Abstract
In this dissertation, we investigate the properties (spectrum, radiative widths and strong decay widths) of open-bottom (B,Bs and Bc) mesons. We use the non-relativistic quark potential model to calculate the masses and wave functions of the mesons. We numerically solve the radial Schr¨odinger equation by using the shooting method to find energy eigenvalues. The radiative transitions are evaluated using the Coulomb plus linear plus smeared hyperfine wave functions. We predict strong decay amplitudes by assuming simple harmonic oscillator(SHO)wavefunctionsin themodified 3P0 model. Thesimpleharmonic oscillator parameter β for different states of mesons are obtained by fitting the SHO wave function to the corresponding quark model wave function. The total decay widths of different states of open-bottommesonsarepredictedbyincludingtheradiativeandstrongwidths. Thesetotal widths are further used to calculate the branching ratios of each decay channel for a specificinitialstateofopen-bottommesons. Thetheoreticallypredictedmassesandtotaldecay widthsarecomparedtoexperimentwherepossibleandusedtomakeassignmentsfortherecentlydiscoveredstatesofopen-bottommesons. Thepredictedpropertiesofdifferentstates of open-bottom mesons can be helpful for future experimental searches and also to test our theoretical understanding against experimental measurements once they are available.
