We compare several improved actions for staggered quarks. We study the effect of improvement on the taste changing interactions by calculating the splitting in the pion spectrum. We investigate the effect of the improvement on some topological properties.

Quark number susceptibilities approach their ideal gas limit at sufficiently high temperatures. As in the case of other thermodynamic quantities, this limit itself is altered substantially on lattices with small temporal extent, IVt = 4-8, making it thus difficult to check the validity of perturbat

We present preliminary results for the D, meson spectrum and decay constants in unquenched lattice &CD. Simulations are carried out with 2 + 1 dynamical quarks using gauge configurations generated by the MILC collaboration. We use the "asqtad" a2 improved staggered action for the light quarks, and
