Debasish Borah, Arnab Dasgupta, Ujjal Kumar Dey, Gaurav Tomar Physical Review D 101, 075039 (2020) https://doi.org/10.1103/PhysRevD.101.075039 Abstract The ANtarctic Impulsive Transient Antenna (ANITA) Collaboration has observed two EeV-energy, upward-going events originating from below the horizon. As no standard-model (SM) particles propagating through the Earth at such energy and exit angles can give rise to the required survival probability for the observed events, severa
