Search for nucleon decays with EXO-200
Abstract
A search for instability of nucleons bound in ¹³⁶Xe nuclei is reported with 223 kg·yr exposure of ¹³⁶Xe in the EXO-200 experiment. Lifetime limits of 3.3×10²³ and 1.9×10²³ yr are established for nucleon decay to Sb133 and Te133, respectively. These are the most stringent to date, exceeding the prior decay limits by a factor of 9 and 7, respectively.
