Cosmic ray air showers from sphalerons.

Brooijmans, Gustaaf and Schichtel, Peter and Spannowsky, Michael (2016) 'Cosmic ray air showers from sphalerons.', Physics letters B., 761 . pp. 213-218.


The discovery of the Higgs boson marks a key ingredient to establish the electroweak structure of the Standard Model. Its non-abelian gauge structure gives rise to, yet unobserved, non-perturbative baryon and lepton number violating processes. We propose to use cosmic ray air showers, as measured, for example, at the Pierre Auger Observatory, to set a limit on the hadronic production cross section of sphalerons. We identify several observables to discriminate between sphaleron and QCD induced air showers.
