and tensor form factors for $B \to K$ semileptonic decays, using the heavy-HISQ formalism for more accurate normalisation of the weak cur…

Standard Model predictions for $B \to K ℓ^{+} ℓ^{-}$ , $B \to K ℓ_{1}^{-} ℓ_{2}^{+}$ and $B \to K ν ν ˉ$ using form factors from $N_{f} = 2 + 1 + 1$ lattice QCD

W. G. Parrott, C. Bouchard, C. T. H. Davies

We use HPQCD's recent lattice QCD determination of $B \to K$ scalar, vector and tensor form factors to determine Standard Model differential branching fractions for $B \to K \ell^+…

$V_{cs}$ determination from $D \to K ℓ ν$

W. G. Parrott, Bipasha Chakraborty, C. Bouchard +3

Semileptonic $D \to K ℓ ν$ decays provide one angle of attack to get at the CKM matrix element $V_{cs}$ , complementary to the study of leptonic $D_{s}$ decays. Here, HPQCD presen…

Improved $V_{cs}$ determination using precise lattice QCD form factors for $D \to K ℓ ν$

Bipasha Chakraborty, W. G. Parrott, C. Bouchard +3

We provide a 0.8\%-accurate determination of $V_{cs}$ from combining experimental results for the differential rate of $D \to K$ semileptonic decays with precise form facto…
