Correspondence between nonstandard interactions and CPT violation in neutrino oscillations

Abstract

The experimental signatures of nonstandard neutrino interactions are shown to be equivalent to CPT violation in neutrino oscillations. This result leads to a correspondence in the study of these two descriptions that can be used to constrain the relevant parameters of one formalism by using the available bounds on parameters of the other. The correspondence is illustrated and explicitly used to determine first bounds on previously unexplored parameters in both formalisms.
