Research in Elementary Particle Physics

这笔赠款支持范德比尔特大学的一个由四名物理学家组成的小组从事几个费米实验室实验以及中微子天文实验DUMAND(深水下缪子和中微子探测器)的设计和原型工作。费米实验室的实验是：E743，研究迷人的强子产生；和E683，研究高能光子产生的喷流。费米实验室的一项实验使用高能粒子来创造和研究一些更重、更不寻常的夸克--这种夸克具有一种被称为“魅力”的特征。另一项实验将高能光子引向质子；仔细研究在某些相互作用中产生的粒子“喷流”将揭示“胶子”粒子的一些特征，“胶子”粒子是将质子、中子和原子核结合在一起的力场的量子。DUMAND的工作是为观测来自天体物理源的超高能中微子而提议的探测器。

This grant supports a group of four physicists from Vanderbilt University for work on several Fermilab experiments and for design and prototype work on the neutrino astronomy experiment DUMAND (Deep Underwater Muon and Neutrino Detector). The Fermilab experiments are: E743, a study of charmed hadron production; and E683, a study of jets produced by high energy photons. One of the Fermilab experiments uses high energy particles to create and study some of the heavier and more unusual quarks--the quarks which carry the characteristic called "charm". Another experiment directs high energy photons at protons; careful study of the "jets" of particles produced in some of the interactions will reveal some of the characteristics of the "gluon" particle, the quantum of the force field which holds protons, neutrons and nuclei together. The work on DUMAND is for a proposed detector for observation of ultra-high energy neutrinos from astrophysical sources.
