Mass spectrum of orbitally excited B_s mesons in a non relativistic quark model with hulthen potential

Heavy light mesons composed of one heavy quark and one light quark. They are the only mesons containing quarks of the third generation. Understanding the B mesons will give a more complete understanding of excited mesons and will also help put the newly discovered excited charmed mesons into the larger context. In this respect, the physics of B mesons is complementary to that of the K mesons, which has contributed enormously to our understanding of elementary particles and their interactions. The rare decay of a neutral B meson to two oppositely charged kaons has been observed for the rst time in LHCb experiment at CERN. B mesons are created when protons collide in the Large Hadron Collider and the observed decay happens to fewer than one in ten million B mesons. Despite many of the B_s states should be accessible by the B-factories (CLEO, BaBar, Belle) and also by the proton antiproton colliders (CDF and D0), much of the bss-bar excitation spectrum remains to be observed
