Getting the best out of T2K and NOvA

Understand

We explore the combined physics potential of T2K and NOvA in light of the moderately large measured value of theta13.

• For sin^2 2*theta13 = 0.1, which is close to the best fit value, a 90% C.L.
• evidence for the hierarchy can be obtained only for the combinations (Normal hierarchy, -170 <= deltaCP <= 0) and (Inverted hierarchy, 0 <= deltaCP <= 170), with the currently planned runs of NOvA and T2K.
• However, the hierarchy can essentially be determined for any value of deltaCP, if the statistics of NOvA are increased by 50% and those of T2K are doubled.
