Neutrino masses are yet unknown. We discuss the present state of effective electron antineutrino mass from β decay experiments; effective Majorana neutrino mass from neutrinoless double-beta decay experiments; neutrino mass squared differences from neutrino oscillation: solar, atmospheric, reactor, and accelerator-based experiments; sum of neutrino masses from cosmological observations. Current experimental challenges in the determination of neutrino masses are briefly discussed. The main focus is devoted to contemporary experiments.

“…As for the muon collider design, we take positron on target method (LEMMA) as an example, which has been proposed for high quality muon beam production [9,10] (Earlier studies using proton on target muon beams can be found in Refs. [11][12][13] ) Although it is still quite challenging to achieve enough high luminosity for muon beam collisions [6,7], we find it quite promising for neutrino oscillation studies, with comparable or even larger neutrino flux than other long baseline neutrino experiments, with more details to be discussed below. In the LEMMA approach, the incident positron energy is around 45 GeV, producing collimated muon pairs with opening angles of around 0.005 rad.…”

We propose here a proposal to connect neutrino and energy frontiers, by exploiting collimated muon beams for neutrino oscillations, which generate symmetric neutrino and antineutrino sources: µ + → e + νµ νe and µ − → e − νµ νe. Interfacing with long baseline neutrino detectors such as DUNE and T2K, this experiment can be applicable to measure tau neutrino properties, and also to probe neutrino CP phase, by measuring muon electron (anti-)neutrino mixing or tau (anti-)neutrino appearance, and differences between neutrino and antineutrino rates. There are several significant benefits leading to large neutrino flux and high sensitivity on CP phase, including 1) collimated and manipulable muon beams, which lead to a larger acceptance of neutrino sources in the far detector side; 2) symmetric µ + and µ − beams, and thus symmetric neutrino and antineutrino sources, which make this proposal ideally useful for measuring neutrino CP violation. More importantly, νe,µ → ντ and νe,µ → ντ , and, νe → νµ and νe → νµ oscillation signals can be collected simultaneously, with no needs for separate specific runs for neutrinos or antineutrinos. Furthermore, it is possible to exchange µ + and µ − flying routes, thus further reducing possible bias or systematic uncertainties. In an optimistic way, we estimate 10 4 tau (anti-) neutrinos can be collected per year thus this proposal can serve as a brighter tau neutrino factory. Moreover, 5 standard deviations of sensitivity can be easily reached for CP phase as |π/2|, with only 1-2 years of data taking, by combining tau and muon (anti-) neutrino appearances. With the development of a more intensive muon beam targeting future muon collider, the neutrino potential of the current proposal will surely be further improved.

“…Currently, the radon measurement methods worldwide mainly include the ionization chamber, electrostatic adsorption, and liquid scintillator measurement methods. Among them, due to the advantages of a high solubility coefficient and a low background, the liquid scintillator measurement method is widely used in dark matter and neutrino experiments, such as Jiangmen Underground Neutrino Observatory (JUNO) [5,6] and China Jinping Underground Laboratory (CJPL) [7,8]. Moreover, they all require high sensitivity for low-background detectors for radon measurements.…”

Study on SiPM performance at low temperatures between -60°C and -20°C

Radon is the main background source of dark matter and neutrino experiments. Radon concentration (mBq/m3) measurement by liquid scintillation detector is a highly sensitive method at low temperatures using silicon photomultipliers (SiPMs) arrays. The SiPM performance characteristics are closely related to the lower detection limit of the detector. In this study, we built an automatic and accurate low-temperature measurement system to study the single photoelectron (SPE) spectrum, SPE resolution, optical crosstalk, and after-pulse of the SiPM at different temperatures. As a result, we obtained the variation trend of the SiPM parameters at different temperatures, and the SiPM optimal working conditions were obtained, which can improve the detector's sensitivity.
