Description

Using our well established setup of domain-wall light quarks and nonperturbatively tuned, relativistic $b$-quarks we extend our $B$-physics program to the computation of $B$-meson bag parameters and their ratio $\xi$. We present first results based on the RBC/UKQCD 2+1 flavor gauge field configurations with domain-wall fermions and the Iwasaki gauge action at two lattice spacing of 0.086 fm and 0.11 fm.
