Unquenched determination of the kaon parameter B_K from improved staggered fermions
E. Gamiz, S. Collins, C. T. H. Davies +3
The use of improved staggered actions (HYP, Asqtad) has been proved to reduce the scaling corrections that affected previous calculations of B_K with unimproved (standard) staggere…
Dynamical determination of B_K from improved staggered quarks
E. Gamiz, S. Collins, C. T. H. Davies +2
The scaling corrections that affected previous staggered calculations of B_K have been proved to be reduced by using improved actions (HYP, Asqtad) in the quenched approximation. T…
A nonperturbative determination of cA
S. Collins, C. T. H. Davies
We describe a non-perturbative determination of using correlators containing the axial-vector and pseudoscalar currents at zero and non-zero momentum. We apply the method of…
B Meson Decay Constants From NRQCD
A. Ali Khan, T. Bhattacharya, S. Collins +5
We present quenched results for B meson decay constants using NRQCD b quarks and O(a) tadpole improved clover light quarks. For the first time, one-loop matching factors between la…
From Spectroscopy to the Strong Coupling Constant with Heavy Wilson Quarks
M. Wingate, T. DeGrand, S. Collins +1
In this work we present lattice calculations of the masses of P-wave mesons using Monte Carlo simulations. Our valence fermions are defined by the Wilson action. Our gauge fields a…
Quenched results on Mesons with NRQCD
A. Ali Khan, S. Collins, C. T. H. Davies +3
Preliminary results on spectrum and decay constant of mesons from a quenched simulation at on an lattice are discussed. The heavy quark has been impleme…
P-wave meson properties with Wilson quarks
M. Wingate, T. DeGrand, S. Collins +1
We describe two calculations involving P-wave mesons made of Wilson quarks: the strong coupling constant in the presence of two flavors of light dynamical fermions and the ma…
