The absolute scale of the neutrino mass plays a critical role in physics at every scale, from subatomic to cosmological. Measurements tritium end-point spectrum have provided most precise direct limit on scale. In this Letter, we present advances by Project 8 cyclotron radiation emission spectroscopy (CRES) technique culminating first frequency-based limit. With only cm^{3}-scale physical detection volume, m_{β}<155 eV/c^{2} (152 eV/c^{2}) is extracted background-free measurement continuous...
Neutrino mass is a key parameter in nuclear and particle physics cosmology. The Project 8 Collaboration developed an innovative method with potential to improve the current limits by more than order of magnitude. Announced paper published last September (PRL 131, 102502; see also Synopsis at https://physics.aps.org/articles/v16/s121), measures frequency radiation from tritium $\ensuremath{\beta}$-decay electrons spiraling magnetic field. In authors provide details this unique measurement...
Bayesian modeling techniques enable sensitivity analyses that incorporate detailed expectations regarding future experiments. A model-based approach also allows one to evaluate inferences and predicted outcomes, by calibrating (or measuring) the consequences incurred when certain results are reported. We present procedures for predictions of an experiment's both continuous discrete parameters. Using these a new model $\ensuremath{\beta}$-decay spectrum, we assess high-precision neutrino mass...
Abstract Cyclotron Radiation Emission Spectroscopy (CRES) is a technique for measuring the kinetic energy of charged particles through precision measurement frequency cyclotron radiation generated by particle's motion in magnetic field. The Project 8 collaboration developing next-generation neutrino mass experiment based on CRES. One approach to use phased antenna array, which surrounds volume tritium gas, detect and measure resulting β-decay electrons. To validate feasibility this method,...
The half-life of the $^{20}$F ground state has been measured using a radioactive beam implanted in plastic scintillator and recording $\beta\gamma$ coincidences together with four CsI(Na) detectors. result, $T_{1/2} = 11.0011(69)_{\rm stat}(30)_{\rm sys}$~s, is at variance by 17 combined standard deviations two most precise results. present value revives poor consistency results for this calls new measurement, technique having different sources systematic effects, to clarify discrepancy.
Abstract The objective of the cyclotron radiation emission spectroscopy (CRES) technology is to build precise particle energy spectra. This achieved by identifying start frequencies charged trajectories which, when exposed an external magnetic field, leave semi-linear profiles (called tracks) in time–frequency plane. Due need for excellent instrumental resolution application, highly efficient and accurate track reconstruction methods are desired. Deep learning convolutional neural networks...

Abstract Cyclotron radiation emission spectroscopy (CRES) is a modern approach for determining charged particle energies via high-precision frequency measurements of the emitted cyclotron radiation. For CRES experiments with gas within fiducial volume, signal and noise dynamics can be modelled by hidden Markov model. We introduce novel application Viterbi algorithm in order to derive informational limits on optimal detection signals this class gas-filled experiments, thereby providing...
