N2 - We discuss the possible production and discovery channels in e+e- and pp machines of the Xb, the bottomonium counterpart of X(3872) and the putative isoscalar analogue of the charged bottomoniumlike states Zb discovered by Belle. We suggest that the Xb may be close in mass to the bottomonium state χb1(3P), mixing with it and sharing its decay channels, just as X(3872) is likely a mixture of a D¯D∗ molecule and χc1(2P). Consequently, the experiments which reported observing χb1(3P) might have actually discovered the Xb, or a mixture of the two states.
