Effects of a new heavy neutral vector boson at SLC and LEP
Models with an extra neutral gauge boson (Z') are discussed. We constrain the Z' mass as a function of its mixing angle with the known Z/sup 0/ by requiring that the Z/sup 0/ mass not be shifted excessively by this mixing, and from the Higgs vacuum expectation value structure of the mass matrix. We compare these limits with those previously found from neutral current experiments. We discuss possible effects of non-excluded models on e/sup +/e/sup -/ physics at SLC and LEP. 8 refs., 3 figs.

Fine structure of the P states in heavy quarkonium and the nature of the spin-dependent potential
Abstract We discuss the failure of existing theories to agree with the experimental measurements of the fine structure of the χ states of the b b and c c systems. We rule out various possible explanations, such as mixing of the 2P triplet with the 1F triplet. We use thefact that the spin-independent potential is well-determined in the relevant range to extract accurate determinations of expectation values of the spin-dependent potentials providing tests for future theories. We find that the usual ansatz that the q q interaction has effective vector and scalar contributions only is very unlikely to be sufficient to explain the fine structure of the 3 P levels and to accomodate the recent measurement of the mass of the 1 P state in charmounium.
