Probing CP violation with the three years ultra-high energy neutrinos from IceCube

Understand

The IceCube collaboration has recently announced the discovery of ultra-high energy neutrino events.

• These neutrinos can be used to probe their production source, as well as leptonic mixing parameters.
• In this work, we have used the first IceCube data to constrain the leptonic CP violating phase $\delta_{cp}$.
• For this, we have analyzed the data in the form of flux ratios.
