Current Projects of the HPQCD Collaboration

$B$ and $\Upsilon$ physics using the Nonrelativistic QCD action for $b$ quarks

Light, charmed and $B$ meson physics using the Highly Improved Staggered Quark action

We work on gluon field configurations that use our improved (through $\alpha_s a^2$) discretisation of the gluon action and include $u$, $d$, $s$ and $c$ quarks in the sea using our Highly Improved Staggered Quark action. These configurations are generated by the MILC collaboration. They include $u$, $d$ sea quarks with a range of masses going down to their physical value for a very realistic picture of the QCD vacuum. We use computer time on the STFC's DiRAC facility and at Fermilab.
