  • Future Plan of the Pandax Experiment
    Future plan of the PandaX Experiment - report at the CJPL International Advisory Committee meeting PandaX Collaboration, 9 Nov., 2016 The PandaX (Particle and astrophysical Xenon) observatory uses xenon as target and detector to search for WIMP particles as well as neutrinoless double beta decay (NLDBD) in 136Xe. At present, the PandaX-II experiment is in operation in CJPL-I. The future PandaX program will pursue the following three main directions: 1. Continue the operation of PandaX-II until a total of 2-year exposure; 2. Develop and operate a multi-ton multi-purpose liquid xenon experiment, PandaX-xT, to push further the dark matter search; 3. Develop and operate a 200-kg (upgradable to ton-scale) high pressure gas TPC (HpgTPC), PandaX-III, to search for NLDBD in 136Xe. Each direction is elaborated below. PandaX-II operation PandaX-II has published the world leading WIMP limit with a 99-day exposure, reaching an upper limit to spin-independent WIMP-nucleon cross section of 2.5x10-46cm2 [1]. The current plan is to maintain stable operation until we have data with a 2-year total live time. Calibration runs will be interleaved to monitor the detector response. The wealth of low background data will allow us to pursue many different physics analyses (in additional to the standard WIMP- nucleon elastic scattering), including constraints to generic WIMP-nucleon operators, light WIMPs, inelastic WIMPs, limits to solar and galactic axions, etc. We will also use the PandaX-II detector to test new technologies for a future multi-ton detector, e.g. online Kr removal, upgrade of the trigger/electronics system to achieve a lower threshold and a higher data bandwidth, alternative electron recoil and nuclear recoil calibrations, etc.

Comparison with luminous mass: → a major accounting problem! Including observations of the expansion history lead to the Standard Model of Cosmology: accounting defcit solved by ~68% Dark Energy, ~27% Dark Matter and <5% “regular” (baryonic) matter. ● Other lines of evidence probe properties of matter under the infuence of gravity: ▸ the equation of state of oscillating matter as observed through fuctuations of the Cosmic Microwave Background (acoustic peaks).

Abstract Although the first hints towards dark matter were discovered almost 100 years ago, little is known today about its properties. Also, dark matter has so far only been inferred through astronomical and cosmological observations. In this work, we therefore investi- gate the influence of astrophysical assumptions on the interpretation of direct searches for dark matter. For this, we assume that dark matter is a weakly interacting massive particle. First, we discuss the development of a new analysis method for direct dark matter searches. Starting from the decomposition of the dark matter velocity distribu- tion into streams, we present a method that is completely independent of astrophysical assumptions. We extend this by using an effective theory for the interaction of dark matter with nucleons. This allows to analyze experiments with minimal assumptions on the particle physics of dark matter. Finally, we improve our method so that arbitrarily strong deviations from a reference velocity distribution can be considered.

  • Session: Neutrino Astronomy
    Session: Neutrino Astronomy Chair: Takaaki Kajita, Institute for Cosmic Ray Research, Univ. of Tokyo Basic natures of neutrinos Neutrino was introduced in 1930 by W. Pauli in order to save the energy conservation law in nuclear beta decay processes, in which the emitted electron exhibits a continuous energy spectrum. It was assumed that the penetration power of neutrinos is much higher than that of the gamma rays. More than 20 years later, the existence of neutrinos was experimentally confirmed by an experiment that measured neutrinos produced by a nuclear power reactor. Since then, the basic nature of neutrinos has been understood through various theoretical and experimental studies: Neutrinos interact with matter extremely weakly. The number of neutrino species is three. They are called electron-neutrino, muon-neutrino and tau-neutrino. In addition, recent neutrino experiments discovered that neutrinos have very small masses. Observing the Universe by neutrinos (1) Because of the extremely high penetration power of neutrinos, neutrinos produced at the center of a star easily penetrate to the outer space. Theories of astrophysics predict that there are various processes that neutrinos play an essential role at the center of stars. For example, the Sun is generating its energy by nuclear fusion processes in the central region. In these processes, low energy electron neutrinos with various energy spectra are generated. Thus the observation of solar neutrinos directly probes the nuclear fusion reactions in the Sun. Another example is the supernova explosion. While the optical measurements observe an exploding star, what is happening in the central region of the star is the collapse of the core of a massive star.

    July 8, 2016 Press Release concerning the 3rd International Neutrino Meeting on Large Neutrino Infrastructures hosted by KEK on the 30-31st of May 2016 “Strengthening global coordination on large neutrino infrastructures” Funding-agency1 and laboratory representatives2 gathered at the 3rd International Meeting on Large Neutrino Infrastructures3 on May 30-31, 2016 at KEK in Tsukuba, Japan to gauge the progress in the global coordination of projects that had been launched during the first and second international meetings4 and to discuss the next steps in the global coordination. The meeting was opened by the 2015 Nobel Prize winner Takaaki Kajita who commented that “Very large-scale experiments will be needed to fully explore neutrino properties. These large-scale experiments will also naturally have astrophysics potential and increase the sensitivity of searches for proton disintegration.” He went on to note that to realise the necessary very large-scale facilities would require “… international coordination and collaboration” and defined the goals of the meeting to be to “… discuss the physics cases and global strategy, including astrophysics and proton decays, which are the part of the aim of this series of meetings; have follow-up discussions of the ICFA Neutrino Panel’s5 roadmap discussion document”6 and to discuss “… the various neutrino experiments, including Hyper- Kamiokande7, toward the realization of an efficient and productive global neutrino program.” In this meeting, the funding-agency and laboratory representatives welcomed the important steps that had been made towards the realisation of the Hyper-Kamiokande (Hyper-K) experiment7. The international proto-collaboration has developed new, high- sensitivity, large-aperture photomultiplier tubes that substantially reduce the total project cost without unduly compromising its potential to address important questions in particle and astroparticle physics and in nucleon decay.

  • Possibilities for Underground Physics in the Pyh\" Asalmi Mine
    CIPANP2018-Trzaska-374 October 3, 2018 Possibilities for Underground Physics in the Pyhasalmi mine W.H. Trzaska1, L. Bezrukov2, T. Enqvist1, J. Joutsenvaara3, P. Kuusiniemi1, K. Loo1, B. Lubsandorzhiev2, V. Sinev2, M. Slupecki1 1Department of Physics, University of Jyvaskyla, Finland 2Institute for Nuclear Research, Russian Academy of Sciences, Moscow, Russia 3Kerttu Saalasti Institute, University of Oulu, Finland The Pyhasalmi mine is uniquely suited to host new generation of large- scale underground experiments. It was chosen both by the LAGUNA- LBNO and by the LENA Collaboration as the preferred site for a giant neutrino observatory. Regrettably, none of these projects got funded. The termination of the underground excavations in the fall of 2019 marks an important milestone. To maintain the infrastructure in good condi- tion a new sponsor must be found: either a large-scale scientific project or a new commercial operation. The considered alternatives for the commer- cial use of the mine include a pumped-storage hydroelectricity plant and a high-security underground data-storage centre. Without a new sponsor the ongoing experiments, including the cosmic-ray experiment EMMA and the study of C14 content in liquid scintillators, have to be completed within the next few years.

Cosmic-ray interactions with nuclei in the atmosphere induce intense show- ers of secondary particles.
