Lattice Results for Low Moments of Light Meson Distribution Amplitudes
Low Moments of Light Meson Distribution Amplitudes
2011/1/14
As part of the UKQCD and RBC collaborations’ Nf = 2+1 domain-wall fermion phenomenology
programme, we calculate the first two moments of the light-cone distribution amplitudes of the
pseudoscalar me...
We describe and test a method known in the literature as low mode averaging to improve Euclidean two-point functions in lattice QCD using the low-lying eigenmodes of the Wilson-Dirac
operator D.
The state of the art in dibaryons with strangeness is reviewed, including the K−pp dibaryon which signals the onset of ¯K –nuclear binding. A new type of strange dibaryons is highlighted, w...
We calculated the first two moments of the light-cone distribution amplitudes for the pseudoscalar mesons (p and K) and the longitudinally polarised vector mesons (r , K∗ and f ) as part of the ...

We perform a non-perturbative lattice calculation of the P-wave pion-pion scattering phase in
the -meson decay channel using two flavors of maximally twisted mass fermions at pion masses
ranging fr...
