U. Cotti et al., EXACT FORMULAS FOR HIGGS PRODUCTION THROUGH E-GAMMA-]EH IN THE NONLINEAR R-XI-GAUGE, Physics letters. Section B, 404(3-4), 1997, pp. 308-314
We study the production of the SM Higgs boson (H-0) at future e gamma
colliders, through the reaction e gamma -->eH(0). The amplitude is eva
luated using the non-linear R-xi-gauge, which greatly simplifies the c
alculation. Complete analytical expressions for the amplitudes are pre
sented, which include the contributions from 1-loop triangles gamma ga
mmaH-0 and gamma Z*H-0 as well as the W- and Z-boxes with their relat
ed eeH(0) triangle graphs. The resulting cross section for this mechan
ism indicates that it could be used to detect the Higgs signal and to
test its properties. (C) 1997 Published by Elsevier Science B.V.
