Abstract

A new limit has been set on neutrinoless double beta decay, a process which would require lepton number nonconservation, plus one other piece of new physics. That second item might be light Majorana electron neutrino mass, a very heavy Majorana neutrino, right-handed currents, or supersymmetric particles in theories with R-parity violation. Limits on all these quantities can be obtained from the result that the UCSB/LBL Ge multidetector system shows the halflife for $^{76} Ge →^{76} Se + 2 e^{−} to be > 1.2 × 10^{24} y$ at the 90% confidence level or >2.4 × 10²⁴y at the 68% confidence level.

Low Background Counting at LBNL
2015, Physics Procedia
The Low Background Facility (LBF) at Lawrence Berkeley National Laboratory in Berkeley, California provides low background gamma spectroscopy services to a wide array of experiments and projects. The analysis of samples takes place within two unique facilities; locally within a carefully-constructed, low background cave and remotely at an underground location that historically has operated underground in Oroville, CA, but has recently been relocated to the Sanford Underground Research Facility (SURF) in Lead, SD. These facilities provide a variety of gamma spectroscopy services to low background experiments primarily in the form of passive material screening for primordial radioisotopes (U, Th, K) or common cosmogenic/anthropogenic products, as well as active screening via Neutron Activation Analysis for specific applications. The LBF also provides hosting services for general R&D testing in low background environments on the surface or underground for background testing of detector systems or similar prototyping. A general overview of the facilities, services, and sensitivities is presented. Recent activities and upgrades will also be presented, such as the completion of a 3π anticoincidence shield at the surface station and environmental monitoring of Fukushima fallout. The LBF is open to any users for counting services or collaboration on a wide variety of experiments and projects.
Installation of a muon veto for low background gamma spectroscopy at the LBNL low-background facility
2013, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
An active veto system consisting of plastic scintillation panels was installed outside the Pb shielding of a 115% n-type HPGe detector in an effort to reduce background continuum generated by cosmic ray muons on the surface. The Low Background Facility at the Lawrence Berkeley National Laboratory performs low level assay (generally of primordial U, Th, K) of candidate construction materials for experiments that require a high level of radiopurity. The counting is performed in two facilities: one local surface site and a remote underground site of approximately 600 m.w.e. For the recently installed veto system at the surface location, the top scintillator panel has been in use for nearly 1 year and the full $3 π$ anticoincidence shield was commissioned into normal counting operations in January 2013. The integrated background from 20 to 3600 keV is reduced overall by a factor of 8, where most of the energy spectrum above 100 keV achieves an overall reduction that varies from 8 to 10. A dramatic improvement of peak-to-background across the entire continuum is observed, greatly enhancing low-level peaks that would otherwise be obscured.
On the measurement of the neutrino magnetic moment
2002, Progress in Particle and Nuclear Physics
The present status of searches for the neutrino magnetic moment (NMM) down to 3×10⁻¹¹ μ_B is briefly discussed. The low background Ge-NaI spectrometer GEMMA constructed in ITEP for NMM measurement is described and the results of the test background measurements at a small depth of 5 m.w.e in ITEP are reported. The analysis of these results shows that the limit on NMM at the level (2 ÷ 3)·10⁻¹¹ μ_B can be achieved during 2 year duration of measurements with spectrometer GEMMA at Kalininskaya Nuclear Power Plant (KNPP). The prospects of breakthrough to the limit on NMM about 10⁻¹² μ_B are outlined.
Particle physics implications of neutrinoless double beta decay
1999, Nuclear Physics B - Proceedings Supplements
Neutrinoless double beta decay is a sensitive probe of the patterns of neutrino masses and mixings if the neutrinos are Majorana particles as well as other new physics scenarios beyond the standard model. In this talk, the present experimental lower bound on the lifetime for ββ_0ν is used to constrain the neutrino mixings and set limits on the parameters of the new physics scenarios such as the left-right symmetric models, R-parity violating SUSY models etc which lead to neutrinoless double beta decay. We then discuss proposed high precision searches for ββ_0ν decay that can provide extremely valuable insight not only into the nature of neutrino mixings and masses but also put constraints on (or even rule out) new physics scenarios.

Heavy sterile neutrinos and neutrinoless double beta decay
1995, Nuclear Physics, Section B
We investigate the possibility of producing neutrinoless double beta decay without having an electron neutrino with a mass in the vicinity of 1 eV. We do so by having a much lighter electron neutrino mix with a much heavier ( $m ⪆ 1 GeV$ ) sterile neutrino. We study the constraints on the masses and mixings of such heavy sterile neutrinos from existing laboratory, astrophysical and cosmological information, and discuss the properties it would require in order to produce a detectable signal in current searches for neutrinoless double beta decay.
