We present the first lattice QCD calculation of the $B_s$ and $B_d$ mixingparameters with physical light quark masses. We use MILC gluon fieldconfigurations that include $u$, $d$, $s$ and $c$ sea quarks at 3 values of thelattice spacing and with 3 values of the $u/d$ quark mass going down to thephysical value. We use improved NRQCD for the valence $b$ quarks. Preliminaryresults show significant improvements over earlier values.
