Abstract: The Borexino detector, located at the Laboratori Nazionali del Gran Sasso in Italy, is a liquid scintillator detector with a primary goal to measure solar neutrinos. The *pp* fusion chain has been measured in Borexino with an outstanding precision through the detection of *pp*, *pep*, $^{7}$Be, and $^{8}$B neutrinos. It is well motivated by standard solar models that around 1 per cent of the solar energy is fueled by the so-called Carbon-Nitrogen-Oxygen (CNO) cycle. A direct measurement of the CNO cycle is difficult due to the high spectral correlation with the background isotope $^{210}$Bi and *pep* neutrinos. The sensitivity to CNO neutrinos was evaluated through a likelihood-ratio test, based on thousands of pseudo-experiments analyzed with a counting analysis as well as spectral fit. This poster presents the resulting discovery potential of Borexino towards the CNO cycle in the Sun.
