Axial vector form factors in Ds to phi semileptonic decays from lattice QCD
Gordon Donald, Christine Davies, Jonna Koponen
We calculate axial vector and vector form factors for the semileptonic decay Ds to phi using HISQ valence quarks on MILC ensembles with 2+1 flavours of asqtad sea quarks. Using twi…
The D to K and D to pi semileptonic decay form factors from Lattice QCD
The HPQCD Collaboration, Jonna Koponen, Christine T. H. Davies +5
We present a new and very high statistics study of D and D_s semileptonic decay form factors on the lattice. We work with MILC N_f=2+1 lattices and use the Highly Improved Staggere…
Staggered fermions, zero modes, and flavor-singlet mesons
Gordon C. Donald, Christine T. H. Davies, Eduardo Follana +1
We examine the taste structure of eigenvectors of the staggered-fermion Dirac operator. We derive a set of conditions on the eigenvectors of modes with small eigenvalues (near-zero…
