This collaborative award to the University of Washington and Cornell University funds the development of a calorimeter detector that would be used to measure the anomalous magnetic moment of the muon. This quantity is of fundamental interest because of discrepancies between a recent measurement and theoretical predictions of the standard model of particle physics. The magnetic moment of the muon will be measured with greatly increased precision. If the discrepancy is confirmed, it would imply the existence of new subatomic particles, so far undetected, and would fundamentally reshape our understanding of the world around us.

华盛顿大学和康奈尔大学的合作奖资助了一种量热计探测器的开发，该探测器将用于测量μ子的异常磁矩。由于最近的测量结果与粒子物理标准模型的理论预测之间存在差异，这个量具有根本性的意义。测量μ子的磁矩的精度将大大提高。如果这种差异得到证实，它将意味着迄今未被发现的新的亚原子粒子的存在，并将从根本上重塑我们对周围世界的理解。
