About Paper:

The weak force interaction is a major topic of study in the field of nuclear particle physics. It is notable for the phenomenon of Parity Non Conservation, also known as PNC, where the principle of parity symmetry is broken. Furthermore, various interactions do not obey the basic standard model of particle physics, and therefore various extensions to the standard model have been proposed. In order to constrain these extensions, this research aims to conduct measurements of different electric dipole matrix elements in the cesium nucleus. By measuring these elements precisely, we can measure precisely the value of the beta constant. By combining a precise measurement of beta with a theoretically computed value for M1HF, it is possible to compute EPNC, which allows measurement of the weak charge. Ultimately the goal of this research is to arrive at an extremely precise measurement of the strength of the weak force, which can explicitly rule out certain extensions to the standard model of particle physics. These precision measurements were obtained through various optical setups. Important tasks ranged from constructing stable high-speed voltage switching sources, stabilizing laser power and frequency, and CMOS beam profilers. Measurement systems included Lock-in amplifiers, photodiodes, and spectrum analyzers. Keywords: Cesium; PNC; Optics; Quantum
