# Quartic Higgs coupling at hadron colliders

@article{Plehn2005QuarticHC, title={Quartic Higgs coupling at hadron colliders}, author={Tilman Plehn and Michael Rauch}, journal={Physical Review D}, year={2005}, volume={72}, pages={053008} }

The quartic Higgs self-coupling is the final measurement in the Higgs potential needed to fully understand electroweak symmetry breaking. None of the present or future colliders are known to be able to determine this parameter. We study the chances of measuring the quartic self-coupling at hadron colliders in general and at the very large hadron collider in particular. We find the prospects challenging.
