Study of Higgs Self-coupling at ILC

Abstract

In this Analysis we investigated the possibility of the measurement of Higgs self-coupling at ILC through the process $e^{+}+e^{-}\to ZHH$ using fast simulation data. So far two combinations of decay modes: $Z\to q\bar{q},H\to b\bar{b},H\to W{W}^{\ast }$ and $Z\to l\bar{l},H\to b\bar{b},H\to b\bar{b}$ were studied. Our preliminary results show that it is very challenging to suppress the huge standard model backgrounds effectively.
