A scalar leptoquark S1 near 1 TeV can raise B to mu nu to the Belle central value, but required Yukawa couplings are large and several LHC and EDM constraints already cut into that parameter space.

Scalar leptoquark effects on $B \to \mu \bar\nu$ decay
A scalar leptoquark S1 near 1 TeV can raise B to mu nu to the Belle central value, but required Yukawa couplings are large and several LHC and EDM constraints already cut into that parameter space.
