Direct measurement of the Higgs self-coupling in e+e− → ZH
A new method to measure the trilinear Higgs self-coupling λ3 in a single Higgs production process is proposed. Time-reversal-odd (T-odd) asymmetries in the process e+e−→ZH, Z→ff¯ are computed from the absorptive part of the electroweak one-loop amplitude. Since the T-odd asymmetries measure the tree...
