| We study the B meson spectroscopy allowing the mixture of conventional P wave quark-antiquark states and four-quark components. A similar picture was used to describe the new D(J) and D(sJ) open-charm mesons. The four-quark components shift the masses of some positive parity B(sJ) states below their corresponding isospin preserving two-meson threshold and therefore they are expected to be narrow. Electromagnetic decay widths are analyzed. | |||
