标题： A Model-independent Way to Measure $|V_{ub}/V_{cb}|$

摘要： TO_BE_TRANSLATED: We propose a new model-independent method, to determine the ratio $|V_{ub}/V_{cb}|$, which is theoretically described by the phase space factor and the well-known perturbative QCD correction only. We explore the possible experimental options: the measurement of inclusive hadronic invariant mass distributions. We also discuss the relevant experimental backgrounds. 显示英文摘要
