Description

We list the set of C and P conserving anomalous quartic vector boson self-couplings which can be tested at LEP2 through triple vector boson production. We show how this set can be embedded in manifestly SU(2) x U(1) gauge invariant operators exhibiting an SU(2)c global symmetry. We derive bounds on these various couplings and show the most relevant distributions that can enhance their contribution. We also find that an e+e- collider running at 500 GeV can improve the LEP2 limits by as much as three-orders of magnitude. (orig.)
