More Muon g-2 Calculations

It is becoming ever more clear that the BMW calculation of the Standard Model expected value of muon g-2 (which is consistent with the experimental results) is correct, while the Theory Initiative calculation of the Standard Model expected value of muon g-2 (which is in strong tension with the experimental results) is flawed.

Two preprints today with lattice calculations of a clean piece of the muon g-2 HVP (2301.08274, 2301.08696). Both blind. Both in perfect agreement with BMW and previous lattice results. Both in 3-4σ tension with the dispersive approach.

This needs to be taken in the the context of experimental results such as those showing that there are no lepton universality violations, disfavoring sterile neutrinos, ending a CKM matrix element measurement anomaly, and myriad searches failing to find evidence of other hypothetical new particles. 

Take as a whole, these experimental results continue to ever more tightly close the door on a whole lot of proposed extensions or modifications of the Standard Model of Particle Physics.
