Available in PDF, EPUB and Kindle. Book excerpt: The B{sub c}{sup ±} meson is observed through the decay B{sub c}{sup ±} → J/[psi] [pi]{sup ±}, in data corresponding to an integrated luminosity of 2.4 fb−1 recorded by the CDF II detector at the Fermilab Tevatron. A signal of 108 {+-} 15 candidates is observed, with a significance that exceeds 8[sigma]. The mass of the B{sub c}{sup {+-}} meson is measured to be 6275.6 {+-} 2.9(stat.) {+-} 2.5(syst.) MeV/c2.
