U.S.-Italy Cooperative Research: Topics in Particle Astrophysics

该奖项将支持特拉华大学Bartol研究所的Thomas Gaisser教授和Todor Stanev教授与意大利罗马“La Sapienza”大学的Giulio Auriemma教授的研究合作。研究人员建议调查在世界各地的几个深地下实验室进行的新实验的解释和理论意义，这些实验探测到来自外太空的超高能量自然辐射的残留物。他们将进行计算机模拟和其他必要的计算，以解释同步多μ子、中微子引起的向上μ子以及地表和地下观测之间的相关性的测量结果。他们还将研究测量对宇宙射线物理学、中微子天文学和基本粒子性质的影响。这里提出的工作将与现在正在与意大利拉奎拉的格兰萨索实验室联合进行的新实验相协调。这种支持将有助于显著增加正在进行的粒子天体物理学合作研究。研究人员将利用格兰萨索实验室（Gran Sasso Laboratory）新建的大型地下探测器，如MACRO（单极子、天体物理学和宇宙射线天文台），以及意大利正在规划阶段的其他地下实验。

This award will support Professor Thomas Gaisser and Todor Stanev of the Bartol Research Institute at the University of Delaware in a research collaboration with Professor Giulio Auriemma of the Universita "La Sapienza" in Rome, Italy. The researchers propose to investigate the interpretation and theoretical implications of novel experiments being performed in several deep underground laboratories around the world that detect remnants of ultra-high energy natural radiation from outer space. They will carry out computer simulations and other calculations necessary to interpret measurements of coincident multiple muons, of neutrino-induced upward muons, and of correlations between surface and underground observations. They will also study the implications of the measurements for cosmic ray physics, for neutrino astronomy and for properties of elementary particles. The work proposed here will be coordinated with the new experiments that are coming into operation now in association with the Gran Sasso Laboratory at L'Acquila in Italy. This support will serve to increase significantly ongoing cooperative research in particle-astrophysics. The researchers will take advantage of the operation of major new underground detectors at the Gran Sasso Laboratory such as MACRO (Monopole, Astrophysics and Cosmic Ray Observatory) as well as other underground experiments in the planning stage in Italy.
