8. Belle II excess in B +  ⁣ → K + ν ν ˉ and Muon g − 2 Illuminating Light Dark Sector with Higgs Portal

The Belle II collaboration recently announced that they observed the B+→K+νν¯ decay process for the first time. This dineutrino mode of B+→K+νν¯ has been theoretically identified as a very clean channel. However, their result encounters a 2.7σ deviation from the Standard Model (SM) calculation. On the other hand, last year, Fermilab released new data on muon g−2 away from the SM expectation...

Optimal kinematic observables are often defined in specific frames and then approximated at the reconstruction level. We show how multi-dimensional unfolding methods allow us to reconstruct these observables in their proper rest frame and in a probabilistically faithful way. We illustrate our approach with a measurement of a CP phase in the top Yukawa coupling.
