| dc.description | We present an unquenched lattice calculation for the SU(3) flavor breaking ratios of the heavy-light decay constants and the $ΔB = 2$ matrix elements. The calculation was performed on $16^3 \times 32$ lattices with two dynamical flavors of domain-wall quarks and inverse lattice spacing $1/a = 1.69(5)$ GeV. Heavy quarks were implemented using an improved lattice formulation of the static approximation. In the infinite heavy-quark mass limit we obtain $f_{B_s}/f_{B_d} = 1.29(4)(6)$, $B_{B_s}/B_{B_d} = 1.06(6)(4)$, $ξ= 1.33(8)(8)$ where the first error is statistical and the second systematic. | |
