A Lepton Flavor Universality Violation Fix?

A new paper proposed a solution to the apparent violation of lepton flavor universality violation that has been observed in semi-leptonic B meson decays, by refining the Standard Model prediction calculation with a new methodology and improving the precision of one of the physical constants that is important to the calculation, rather than resorting to beyond the Standard Model physics.

While this is a preliminary result, it is a promising suggestion that one of the most intractable apparent experimental anomalies in high energy physics may be possible to resolve.
