Extraction of the b-quark shape function parameters using the Belle B->X_s gamma photon energy spectrum

Abstract

We determine the b-quark shape function parameters, Lambda^SF and lambda_1^SF using the Belle B->X_s gamma photon energy spectrum. We assume three models for the form of the shape function; Exponential, Gaussian and Roman.
