’t Hooft-Veltman model
Quick Summary
The \u2019t Hooft-Veltman model is a mathematical framework developed by Gerardus \u2019t Hooft and Martinus J.G. Veltman. It was crucial for making the electroweak theory a workable model in particle physics.12
Before their work, the standard model of particle physics lacked the mathematical foundation for detailed calculations. The electroweak theory, which unifies electromagnetism and the weak nuclear force, had this issue. \u2019t Hooft and Veltman developed a method of renormalization to address nonsensical infinite results in calculations. This allowed them to predict properties of particles like the W and Z bosons and the mass of the top quark, which was later discovered. Their contributions earned them the 1999 Nobel Prize in Physics.123
