Abstract
A search for the production of events containing three W bosons is reported. The search is based on a data sample of proton-proton collisions at s√=13TeV recorded by the CMS experiment and corresponding to a total integrated luminosity of 35.9fb−1. The search is performed in final states with two leptons (electrons or muons) of the same charge or with three leptons. The observed (expected) significance for WWW production is 0.60 (1.78) standard deviations, and the ratio of measured signal yields to that expected from the standard model is 0.34+0.62−0.34. Limits are also placed on anomalous quartic gauge couplings and on the production of massive axion-like particles.
