Modified particle lifetimes as a signature of deformed relativity
arXiv:2308.03716 · doi:10.1016/j.physletb.2023.138380
Abstract
We demonstrate a compatibility between the relativity principle and the clock postulate in deformed special relativity, by identifying the relevant deformed Lorentz transformations in position space between arbitrary frames. This result leads to a first-principles correction to the dilated lifetime of fundamental particles. It turns out that these modified time dilations offer a way to scrutinize Lorentz invariance (or deviations thereof) to high precision.
