Experimental perspectives on HHH production

There has recently been increased theoretical interest in tri-Higgs production, but no experimental search or measurement has yet been performed. Several significant challenges would be faced, including signal identification and discrimination against background, modelling of complex background processes, and interpretation of the data. This talk will present an experimentalist's view of these challenges, together with lessons learned from past studies targeting di-Higgs production, particularly at ATLAS, and an overview of techniques which may potentially be useful to address them.
