Download B Meson Semileptonic Form Factors Using Unquenched Lattice QCD Book in PDF, ePub and Kindle
Abstract: We present state-of-the-art unquenched lattice QCD results for B meson semileptonic decay, B [rightarrow] [pi]lv, form factors. We use gauge configurations prepared by the MILC collaboration, which include the effects of the sea quarks, the s quark and two very light quarks (u and d). We employ the nonrelativistic NRQCD action to simulate the heavy b quark and a highly improved staggered quark action (AsqTad) to simulate the sea and valence light quarks. To reduce the uncertainties, we perform matching of the heavy-light current with these highly improved actions through one loop. The perturbative matching accounts for the effects of mixing with dimension 4 operators that are O(1/M) and O(a). We extrapolate the form factors f+(q2) and f0(q2) to their values at the physical pion mass using chiral perturbation theory formulas. Integrating this result, we obtain [integral] [from] 16 GeV2 [to] q2_max [d[gamma]/dq2]d2 (V_ub)2 = 1.46(35) ps−1. Combining this with a preliminary average by the Heavy Flavor Averaging Group (HFAG'05) of recent branching fraction data for exclusive B semileptonic decays from the BaBar, Belle and CLEO collaborations, leads to V_ub = 4.22(30)(51) x 10−3.

Download Semileptonic Form Factor Ratio B_s-]D_s/B-]D and Its Application to BR(B0̂_s-]\mu+̂\mu-̂). Book in PDF, ePub and Kindle
We present a (2+1)-flavor lattice QCD calculation of the form factor ratio between the semileptonic decays {bar B}{sub s}° → D{sub s}l−{bar {nu}} and {bar B}° → D+l−{bar {nu}}. This ratio is an important theoretical input to the hadronic determination of the B meson fragmentation fraction ratio f{sub s}/f{sub d} which enters in the measurement of BR(B{sub s}° →?+?−). Small lattice spacings and high statistics enable us to simulate the decays with a dynamic final D meson of small momentum and reliably extract the hadronic matrix elements at nonzero recoil. We report our preliminary result for the form factor ratio at the corresponding momentum transfer of the two decays f0{sup (s)} (M{sub {pi}}2)/f0{sup (d)} (M{sub K}2).
