16 Feb 1996 | Journal: | Phys.Lett. B382 (1996) 131-137 | Abstract: | We present first results for $B_c$ spectroscopy using Lattice Non-Relativistic QCD (NRQCD). For the NRQCD action the leading order spin-dependent and next to leading order spin-independent interactions have been included with tadpole-improved coefficients. We use multi-exponential fits to multiple correlation functions to extract ground and excited $S$ states and give accurate values for the $S$ state hyperfine splitting and the P state ($B^{**}_c$) fine structure, including the effects of $^1P_1/^3P_1$ mixing. | Source: | arXiv, hep-lat/9602020 | Services: | Forum | Review | PDF | Favorites |
