Third moments of nucleon unpolarized, polarized, and transversity parton distribution functions from physical-point lattice QCD

Emilio Taggi, Michael Engelhardt, Jeremy R. Green +6

Using forward matrix elements of local leading-twist operators, we present a determination of the isovector third Mellin moments $⟨ x^{2} ⟩$ of nucleon unpolarized, polari…

$Ξ_{c} \to Ξ$ form factors from lattice QCD with domain-wall quarks: A new piece in the puzzle of $Ξ_{c}^{0}$ decay rates

Callum Farrell, Stefan Meinel

We present a lattice-QCD determination of the vector and axial-vector form factors that describe the charm-baryon semileptonic decays $Ξ_{c} \to Ξ ℓ^{+} ν_{ℓ}$ . The calculation uses…

$B \to I ¨ ℓ I^ˉ ½$ resonance form factors from $B \to I ¨ I ¨ ℓ I^ˉ ½$ in lattice QCD

Luka Leskovec, Stefan Meinel, Marcus Petschlies +3

The decay $B \to I ¨ ℓ I^ˉ ½$ is an attractive process for determining the magnitude of the smallest CKM matrix element, $∣ V_{u b} ∣$ , and can provide new insights into the origin…
