OSTI ID:10500
The authors report on two spectroscopy results from CDF. First, they observe the orbitally excited B** mesons in B {r_arrow} {ell}D(*) X events. They find 28 {+-} 6 {+-} 3% of light B mesons produced are B** states. A collective mass fit results in a B{sub 1} mass of 5.71 {+-} 0.02 GeV/c{sup 2}. Secondly, they observe 20.4{sub {minus}5.5}{sup +0.18} {+-} 0.03 ps lifetime. The production rate is in reasonable accordance with expectations.
