EXO-200 Sets New Limit on 0νββ in 136Xe

Neutinoless Double Beta Decay Limits

Relation between the T1/20νββ in 76Ge and 136Xe for different matrix element calculations (GCM [22], NSM [23], IBM-2 [24], RQRPA-1 [25] and QRPA-2 [5]). For each matrix element ‹m›ββ is also shown (eV). The claim [4] is represented by the grey band, along with the best limit for
76Ge [21]. The result reported here is shown along with that from [7].
