Bbar {right arrow} {pi}l {nu bar}}at three lattice spacings

PDF Version Also Available for Download.

Description

The increasing accuracy of experimental results for the exclusive, semileptonic decay {anti B}{yields}{pi}l{anti {nu}} requires a similarly acucrate calculation of the hadronic matrix elements, to determine {vert_bar}V{sub ub}{vert_bar}. We present preliminary results for the form factors of the B to light meson decay mode. Using results from three lattices in the range 5.7{<=}{beta}{<=}6.1 we study the dependence on the lattice spacing.
