The first moment of the Kaon distribution amplitude
from Nf = 2+1 Domain Wall Fermions
The first moment of the Kaon distribution amplitude
from Nf = 2+1 Domain Wall Fermions
We present a lattice computation of the first moment of the kaon’s leading-twist distribution amplitude.
We use ensembles with 2+1 dynamical flavours of domain wall fermions and the Iwasaki
gauge action from the RBC and UKQCD joint dataset. We observe the expected chiral behaviour
and obtain hx i(2GeV) ? 3/5a1
K (2GeV) = 0.032(3), which agrees very well with other results
obtained using QCD sum-rules and the recent lattice result from the UKQCD/QCDSF collaboration.

Abstract
We present a lattice computation of the first moment of the kaon’s leading-twist distribution amplitude.
We use ensembles with 2+1 dynamical flavours of domain wall fermions and the Iwasaki
gauge action from the RBC and UKQCD joint dataset. We observe the expected chiral behaviour
and obtain hx i(2GeV) ? 3/5a1
K (2GeV) = 0.032(3), which agrees very well with other results
obtained using QCD sum-rules and the recent lattice result from the UKQCD/QCDSF collaboration.
