FV-type action for AdS(5) mixed-symmetry fields
FV-type action AdS(5) mixed-symmetry fields
2010/12/24
We formulate Fradkin-Vasiliev type theory of massless higher spin fields in AdS(5). The corresponding action functional describes cubic order approximation to gravitational interactions of bosonic mi...
Strangeness in the nucleon from a mixed action calculation
the nucleon mixed action calculation
2011/1/7
The contributions of strange quarks to the nucleon mass and the nucleon spin are investigated in a mixed action scheme employing domain wall valence quarks and quark loops on MILC asqtad dynamical fer...
K --> pi pi matrix elements from mixed action lattice QCD
K --> pi pi matrix elements mixed action lattice QCD
2011/1/7
We present a new method for determining K --> pi pi matrix elements from lattice simulations that is less costly than direct simulations of K --> pi pi at physical kinematics. It improves, however, up...
We report on our simulations with Neuberger valence fermions on CLS $N_f=2$ configurations with non-perturbatively $O(a)$-improved Wilson sea quarks. We consider the matching of QCD to ChPT in the so ...
