Possibility of Studying Electroweak Symmetry Breaking at γγColliders

Abstract

The studies of the electroweak symmetry breaking sector (EWSBS) at $γγ$ colliders were considered previously in the loop processes of $γγ\to w_Lw_L,\,z_Lz_L$, but they are suffered from the huge $W_T W_T$ and $Z_TZ_T$ backgrounds. Here we present another possible process that involves spectator $W$'s and $W_L$'s, the latter of which are scattered strongly by the interactions of the EWSBS. We also show that this process should be safe from the transverse backgrounds and it can probe the structure of the EWSBS.
