Solar Neutrinos: Experimental Program

太阳中微子:实验计划

基本信息

项目摘要

Measurements of the solar neutrino spectrum have already yielded unexpected results of fundamental importance and, as these measurements improve, new results promise to be equally revealing. Neutrino oscillations, coupled with the MSW mechanism, are required to explain the observed neutrino fluxes at Earth. This solution allows an interesting region between vacuum- and matter-enhanced oscillations where additional new physics can be probed. Likewise, recent solar abundance measurements have created conflicts between the Standard Solar Model and helioseismology results, which are most sensitively resolved by measurement of the CNO neutrino flux. Significantly, there also remains the question whether the luminosity of the sun, as determined by photons, accurately matches the luminosity as determined by neutrinos. In this case, a direct measurement of the pp neutrinos is also required. This award will provide funding for this group to continue their participation in the science arena of Borexino in the underground laboratory at Gran Sasso, Italy as the collaboration focuses on measuring the Beryllium-7 neutrino flux. The group actively participated and provided expert manpower to Borexino purification efforts. Results from the first pass of purification have been very successful, and when completed in the coming year, Borexino looks well poised to provide meaningful measurements of the CNO and pep fluxes as well. Future possibilities include measurements of the pp neutrino flux with the LENS experiment. This award will provide excellent training of, and experience for, the students and postdocs who work in the program as well as potential applications of these technologies outside of the field.
对太阳中微子光谱的测量已经产生了意想不到的具有根本重要性的结果,随着这些测量的改进,新的结果有望同样具有启发性。中微子振荡,再加上MSW机制,需要解释在地球上观察到的中微子通量。这种解决方案允许真空和物质增强振荡之间的一个有趣的区域,在那里可以探索额外的新物理。同样,最近的太阳丰度测量也在标准太阳模型和日震学结果之间产生了冲突,这是通过测量CNO中微子通量最敏感地解决的。值得注意的是,由光子决定的太阳光度是否与由中微子决定的太阳光度准确匹配,仍然是一个问题。在这种情况下,还需要直接测量pp中微子。该奖项将为该小组提供资金,以继续参与意大利Gran Sasso地下实验室的Borexino科学竞技场,因为合作的重点是测量Berxino-7中微子通量。该集团积极参与并为Borexino净化工作提供专家人力。第一次净化的结果非常成功,当明年完成时,Borexino看起来也准备好提供对CNO和PEP通量的有意义的测量。未来的可能性包括用透镜实验测量pp中微子通量。该奖项将为在该项目中工作的学生和博士后提供出色的培训和经验,以及这些技术在该领域之外的潜在应用。
