Neutrinoless double beta decay
The NEXT collaboration is looking for the neutrinoless double beta decay of the Xe-136 isotope. Its discovery might help explain the source of the asymmetry between matter and antimatter in the universe.
The NEXT experiment
The NEXT project is an international collaboration that looks for an hypothetical nuclear process called neutrinoless double-beta decay.

NEXT-100 assembly completed
The assembly of the NEXT-100 detector is complete! Presently, the detector is working at low pressure to test and calibrate the instrumentation. NEXT-100 employs 60 photomultipliers in the energy plane, compared to the 12 PMTs used in its predecessor, NEXT-White. The tracking plane is made up of 3584 SiPMs (1792 in NEXT-White) meant to provide…
