Fig. 3: Projected point source sensitivities and discovery potentials of TRIDENT.

From: A multi-cubic-kilometre neutrino telescope in the western Pacific Ocean

Fig. 3

All-sky point source 90% confidence-level median sensitivity (dashed dot lines) and 5σ discovery potential (solid lines) of TRIDENT with 10 years of data taking. The left panel corresponds to a source energy spectrum index of 2 (labelled E−2) and minimum energy of 10 TeV, while the right panel assumes an index of 3 (E−3) and minimum energy of 1 TeV. The x axis represents the sine declination (sinδ) and the y axis is the neutrino flux (ϕ). KM3NeT, IceCube and IceCube-Gen2 sensitivities15,66,67 are also shown for comparison. IceCube, located at the South Pole, has increased sensitivity to the northern sky. For a source located in the southern sky with a spectral index of 3, TRIDENT will have 4 orders of magnitude improvement in sensitivity compared with IceCube. Similarly comparing to the future telescope KM3NeT located in the Northern Hemisphere yields an improvement factor of approximately 5.
