Analyzing the full CDF Run II data set of 9.6 fb−1, we find first evidence for a new resonance in B0π+ and B+π− mass distributions with a significance of 4.4 standard deviations. We determine its mass, width, and relative production rate and refer to it as the B(5970) state. Also, we present the first study of orbitally excited B+ mesons and updated results on orbitally excited B0 and B0s mesons. We examine the B1 and B∗2 states and measure masses, widths, their relative production rate, the branching fraction of the B∗0s2 state, and the production rate of the orbitally excited B0 states relative to the B0 ground state.
