Sample interview questions: What is your opinion on the potential for discovering new phenomena through precision measurements of the electromagnetic force in particle physics?
Sample answer:
Precision measurements of the electromagnetic force in particle physics hold immense potential for the discovery of new phenomena. Here’s why:
1. High Sensitivity to Beyond-Standard-Model Physics:
The electromagnetic force is described by the Standard Model of Physics, which is widely accepted to be incomplete. Precision measurements can probe subtle deviations from Standard Model predictions, indicating the presence of new particles or interactions.
2. Probe for Axion and Dark Matter:
Axions and dark matter are hypothetical particles that could interact with the electromagnetic force. Measuring the electromagnetic properties of these particles can provide insights into their nature and existence.
3. Study of CP Violation and Baryon Asymmetry:
The electromagnetic force plays a crucial role in understanding the violation of charge-parity (CP) symmetry and the generation of baryon (matter) over anti-baryon (anti-matter). Precision measurements can shed light on these fundamental questions.
4. Testing Quantum Field Theory:
The electromagnetic force is a fundamental force in quantum field theory (QFT). Precision measureme… Read full answer
