Phys. Rev. Lett. 69, 2037–2040 (1992)Probing ultraheavy quanta with photon-photon or gluon-gluon scatteringReceived 24 March 1992; published in the issue dated 5 October 1992 The existence of ultraheavy quanta too heavy to produce directly may be probed by means of the rising cross sections they would induce in scattering at the TeV energy scale of photon or gluon pairs to weak boson pairs, for instance γγ→ZZ or gg→ZZ. © 1992 The American Physical Society URL:
