%0 Journal Article %T Determination of the b-quark mass and nonperturbative parameters in semileptonic and radiative penguin decays at BABAR %A Kerstin Tackmann %A for the BABAR collaboration %J Physics %D 2008 %I arXiv %R 10.1140/epja/i2008-10645-y %X Knowing the mass of the b-quark is essential to the study of the structure and decays of B mesons as well as to future tests of the Higgs mechanism of mass generation. We present recent preliminary measurements of the b-quark mass and related nonperturbative parameters from moments of kinematic distributions in charmed and charmless semileptonic and radiative penguin B decays. Their determination from charmless semileptonic B decays is the first measurement in this mode. The data were collected by the BABAR detector at the PEP-II asymmetric-energy e+e- -collider at the Stanford Linear Accelerator Center at a center-of-momentum energy of 10.58 GeV. %U http://arxiv.org/abs/0801.2985v2
