Correlating Tauonic B Decays to the Neutron EDM via a Scalar Leptoquark

Understand

In this article we investigate the correlations between tauonic $B$ meson decays (e.g.

• $B\to \tau\nu$, $B\to D^{(*)}\tau\nu$, $B\to \pi\tau\nu$) and electric dipole moments (EDMs), in particular the one of the neutron, in the context of the $S_1$ scalar leptoquark (LQ).
• This LQ naturally arises in the R-parity violating MSSM as the right-handed down-squark.
• We perform the matching of this model on the effective field theory taking into account the leading renormalization group effect for the relevant observables.
