Abstract

Quarkonium states with unequal quark masses, such as K, D, D-s, B, and B-s systems, are analyzed by fitting the observed mass spectra. Since these systems are important in checking CP violations and the main uncertainties originate from estimating strong coupling constant alpha(s), it is essential to deduce the values of for these systems. We haveused least-squares method to determine parameters, and the determinedvalues of alpha(s) are consistent with other experimental results andgo up for light quarkonium systems.
