This $295,792 Project Grant award, funded by the National Science Foundation (NSF) under the Mathematical and Physical Sciences (CFDA 47.049) program, supports research to precisely measure the strength of a weak optical interaction in atomic cesium. The goal is to improve the precision of the electro-weak mixing angle, which could help validate the Standard Model of particle physics or potentially discriminate between various "Beyond Standard Model" physics theories. The key...

This federal Project Grant award from the National Science Foundation (NSF) under the Mathematical and Physical Sciences program (CFDA 47.049) provides $129,851 to Florida State University to conduct research aimed at measuring the mass of the electron with an unprecedented level of precision. The key objectives are: Measure the mass of the electron to 10 parts-per-trillion uncertainty, which is three times more precise than previous best measurements. This improved electron mass value is...
