TESTING ANOMALOUS HIGGS COUPLINGS IN TRIPLE PHOTON PRODUCTION AT THE TEVATRON COLLIDER

We derive bounds on Higgs and gauge-boson anomalous interactions using the CDF data for the process <p(p)over bar> --> gamma gamma gamma + X . We use a linearly realized SUL(2) X U-Y(1) invariant effective Lagra ngian to describe the bosonic sector of the Standard Model, keeping th e fermionic couplings unchanged. All dimension-six operators that lead to anomalous Higgs interactions involving gamma and Z are considered. We also show the sensitivity that can be achieved for these couplings at Fermilab Tevatron upgrades. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
