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 ¹P₁/³P₁ mixing.

• The first group #NRQCD uses #Lattice QCD - read big computers - to make predictions arxiv.org/abs/hep-lat/... . Here's how their model compares to the data. It fits reasonably well. [9/11] [bsky, 0 points, 1 comments]
