Pulsar wind nebulae (PWNe) are main gamma ray emitters in the Galactic plane. The detection of high-energy gamma rays from some PWNe makes them interesting sources to IceCube. Although the leptonic scenario is able to explain most PWNe emission well, a hadronic contribution cannot be excluded. In addition to electrons, relativistic hadrons may be present in PWNe. If PWNe are Pevatrons, TeV-PeV neutrinos produced through hadronic processes would contribute to IceCube events. We perform a stacking analysis to search for neutrinos from PWNe that are high-energy gamma ray emitters using all-sky IceCube data.
