Physicists Solve a Big Quantum Mystery. Now, Old Results Don’t Add Up.

The strong force, however, is not so easy to deal with. In his doctoral thesis in 2018, Keshavarzi helped hone an alternative way of understanding the strong force, called the data-driven method. In this method, physicists don’t try to predict how often muons will emit and absorb groups of quarks. Using the data-driven method, physicists set out to calculate the expected size of the muon’s magnetic wobble. Wrangling LatticesNot all physicists pursued the data-driven method to calculate the muon’s wobble.
